背景技术Background technique
近年来随着我国经济迅猛发展，提升了对上游资源的需求，带动了地勘事业迅速发展，也促进了勘探技术的发展，由于浅部资源已面临枯竭，地质勘探逐渐的由浅部向深部延伸。In recent years, with the rapid development of my country's economy, the demand for upstream resources has increased, which has led to the rapid development of geological exploration and the development of exploration technology. Due to the depletion of shallow resources, geological exploration has gradually extended from shallow to deep .
金刚石绳索取心钻进是一种无需频繁提钻的钻进工艺，在深部的钻探工程中会拥有着更多的技术优势，在使用金刚石绳索取心钻具钻孔深度超过500米左右，投放内管时，无法准确的判断内管是否投放到位，现场完全凭借经验，为了确保内管投放到位，避免打“单管”问题的出现，往往预留了过多的等待时间，增加了钻探生产的辅助时间。Diamond wireline core drilling is a drilling process that does not require frequent drill lifting. It will have more technical advantages in deep drilling projects. When using diamond wireline core drilling tools to drill holes with a depth of more than 500 meters, put in When the inner pipe is used, it is impossible to accurately judge whether the inner pipe is put in place. The site relies entirely on experience. In order to ensure that the inner pipe is put in place and avoid the occurrence of "single pipe" problems, too much waiting time is often reserved, which increases drilling production. auxiliary time.
现有技术，S75绳索取心钻具结构上，具有到位报信的机构，由片状的阀堵以及挂簧、压簧和定位弹簧等组成，但在实际使用时，时常出现憋泵、吸附、抽吸等问题的出现，致使钻进无法正常进行；另一种用钢球和弹簧组成的一种到位报信机构，使用时能够起到位报信的作用，同时这种结构会造成一定的压力降损失。所以，在进行绳索取心金刚石钻进时，均不使用上述到位报信机构，现有的绳索取心钻具在结构上也都进行了简化，剔除了上述的到位报信机构，通常在500米以内的钻孔，一般都是通过倾听内管总成投放到位后的金属撞击声来确定是否投放到位，超过500米的钻孔是依据绳索内管总成投放的速度，来估算投放到位的时刻。In the prior art, the structure of the S75 wireline core drilling tool has an in-position reporting mechanism, which is composed of a sheet-shaped valve plug, a hanging spring, a compression spring and a positioning spring. However, in actual use, pump holding, adsorption, The emergence of problems such as suction makes the drilling unable to proceed normally; another kind of in-position signaling mechanism composed of steel balls and springs can play the role of in-position signaling when used, and this structure will cause a certain pressure drop loss . Therefore, the above-mentioned in-position reporting mechanism is not used during wireline coring diamond drilling, and the existing wireline core drilling tools are also simplified in structure, and the above-mentioned in-position reporting mechanism is eliminated, usually within 500 meters. For drilling holes, it is generally determined whether it is put in place by listening to the metal impact sound of the inner pipe assembly after it is put in place. For holes longer than 500 meters, the time of putting in place is estimated based on the speed of the rope inner pipe assembly.
专利CN86106661，绳索取芯钻具的功能机构，利用内管总成上采用的一轴套和水口的遮盖产生的压力来实现到位报信的机构，轴套和水口的遮盖量可以进行人工调节，以适应不同的流量和钻孔深度，但该功能也会产生压力降损失。Patent CN86106661, the functional mechanism of the rope core drilling tool, uses the pressure generated by the covering of a shaft sleeve and the nozzle used on the inner pipe assembly to realize the mechanism of in-position reporting, and the covering amount of the shaft sleeve and the nozzle can be manually adjusted. Accommodates different flow rates and drilling depths, but this function also produces pressure drop losses.
