The valve and a water pressure system can be connected by the following ways: a, the upper part pressure-testing port of the valve is connected with the high-pressure pump through a pipe line and a joint and the lower part pressure-testing port is connected with the low-pressure pump and the energy accumulator through the pipe line and the joint; b, the lower part pressure-testing port is connected with the high-pressure pump and the upper part pressure-testing port is communicated with atmospheric air; c, the upper part pressure-testing port is connected with a volume tester and the lower part pressure-testing port is connected with the low-pressure pump and the energy accumulator. Due to the adoption of the scheme, the utility model utilizes different pipe line connecting ways and pressure-testing pressure grades and can comparably fully test the sealability of the underwell casing valve and the action accuracy of a valve plate when the liquid cylinder drives the opening cylinder to move upward and downward.
Description
Technical field
The utility model relates to the test unit of a kind of oil development with subsurface tool, particularly a kind of down-hole casing valve body test unit.
Background technology
In order to protect hydrocarbon zone better, each oily company requires that the down-hole all will keep under-balanced state, said overall process under-balance technology that Here it is in opening the whole process that oil reservoir to completion finishes.The down-hole isolation technology that adopts casing valve is to realize the simplest and the most direct, the safe technology of overall process under-balance drilling, so down hole sleeve valve begins to obtain wide popularization and application.
Down hole sleeve valve is a kind of sleeve pipe stop valve of full pit shaft, is installed on the dark sleeve pipe of the supreme km of the following hundreds of of well head, and oil gas and pressure under the valve plate closed condition can barrier wells guarantee the well head safe operation; Allow down-hole equipment to pass through in opening.But as the ingredient of protector string, the function that down hole sleeve valve also must have the packing oil-gas-water layer, reinforce oil reservoir and stabilizing borehole, therefore the basic demand for down hole sleeve valve has following several respects: 1. the intensity of valve body and high-pressure tightness are good; 2. the switch motion accuracy of valve plate is good; 3. when valve plate is closed, little by the leakage rate of sealing surface of valve plate.For guaranteeing the functional reliability of casing valve, must at first carry out strict shop experiment and check in the down-hole.
But as a kind of novel subsurface tool, at present comprehensive inadequately to the measuring means of down hole sleeve valve, there is not the rig for testing of system, even some staff also understands inadequately to the performance and the job procedure of valve, therefore press for the laboratory testing rig of a cover comparison system, can not only completely examine the performance of down hole sleeve valve, can also make the field personnel understand the job procedure and the using method of this valve intuitively.
Summary of the invention
For checking the every performance of down hole sleeve valve all sidedly, the purpose of this utility model is to provide a kind of down-hole casing valve body test unit to society.
For realizing described purpose, a kind of down-hole casing valve body test unit that the utility model proposes comprises hydraulic pump system [1], fluid cylinder [12] and valve body [8], high-pressure pump [4], low-lift pump [5], accumulator [6], open end can [9], web member [11], the cylinder body of fluid cylinder [12] and valve body [8] are tightly connected by web member [11], and the O-ring seal that the piston rod of fluid cylinder [12] passes web member [11] is connected with open end can [9]; Valve body [8] can adopt following several mode to be connected with hydraulic pressure system [13]: the top pressure testing mouth [10] of a. valve body [8] is connected with high-pressure pump [4] with joint [2] by pipeline, and bottom pressure testing mouth [7] is connected with accumulator [6] with low-lift pump [5] with joint [2] by pipeline; B. bottom pressure testing mouth [7] is connected with high-pressure pump [4], and top pressure testing mouth [10] is connected with atmosphere; C. top pressure testing mouth [10] is connected with volume tester [3], and bottom pressure testing mouth [7] is connected with accumulator [6] with low-lift pump [5].
Owing to adopt such scheme, utilize different pipeline connected modes and pressure test pressure grade, drive open end can [9] when moving up and down at fluid cylinder [12], can test the sealing of down hole sleeve valve and the action accuracy of valve plate more all sidedly.
Description of drawings
Fig. 1 is a kind of connection diagram of down-hole casing valve body test unit.
1. hydraulic pump systems, 2. joints, 3. volume testers, 4. high-pressure pumps, 5. low-lift pumps, 6. accumulators, 7. bottom pressure testing mouths, 8. valve bodies, 9. open end cans, 10. top pressure testing mouths, 11. web members, 12. fluid cylinders, 13. hydraulic pressure systems among the figure
Embodiment
Now the utility model is further described in conjunction with Figure of description.
In Fig. 1, when the top pressure testing mouth [10] of valve body [8] is connected with high-pressure pump [4] with joint [2] by pipeline, bottom pressure testing mouth [7] is by pipeline and joint [2] and low-lift pump [5] and accumulator [6] when being connected, at first close valve plate, open low-lift pump [5] and make and keep certain pressure in valve body [8] cavity of resorption, open high-pressure pump [4] then and pump into test fluid from top pressure testing mouth [10], observing high-pressure pump [4] pump pressure changes, when pump pressure when no longer average rate rises, show pressure balance on the valve plate, it is descending to use fluid cylinder [12] to drive open end can [9], opens valve plate.This test can be simulated down when getting into down hole sleeve valve top, if under the valve plate high pressure is arranged, need pump into fluid, the balance valve plate program of pressure up and down from well head.
When bottom pressure testing mouth [7] is connected with high-pressure pump [4], when stopping up top pressure testing mouth [10], can utilize the high-pressure tightness of high-pressure pump [4] test valve plate and the intensity of valve body.
When top pressure testing mouth [10] is connected with volume tester [3], bottom pressure testing mouth [7] and low-lift pump [5] and accumulator [6] can be tested the leakage rate of valve plate when each pressure rating when being connected more exactly.
