The specific embodiment
Below in conjunction with accompanying drawing, varied angle horizontal well analogue experiment installation described in the utility model is elaborated.A kind of varied angle horizontal well analogue experiment installation, comprise dummylevel pit shaft 20, dummylevel pit shaft 20 contains a plurality of dummylevel wellbore sections 21, between two adjacent dummylevel wellbore sections 21, by connecting hose, be communicated with, dummylevel pit shaft 20 is connected with for changing the adjusting device of the angle of dummylevel wellbore section 21, as shown in Figure 1.
Dummy level pit shaft 20 contains two kinds of embodiments, the first dummy level pit shaft 20 contains two dummy level wellbore sections 21, dummy level wellbore section 21 is 7 " transparent organic glass sleeve pipes 14, as shown in the dummy level pit shaft 20 of Fig. 1 lower right side, between two transparent organic glass sleeve pipes 14, by connecting hose 13, be communicated with, in Fig. 1, the transparent plane glass bushing 14 in dummy level pit shaft 20 left sides is connected with adapter flange 4 by fixing hoop 5, and in Fig. 1, the transparent plane glass bushing 14 on dummy level pit shaft 20 right sides is also connected with adapter flange 4 by fixing hoop 5.The second dummy level pit shaft 20 also contains two dummy level wellbore sections 21, dummy level wellbore section 21 comprises 51/2 " transparent organic glass screen casing 6 and is set in 95/8 " transparent organic glass sleeve pipe 7 outside described transparent organic glass screen casing 6, as shown in the dummy level pit shaft 20 of right upper portion in Fig. 1, between two transparent organic glass screen casings 6, by connecting hose 8, be communicated with, between two transparent organic glass sleeve pipes 7, by connecting hose 9, be communicated with, in Fig. 1, the transparent plane glass bushing 7 in dummy level pit shaft 20 left sides is connected with adapter flange 4 by fixing hoop 5, in Fig. 1, the transparent organic glass sleeve pipe 7 on dummy level pit shaft 20 right sides is also connected with adapter flange 4 by fixing hoop 5.These two kinds of dummy level pit shafts 20 can be used separately, can mode as shown in Figure 1 be used in combination.
Owing to being communicated with by connecting hose between two adjacent dummylevel wellbore sections 21, so just can change the angle of dummylevel wellbore section 21 by the position of described adjusting device change dummylevel wellbore section 21 one or both ends.This varied angle horizontal well analogue experiment installation can be used for the experimental study of flow pattern fluidised form, tester response relation and screen casing leakage etc. in the pipeline under horizontal well small angle variation.Concrete, as shown in Figure 1, adjusting device is liftingsupport 11, liftingsupport 11 is connected between dummylevel wellbore section 21 and described connecting hose, by regulating thehandle 12 on liftingsupport 11, just can change the height of one end that dummylevel wellbore section 21 is connected with described connecting hose, thereby change dummylevel wellbore section 21 with respect to the angle of horizontal direction.Meanwhile, between dummylevel wellbore section 21 and adapter flange 4, be also provided with liftingsupport 11, as shown in Figure 1, the below of each dummylevel pit shaft 20 is provided with 4 lifting supports 11.In the present embodiment, only introduced the height that changes dummylevel wellbore section 21 one end, dummylevel wellbore section 21 also can change in its horizontal direction by another way as the displacement perpendicular to Fig. 1 paper direction.
The circulating system of this varied angle horizontal well analogue experiment installation for being connected by pipeloop 3, the two ends of dummylevel pit shaft 20 are respectively arranged with the adapter flange 4 for being fixedly connected with dummylevel wellbore section 21, and adapter flange 4 is also connected withliquid valve 10.
Described varied angle horizontal well analogue experiment installation is also provided with for the injection device to dummylevel pit shaft 20 filling liquids.Described injection device comprises oil tank 18 andwater pot 19, and oil tank 18 is connected with dummylevel pit shaft 20 by agitator 15 with water pot 19.Concrete, as shown in Figure 1, oil tank 18 is connected with agitator 15 by stabilizedpressure pump 17,flow meter 16 successively, simultaneously,water pot 19 is connected with agitator 15 with anotherflow meter 16 by another stabilizedpressure pump 17 successively, and agitator 15 is being connected with the adapter flange 4 of arrival end by pipeloop 3.Described varied angle horizontal well analogue experiment installation is also provided with for reclaiming the retracting device of dummylevel pit shaft 20 interior liquid, and described retracting device comprisesoil water separator 2, andoil water separator 2 is connected withwater pot 19 with oil tank 18.Concrete,oil water separator 2 is connected with the adapter flange 4 of the port of export by pipeloop 3, and the bottom ofoil water separator 2 is provided with support 1, andoil water separator 2 can utilize gravity that oil is separated with water, and separated water is delivered inwater pot 19, separated oil is delivered in oil tank 18.
The mode of occupation of this varied angle horizontal well analogue experiment installation is as follows:
In Fig. 1, oil water separator 2 is placed on support 1, the high 2m of support 1, can the water of separating and oil circulation be transported in water pot 19 and oil tank 18 by Action of Gravity Field, in the time of experiment, the oil of water pot 19 and water and oil tank 18 enters in agitator 15 by stabilized pressure pump 17 and flow meter 16 according to experiment ratio, after oil mixing with water is even, enter 3 " pipeloops 3, then enter in the visual transparent organic glass pipe 14 of 7 ", instrument can be placed on 14 li of transparent organic glass pipes and test, two section of 7 " transparent organic glass pipe is by 7 " connecting hoses 13, form a dummy level pit shaft 20, the height of controlling lifting supports 11 by handle 12 can be adjusted dummy level pit shaft and change between 0 °~± 15 ° of levels, flow pattern characteristics of fluid state and instrument response characteristic test research in the time of can completing like this different angles variation.As a same reason, fluid can carry out different angles flow pattern characteristics of fluid state and instrument response characteristic test research while changing while entering the visual transparent organic glass screen casing 6 of 51/2 ", can also carry out the research of screen casing leakage characteristics, the fluid of leakage enters in the visual transparent organic glass sleeve pipe 7 of 95/8 ", the size of wastage can be flowed in graduated cylinder and be measured by liquid valve 10, then, liquid is entering oil water separator 2 from pipeloop 3, thereby can circulate said process.
The above; be only specific embodiment of the utility model, can not limit the scope that utility model is implemented with it, so the displacement of its equivalent assemblies; or the equivalent variations of doing according to the utility model scope of patent protection and modification, all should still belong to the category that this patent is contained.