专利200920042400.3，一种线索取芯钻具，利用一钢球放置于冲洗液通道中，其下部安置一报信胶圈，投放到位后冲洗液驱动钢球通过胶圈至下部空间，同时产生波动压力，起到到位报信作用，内管打捞至地面后，需拧卸钻具复位钢球，操作麻烦。Patent 200920042400.3, a wire core drilling tool, uses a steel ball to be placed in the flushing fluid channel, and a signaling apron is placed at the lower part, and the flushing fluid drives the steel ball through the apron to the lower space after being placed in place, and at the same time generates fluctuating pressure. It plays the role of signaling in place. After the inner pipe is salvaged to the ground, it is necessary to unscrew the drilling tool and reset the steel ball, which is troublesome to operate.
专利201320537493.3，深孔内管到位报警绳索取芯钻具及其使用的压力检测系统中的到位报信机构，利用阀堵在内管投放到位时，冲洗液将阀堵顶开产生的压力进行报信，阀堵顶开后由曲杆定位，固定其打开的状态，从而减少压力降损失，待内管总成打捞至地面时需人工拨动曲杆复位，无自动复位功能，阀堵开启的开启度无法与冲洗液的流量自动匹配，当流量变化时，特别是流量变小时，会影响阀堵的定位，导致影响实际的工作效能，该结构的阀堵当有冲洗液驱动时，由于阀堵瞬间开启，产生的压力脉动小、时间短，需配备地面电子传感设备检测，成本较高。Patent 201320537493.3, Deep-hole inner pipe in-position alarm rope core drilling tool and the in-position reporting mechanism in the pressure detection system used, when the valve plug is put in place, the pressure generated by the flushing fluid pushing the valve plug back to report, After the valve plug is opened, it is positioned by the curved rod to fix its open state, thereby reducing the loss of pressure drop. When the inner pipe assembly is salvaged to the ground, it is necessary to manually toggle the curved rod to reset. There is no automatic reset function. The opening degree of the valve plug It cannot automatically match the flow rate of the flushing fluid. When the flow rate changes, especially when the flow rate becomes smaller, it will affect the positioning of the valve plug, which will affect the actual working efficiency. When it is turned on, the pressure pulsation generated is small and the time is short. It needs to be equipped with ground electronic sensing equipment for detection, and the cost is relatively high.
专利201410531122.3，内管到位发声报警绳索取心钻具，在内管总成上内置一声音电子报警装置，投放到位后通过一机构触发报警发出声音，报警装置发出的声音需要通过钻杆内的冲洗液介质以及地面的空气介质传递到人耳中，通常声波通过介质断面后无法继续传递，需要专门的声波识别器拾取声波，人耳无法直接获取到位信息，还需要相应的配套设备。该机构在每次投放时还要进行拧卸钻具，复位触发机构，操作不便，水下采用电子装置，结构复杂，成本高，特别是内管钻具工作环境差，水下电子报警装置需采取防水、防冲、防振等技术措施，在现有的技术条件下实施困难。Patent 201410531122.3, the rope core drilling tool with sound alarm when the inner tube is in place, a sound electronic alarm device is built in the inner tube assembly, and the alarm is triggered by a mechanism after it is put in place, and the sound from the alarm device needs to be flushed through the drill pipe The liquid medium and the air medium on the ground are transmitted to the human ear. Usually, the sound wave cannot continue to be transmitted after passing through the medium section. A special sound wave identifier is required to pick up the sound wave. The human ear cannot directly obtain the in-place information, and corresponding supporting equipment is required. This mechanism also needs to unscrew and unload the drilling tool every time it is put in, and reset the trigger mechanism, which is inconvenient to operate. The electronic device is used underwater, which has a complicated structure and high cost. It is difficult to implement technical measures such as waterproof, anti-shock, and anti-vibration under the existing technical conditions.
