Technical field
The utility model relates to insert pump tubing string pressure testing device, relates in particular to a kind of draining type insert pump tubing string pressure testing device.
Background technology
The tubing pump that oil field sucker rod pump oil well is used, after under pumping pipe string, finishing, must carry out the pumping pipe string pressure testing, whether miss with the check pumping pipe string, in recent years, along with the oil field is taken out increasing of well and low cost strategy deeply, the application quantity of insert pump increases year by year, but because of insert pump be under the rod string lower going-into-well, the pumping pipe string that before has been lowered to can not carry out the tubing string pressure testing, can't judge whether pumping pipe string misses, often, play lower tubular column repeatedly because of the tubing string leakage causes operation to do over again, cause underground and the dual pollution in ground, influence the oil well effective production time, increase operating cost, limited the use of insert pump.Yan Jiu insert pump tubing string pressure testing device had played insert pump tubing string pressure testing effect in the past, if insert pump tubing string pressure testing device has oil draining function, made it when needs trip out the insert pump tubing string, can release the crude oil in the tubing string, just can avoid ground pollution.
Summary of the invention
The purpose of this utility model is to provide a kind of draining type insert pump tubing string pressure testing device, overcomes the defective that the insert pump tubing string of prior art is taken crude oil pollution ground out of.
The utility model embodiment provides a kind of draining type insert pump tubing string pressure testing device, and this draining type insert pump tubing string pressure testing device comprises: top connection, main body and lower contact, wherein, described top connection and the top screwed connection of described main body; Described lower contact and described lower body part screwed connection; Described body interior is provided with spring base, spring, valve body, valve seat in proper order, and spring base screw thread wherein is screwed into main body, and an end of fixing described spring is connected with valve body at the other end of spring; Described valve seat is pressed abd fixed on valve body next door in the main body by described lower contact; This draining type insert pump tubing string pressure testing device also comprises: hollow pin, this hollow pin run through by the pressure cap ecto-entad and are arranged on described top connection sidewall.
Described hollow pin is for can sever formula hollow metal pin.
Under the effect of spring, described valve body and described valve seat are in normally open.
Be provided with metal gasket between described hollow pin and the described top connection sidewall.
Described metal gasket is the red copper pad.
The utlity model has following beneficial effect:
A kind of draining type insert pump tubing string pressure testing device that the utility model provides, be mainly used in the insert pump producing well and carry out the pumping pipe string pressure testing, solve the difficult problem that insert pump lifting tubing string can not pressure testing, realized after the tubing string pressure testing pump down, effectively prevented to do over again operation, enlarged the range of application of insert pump, reduce cost for oil production, most importantly, when needs trip out the insert pump tubing string, can release the liquid in the tubing string, avoid ground pollution.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, does not constitute qualification of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of draining type insert pump tubing string pressure testing device of the present utility model.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with embodiment and accompanying drawing, embodiment is described in further details to the utility model.At this, illustrative examples of the present utility model and explanation thereof are used to explain the utility model, but not as to qualification of the present utility model.
Embodiment one
The utility model embodiment provides a kind of draining type insert pump tubing string pressure testing device, and as shown in Figure 1, Fig. 1 is the structural representation of the utility model insert pump tubing string pressure testing device.
Please participate in Fig. 1, draining type insert pump tubing string pressure testing device of the present utility model comprises: top connection 1, main body 5 and lower contact 10, top connection 1, main body 5, lower contact 10 order screwed connections, described main body 5 inner orders are provided with spring base 6, spring 7, valve body 8, valve seat 9, wherein, spring base 6 usefulness screw threads are screwed into main body 5,6 times companies of spring base spring 7, one end of fixing spring 7, the other end at spring 7 connects valve body 8, after main body 5 and lower contact 10 screwed connections valve seat 9 is compressed, be arranged on the next door of valve body 8.Under the oil pumping state, valve body 8 is in normally open with valve seat 9 under the effect of spring force, to reduce the oil-feed resistance.
Draining type insert pump tubing string pressure testing device of the present utility model also comprises: hollow pin 3, this hollow pin 3 run through by pressure cap 2 ecto-entads and are arranged on described top connection 1 sidewall.Described hollow pin 3 can fracture under the bump of metal bar, like this, is just to have to release in the hole that hollow pin 3 forms, and realizes the purpose of draining.
In a preferred embodiment, be provided with metal gasket 4 between described hollow pin 3 and described top connection 1 sidewall.
In another preferred embodiment, described metal gasket 4 is the red copper pad.
Draining type insert pump tubing string pressure testing device of the present utility model, in work is that this draining type insert pump tubing string pressure testing device is connected on the pumping pipe string lower end, when pumping pipe string has descended the back pressure testing, pressure testing liquid flows downward with valve seat 9 via the valve body of often opening 8 fast, under liquid at high speed is impacted, make valve body 8 overcome spring force and be displaced downwardly to valve seat 9 and close sealing with it, realize the pressure testing of tubing string system.After the tubing string pressure testing was qualified, following pump rises to be taken out, and at this moment, returned to normally open at the Operating valve body 8 of spring force.Need when producing, when the insert pump tubing string is tripped out, then in down-hole string, drop into steel bump rod at well head earlier, under action of gravity, steel bump rod is to sever hollow metal pin 3 at a high speed, liquid in the tubing string is let out the oil jacket annular space from hollow metal pin 3 endoporus, reaches to get rid of in the tubing string residual crude oil and avoid polluting the purpose on ground.
