Abstract
An underground hydraulic multi-stage tester, which comprises a valve body 1, an uniflow valve 2, an oil inlet 3, an adjusting ring 4, a constant pressure spring 5, a controlling loop 6, a controlling ball 7, a center tube 8, a track sliding sleeve 9, a transposition pin 10, a shell 11 and a back-moving spring 12. The utility model adopts the structure that the oil inlet is provided on the upper portion of the valve body, inside of which the uniflow valve is provided, the adjusting ring, the constant pressure spring and the controlling loop are provided consecutively on the valve body via sleeves, the center tube is arranged in the valve body via sleeves, the controlling ball is provided between the controlling ring and the center tube, the track sliding sleeve and the back-moving spring are consecutively arranged at the lower portion of the center tube via sleeves, and the transposition pin on the shell is arranged in the track sliding sleeve. When a series of this devices and a series of filters are utilized in couples, the utility model is capable of realizing 'open-close' movement as given regulations via the hydraulic drive driving the track tube and the valve body, which is capable of open and close each oil layer respectively, thereby testing each oil layer group. The utility model has a reasonable design and a simple structure, which is quite applicable to promotion and application in construction site.
Description
Technical field:
The utility model relates to the downhole measurement tools of using on a kind of oilfield, particularly a kind of hydraulically-controlled type down-hole multilevel tester.
Background technology:
In the oilfield process, test also is confined to geophysical log, the formation testing technology behind the completion perforating and the methods such as rod-pumped well annular space logging in the manufacturing process in the oilwell drilling process to oil well delamination at present.And in process of production, need the motionless flow string of a kind of application machine mode respectively each oil reservoir group to be tested especially, try to achieve the production capacity and the content of each layer oil, gas, water.For reducing cost, reduce consumption, the prediction oil well output provides foundation.
Technical scheme
The utility model purpose is to provide a kind of hydraulically-controlled type down-hole multilevel tester, and motionless flow string is tested each oil reservoir group respectively in the oil well production process, tries to achieve the production capacity and the content of each layer oil, gas, water; Close unwanted producing zone position according to the motionless flow string of test result; Testing time is unrestricted, can realize the conversion of open and close under same force value.For reducing cost, reduce consumption, the prediction oil well output provides foundation.
The utility model purpose is to realize like this; it is by valve body (1); single current valve (2); fuel feed hole (3); adjustable ring (4); level pressure spring (5); gate ring (6); control steel ball (7); central tube (8); track sliding sleeve (9); transposition pin (10); housing (11); back-moving spring (12) is formed; valve body (1) is connected with housing (11); on valve body (1) top fuel feed hole (3) is arranged; there is single current valve (2) inside; be with adjustable ring (4) on the valve body (1) successively; level pressure spring (5); gate ring (6); inside is with central tube (8); between gate ring (6) and central tube (8), control steel ball (7) is arranged; be with track sliding sleeve (9) successively in central tube (8) bottom; back-moving spring (12), the transposition pin (10) on the housing (11) drops in the track sliding sleeve (9).
Its conversion of " opening-close " different conditions drives by hydraulic pressure and spring force, after one group of rule execution, gets back to original state again, can carry out reciprocation cycle; Operating pressure is adjustable, and same device is determined to move behind the pressure, and the operating pressure during each state conversion is identical; The design of this device has the ball-and-seat structure, the conversion of the master cock action that guarantees still can to build the pressure internally under open mode.This device be connected with tubing string go into the well before, determine earlier its required on off state and regulate its action controlled pressure, go into behind the well as need test each oil-water-layer respectively or close unwanted oil reservoir with tubing string, can motionless flow string suppress and can change it and open-off status.
The utility model has fuel feed hole owing to having adopted on valve body top; there is the single current valve inside; be with adjustable ring, level pressure spring, gate ring on the valve body successively; inside is with central tube; the control steel ball is arranged between gate ring and central tube; be with track sliding sleeve, back-moving spring successively in the central tube bottom, the transposition pin on the housing drops in the track sliding sleeve.With a series of these devices and the supporting use of a series of packer, drive track pipe and valve body by hydraulic-driven and can make this device realize that according to given rule " open---close " move.And this device can also be realized the reciprocation cycle action by " open---the close " rule that designs.Can open and close each oil reservoir respectively.Each oil reservoir group is tested the purpose of trying to achieve the production capacity of each layer oil, gas, water and content and closing unwanted producing zone position according to test result thereby reach.It is reasonable in design, and is simple in structure, is well suited for field popularization application.
Description of drawings
Accompanying drawing 1 is a schematic diagram of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment
As shown in the figure; the utility model is by valve body 1; single current valve 2; fuel feed hole 3; adjustable ring 4; level pressure spring 5; gate ring 6; control steel ball 7; central tube 8; track sliding sleeve 9; transposition pin 10; housing 11; back-moving spring 12 is formed; valve body 1 is connected with housing 11; on valve body 1 top fuel feed hole 3 is arranged; there is single current valve 2 inside; be with adjustable ring 4 on the valve body 1 successively; level pressure spring 5; gate ring 6; inside is with central tube 8; at gate ring 6 and 8 of central tubes control steel ball 7 is arranged; be with track sliding sleeve 9 successively in central tube 8 bottoms; back-moving spring 12, the transposition pin 10 on the housing 11 drops in the track sliding sleeve 9.
This utility model can be in the oil well production process condition of production of each oil reservoir of dynamic test, for manager's decision-making provides foundation, enhance productivity and the oil field development effect; According to test result, can under the situation of motionless flow string, close unwanted oil reservoir with this device, save management cost, increase economic efficiency.