通常的绳索钻具内管定位是通过一机械方式由扭簧驱动一副弹卡来实现定位的，如我国地质系统的S75绳索钻具，美国NQ系列的钻具等，皆为公知的结构。由于结构的原因，通常的绳索钻具内管与外管间的定位存在2—5mm左右的间隙，造成绳索钻具内管总成在钻进中，存在着上下一定的窜动量，对采取的岩心有一定程度的扰动，特别是进行绳索冲击回转钻进时，严重的影响了冲击功的有效传递，降低冲击钻进效果。Usual wireline drilling inner pipe positioning is realized by a mechanical means driven by a torsion spring and a pair of cartridges, such as the S75 rope drilling of my country's geological system, the drilling tools of the NQ series in the United States, etc., are all known structures. Due to structural reasons, there is a gap of about 2-5mm in the positioning between the inner tube and the outer tube of the usual rope drilling tool, resulting in a certain amount of up and down movement of the inner tube assembly of the cable drilling tool during drilling. The rock core is disturbed to a certain extent, especially when performing rope impact rotary drilling, which seriously affects the effective transmission of impact energy and reduces the impact drilling effect.

本发明的工作原理和过程：Working principle and process of the present invention:
当打捞绳索钻具时，绳索打捞器拉动绳索捞矛装置，旋转拉杆、芯轴和活动阀堵在弹卡套内向上移动，打捞开始前，活动阀堵被锁紧装置锁紧在下端，内管总成处于锁死状态。当向上拉动捞矛头时，锁紧钢珠通过旋转拉杆移动，进入到芯轴的环槽部位，解除了活动阀堵的锁紧状态，并通过锁紧钢珠，与芯轴环槽处的台阶相配合连接，带动芯轴移动，继续拉动绳索捞矛装置，活动阀堵与阀堵座之间的通道打开。通过芯轴上移，半圆卡推动楔套向上移动，压缩压紧弹簧，楔套锥面与弹卡斜面脱离，继续拉动绳索捞矛装置，绳索取心钻具内管总成通过绳索打捞器向上移动，弹卡通过弹卡室斜面台阶的作用下，将弹卡推回，弹卡定位作用消失，继续提拉打捞器，可打捞出绳索取心钻具内管总成。When salvaging the wireline drilling tool, the rope fisher pulls the rope fishing spear device, and the rotating pull rod, mandrel and movable valve block move upward in the elastic clip sleeve. Before the fishing starts, the movable valve block is locked at the lower end by the locking device, The pipe assembly is locked. When the spear head is pulled upward, the locking steel ball moves through the rotating pull rod and enters the ring groove of the mandrel, releasing the locking state of the movable valve plug, and cooperates with the step at the ring groove of the mandrel through the locking steel ball Connect, drive the mandrel to move, continue to pull the rope spear fishing device, the passage between the movable valve plug and the valve plug seat is opened. When the mandrel moves up, the semicircle card pushes the wedge sleeve upwards, compresses the compression spring, the wedge sleeve cone surface is separated from the magazine slope, continues to pull the rope spear fishing device, and the inner pipe assembly of the rope core drilling tool goes upward through the rope fisher When the cartridge moves, the cartridge will be pushed back under the action of the sloped step of the cartridge chamber, and the positioning effect of the cartridge will disappear, and the overhauler will continue to be pulled, and the inner pipe assembly of the wireline core drilling tool can be salvaged.
当投放绳索钻具时，捞矛头、旋转拉杆、芯轴和活动阀堵只受弹簧力及其重力作用，悬挂弹簧处于最大伸缩量，而回位压紧弹簧处于最大压缩量，悬挂弹簧弹簧力F1小于压紧弹簧弹簧力F2与相关零件的重力之和F3，当在F2与F3作用下，F1＝F2+F3时，活动阀堵将冲洗液通道关闭。When putting in the wireline drilling tool, the spear head, rotating pull rod, mandrel and movable valve plug are only affected by the spring force and its gravity. The suspension spring is at the maximum expansion and contraction, while the return compression spring is at the maximum compression. F1 is less than the sum F3 of the gravity sum F2 of compressing spring spring force and relevant parts, when under the action of F2 and F3, when F1=F2+F3, movable valve plug closes flushing liquid channel.
