一种柱塞气举装置采出油系统A plunger gas lift device production oil system

技术领域technical field

本发明涉及石油开采技术领域，尤其涉及一种柱塞气举装置采出油系统。The invention relates to the technical field of oil exploitation, in particular to an oil recovery system of a plunger gas lift device.

背景技术Background technique

油井自喷期间，来源于地层的压力和地层的高压气具有足够的能量可以将原油举升到地面。当油井的地层能量不足以使原油流到地面时，就需要使用气举装置来实现。柱塞气举装置作为气举装置的一种，广泛应用于采油生产中。During oil well blowout, the pressure from the formation and the high-pressure gas in the formation have enough energy to lift crude oil to the ground. When the well's formation energy is insufficient to allow crude oil to flow to the surface, a gas lift device is required to do so. As a kind of gas lift device, plunger gas lift device is widely used in oil production.

现有技术中，套管可以伸入油气井中，柱塞气举装置主要包括：气动阀、控制器以及柱塞本体；气动阀与油管连通，控制器能够控制气动阀打开或关闭。柱塞本体可以在井道内部的上下运动；具体地，当油套环空压力升高到一定值或间隔一定时间后，通过控制器开启气动阀，油管内柱塞以上的气体立刻排出，形成油套环空高压、油管低压的系统，在压差的作用下柱塞本体从油管底部向井口运动，从而将柱塞本体以上液体向上举升并通过气动阀排出；当柱塞本体到达井口后将停留在一端时间，以将井筒内的气、液充分排出；在控制器关闭气动阀后，柱塞本体可以在其重力作用下下落至油管底部，等待下一次举升。In the prior art, the casing can be extended into the oil and gas well, and the plunger gas lift device mainly includes: a pneumatic valve, a controller and a plunger body; the pneumatic valve is connected with the oil pipe, and the controller can control the opening or closing of the pneumatic valve. The plunger body can move up and down inside the well; specifically, when the annular pressure of the oil casing rises to a certain value or after a certain period of time, the pneumatic valve is opened by the controller, and the gas above the plunger in the oil pipe is immediately discharged to form oil Under the action of pressure difference, the plunger body moves from the bottom of the tubing to the wellhead, so that the liquid above the plunger body is lifted upwards and discharged through the pneumatic valve; when the plunger body reaches the wellhead, the Stay at one end for a long time to fully discharge the gas and liquid in the wellbore; after the controller closes the pneumatic valve, the plunger body can fall to the bottom of the tubing under its gravity, waiting for the next lift.

根据上述，目前现有技术中的气举装置存在一个严重缺陷，就是无法实现自身直径的调节控制，无法根据石油井道或油管内壁直径的大小进行适应性调整，因此容易在气举装置和井道之间存在缝隙，导致气液泄漏，从而影响了气举作业。故而鉴于以上缺陷，实有必要设计一种柱塞气举装置采出油系统。According to the above, there is a serious defect in the gas lift device in the prior art, which is that it cannot realize the adjustment and control of its own diameter, and cannot make adaptive adjustments according to the diameter of the inner wall of the oil well or tubing, so it is easy to install between the gas lift device and the well. There are gaps between them, resulting in gas-liquid leakage, which affects the gas lift operation. Therefore, in view of the above defects, it is really necessary to design a plunger gas lift device production oil system.