当投放绳索钻具到位时，绳索定位悬挂机构钻具上的扶正悬挂环嵌套在钻具外管的座环内，用于悬挂和密封钻具，将绳索钻具的内管总成与外管钻具间的环状冲洗液通道关闭，这时被封闭的冲洗液压力增加，产生水击力作用在活动阀堵上，压缩悬挂弹簧驱动活动阀堵、芯轴、旋转拉杆、捞矛头等相关零件向下移动，当阀堵片越过阀堵座的配合表面时，水击力开始作用在补偿套的上端面，活动阀堵和补偿套向下移动，直至活动阀堵的阀堵座打开与补偿套之间的通道，此时由于作用在补偿套上端的压力降低，补偿套在补偿弹簧弹簧力的作用下回到初始位置，活动阀堵被锁紧装置锁死，致使产生的压力损失小，同时在活动阀堵的驱动过程中，产生的压力对地面到位报信，芯轴推动楔套的斜面将弹卡推出，并进入绳索钻具外管部分的弹卡室，完成定位作用。When the rope drilling tool is put in place, the righting suspension ring on the drilling tool of the rope positioning suspension mechanism is nested in the seat ring of the outer tube of the drilling tool to suspend and seal the drilling tool, and connect the inner tube assembly of the cable drilling tool with the outer tube The annular flushing fluid channel between the pipe drilling tools is closed. At this time, the pressure of the closed flushing fluid increases, and the water hammer force is generated to act on the movable valve plug. The compressed suspension spring drives the movable valve plug, mandrel, rotating pull rod, spearhead, etc. The relevant parts move downward, when the valve plug crosses the matching surface of the valve plug seat, the water hammer force begins to act on the upper end surface of the compensation sleeve, and the movable valve plug and compensation sleeve move downward until the valve plug seat of the movable valve plug is opened At this time, due to the decrease of the pressure acting on the upper end of the compensation sleeve, the compensation sleeve returns to the initial position under the spring force of the compensation spring, and the movable valve plug is locked by the locking device, resulting in pressure loss At the same time, during the driving process of the movable valve plug, the pressure generated will signal to the ground that the position is in place. The mandrel pushes the inclined surface of the wedge sleeve to push the cartridge out, and enters the cartridge chamber of the outer tube of the wireline drilling tool to complete the positioning function.

本发明的工作原理和过程：Working principle and process of the present invention:
参阅图1、图2、图3和图4所示，当打捞绳索钻具时，绳索打捞器拉动绳索捞矛装置11，旋转拉杆121、芯轴124和活动阀堵142在弹卡套135内向上移动，打捞开始前，活动阀堵142被锁紧装置12锁紧在下端，内管总成1处于锁死状态。当向上拉动捞矛头111时，锁紧钢珠123通过旋转拉杆移动，进入到芯轴124的环槽部位，解除了活动阀堵142的锁紧状态，并通过锁紧钢珠123，与芯轴124环槽处的台阶相配合连接，带动芯轴124移动，继续拉动绳索捞矛装置11，活动阀堵142与阀堵座146之间的通道打开。通过芯轴124上移，半圆卡134推动楔套132向上移动，压缩压紧弹簧122，楔套132锥面与弹卡133斜面脱离，继续拉动绳索捞矛装置11，绳索取心钻具内管总成1通过绳索打捞器向上移动，弹卡133通过弹卡室1331斜面台阶的作用下，将弹卡133推回，弹卡133定位作用消失，继续提拉打捞器，可打捞出绳索取心钻具内管总成1。Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, when the rope drilling tool is salvaged, the rope fishing device pulls the rope spear fishing device 11, and the rotating pull rod 121, the mandrel 124 and the movable valve plug 142 are in the elastic ferrule 135 Moving upwards, before the salvage starts, the movable valve plug 142 is locked at the lower end by the locking device 12, and the inner pipe assembly 1 is in a locked state. When pulling the spear head 111 upwards, the locking steel ball 123 moves through the rotating pull rod and enters the ring groove of the mandrel 124 to release the locking state of the movable valve plug 142, and through the locking steel ball 123, it is ringed with the mandrel 124. The steps at the groove are matched and connected to drive the mandrel 124 to move, and the rope fishing spear device 11 is continued to be pulled, and the passage between the movable valve plug 142 and the valve plug seat 146 is opened. As the mandrel 124 moves up, the semicircle clip 134 pushes the wedge sleeve 132 to move upward, compresses the compression spring 122, the tapered surface of the wedge sleeve 132 is separated from the inclined surface of the bullet clip 133, and continues to pull the rope spear fishing device 11, and the inner tube of the rope core drilling tool The assembly 1 moves upwards through the rope fisher, and the bullet card 133 is pushed back by the action of the sloped step of the card chamber 1331, and the positioning function of the bullet card 133 disappears. Continue to pull the fisherman, and the rope core can be fished out Drilling tool inner tube assembly 1.
当投放绳索钻具时，捞矛头111、旋转拉杆121、芯轴124和活动阀堵142只受弹簧力及其重力作用，悬挂弹簧143处于最大伸缩量，而回位压紧弹簧122处于最大压缩量，悬挂弹簧143弹簧力F1小于压紧弹簧122弹簧力F2与相关零件的重力之和F3，当在F2与F3作用下，F1＝F2+F3时，活动阀堵142将冲洗液通道关闭。When putting in the wireline drilling tool, the spear head 111, the rotating pull rod 121, the mandrel 124 and the movable valve plug 142 are only affected by the spring force and its gravity, the suspension spring 143 is at the maximum expansion and contraction, and the return compression spring 122 is at the maximum compression Amount, suspension spring 143 spring force F1 is less than compression spring 122 spring force F2 and the gravity sum F3 of relevant parts, when under F2 and F3 effect, when F1=F2+F3, movable valve plug 142 closes flushing liquid channel.
当投放绳索钻具到位时，绳索定位悬挂机构钻具上的扶正悬挂环151嵌套在钻具外管的座环152内，用于悬挂和密封钻具，将绳索钻具的内管总成1与外管钻具2间的环状冲洗液通道关闭，这时被封闭的冲洗液压力增加，产生水击力作用在活动阀堵142上，压缩悬挂弹簧143驱动活动阀堵142、芯轴124、旋转拉杆121、捞矛头111等相关零件向下移动，当阀堵片1422越过阀堵座146的配合表面时，水击力开始作用在补偿套144的上端面，活动阀堵142和补偿套144向下移动，直至活动阀堵142的阀堵座146打开与补偿套144之间的通道，此时由于作用在补偿套144上端的压力降低，补偿套144在补偿弹簧145弹簧力的作用下回到初始位置，活动阀堵142被锁紧装置12锁死，致使产生的压力损失小，同时在活动阀堵142的驱动过程中，产生的压力对地面到位报信，芯轴124推动楔套132的斜面将弹卡133推出，并进入绳索钻具外管部分的弹卡室1331，完成定位作用。When the rope drilling tool is put in place, the righting suspension ring 151 on the drilling tool of the rope positioning suspension mechanism is nested in the seat ring 152 of the outer tube of the drilling tool to suspend and seal the drilling tool, and the inner tube assembly of the cable drilling tool The annular flushing fluid channel between 1 and the outer pipe drilling tool 2 is closed, and the pressure of the closed flushing fluid increases at this time, generating water hammer force to act on the movable valve plug 142, and the compressed suspension spring 143 drives the movable valve plug 142, the mandrel 124. Rotating pull rod 121, spear head 111 and other related parts move downward. When the valve block 1422 passes over the mating surface of the valve seat 146, the water hammer force begins to act on the upper end surface of the compensation sleeve 144. The movable valve block 142 and the compensation The sleeve 144 moves downward until the valve plug seat 146 of the movable valve plug 142 opens the channel between the compensation sleeve 144. At this time, due to the pressure reduction acting on the upper end of the compensation sleeve 144, the compensation sleeve 144 under the action of the spring force of the compensation spring 145 Back to the initial position, the movable valve plug 142 is locked by the locking device 12, so that the pressure loss generated is small. The inclined plane of 132 pushes out the cartridge 133, and enters the cartridge chamber 1331 of the outer tube part of the wireline drilling tool to complete the positioning function.
