Description
Technical field
The utility model relates to a kind of oil well workover tool, particularly the antifouling gas anchor of a kind of oil well well workover slot.
Background technology
In recent years, Exploration of Low-permeability Oil Reservoirs is developed, and proportion is larger, oil well liquid-supplying is generally poor, simultaneously along with the decline of stratum energy, degassed phenomenon is also relatively more serious, uses gas anchor to have this problem of comparatively terminating an agreement preferably, and portion gas is separated by the effect of gas anchor exactly before downhole fluid enters pump, reduce gas to the impact of pump, improve pump efficiency, gas anchor is contained in the entrance of pump, before oil enters pump, portion gas is wherein separated, reduce the tolerance entered in pump barrel.
But, along with the prolongation of recovery time, corrosion and scaling, the various booty such as oil sludge and sand causes pit shaft more and more dirtier, cause the operation success rate that once drives a well low, its main cause is: the low liquid of oil well low yield, feed flow is not enough, oil well pump is hung dark, pit shaft dirt, the situations such as dirt, easily occur after causing oil well operation because new pump pumping capacity is strong, make pit shaft foul enter pump barrel and cause two valve work abnormal, need repeatedly to rectify and improve after causing driving a well, even need to do over again ability normally, cause one-time success rate low, also be unfavorable for oil layer protection simultaneously, increase operation and account for product, manpower, the waste of material resources.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of oil well well workover slot antifouling gas anchor, stops the booty being greater than 1.5mm to enter pump barrel, reduces the booty entering pump barrel, play the effect of protection oil well pump.
Its technical scheme is: comprise lower contact, outer tube, interior pipe, top connection, recessed joint, sealing wiper block, back-up block, slot, the two ends of described outer tube connect lower contact and top connection respectively, and lower contact is provided with a circle recessed joint, connect outer tube by recessed joint, and be provided with protruding sealing wiper block outside the junction of recessed joint and outer tube; Be provided with interior pipe at the inner chamber of outer tube, one end of described interior pipe is connected with lower contact, and the other end is closed end, and is provided with back-up block in the outside of closed end, by the contact internal walls of back-up block and outer tube; Described outer tube is provided with the finedraw that multiple tracks width is less than 1.5mm, described finedraw be cut into the tangential direction of direction along outer tube outer wall.
The outer end of above-mentioned top connection is centrum shape, is connected with oil well pump by top connection.
It is centrum shape outside the internal diameter of above-mentioned lower contact.
Above-mentioned sealing wiper block is semicircular structure.
The beneficial effects of the utility model are: this finedraw be cut into the tangential direction of direction along outer wall of steel pipe, rotate into descending after making liquid enter gas anchor along steel pipe inner wall, the dirt being only less than 1.5mm just can enter annular cavity, has the function of cutting seam sieve tube interception fine particle; In addition, also there is the degassed function of common gas anchor; And there is the function that booty caught by dirt trap.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is cross-sectional view of outer tube of the present utility model;
In upper figure: lower contact 1, outer tube 2, interior pipe 3, top connection 4, recessed joint 5, sealing wiper block 6, back-up block 7, slot 8.
Detailed description of the invention
1-2 by reference to the accompanying drawings, the utility model will be further described:
The utility model comprises lower contact 1, outer tube 2, interior pipe 3, top connection 4, recessed joint 5, sealing wiper block 6, back-up block 7, slot 8, the two ends of described outer tube 2 connect lower contact 1 and top connection 4 respectively, and lower contact 1 is provided with a circle recessed joint 5, connect outer tube 2 by recessed joint 5, and be provided with protruding sealing wiper block 6 outside recessed joint 5 with the junction of outer tube 2; Be provided with interior pipe 3 at the inner chamber of outer tube 2, one end of described interior pipe 3 is connected with lower contact 1, and the other end is closed end, and is provided with back-up block 7 in the outside of closed end, by the contact internal walls of back-up block 7 with outer tube 2; Described outer tube 2 is provided with the finedraw 8 that multiple tracks width is less than 1.5mm, described finedraw 8 be cut into the tangential direction of direction along outer tube 2 outer wall.
Wherein, the outer end of top connection 4 is centrum shape, is connected with oil well pump by top connection 4; Be centrum shape outside the internal diameter of above-mentioned lower contact 1, above-mentioned sealing wiper block 6 is semicircular structure, like this, makes it both serve sealing and centralizing function in use, owing to being semicircular profile, also slow down the wearing and tearing to other pipe fittings.
The course of work of the present utility model is: rotate into descending after liquid enters gas anchor along steel pipe inner wall, and the dirt being only less than 1.5mm just can enter annular cavity, and annularly cavity outer wall is descending under the influence of centrifugal force, falls into gas anchor lower end.And liquid enters through gas anchor lower end on the joint-cutting of inner chamber steel pipe and is advanced into oil well pump, even if there is a small amount of small dirt to enter oil well pump, also can be discharged pit shaft, the normal work of oil well pump can not be affected, and most of dirt can in gas anchor annular steel pipe sand setting hole and fall into sand sediment pipe.At the upper end baffle plate in addition in slot gas anchor inner chamber steel pipe sand setting hole, prevent dirt up.
In addition, it should be noted that the utility model has three functions: one is have the degassed function of common gas anchor; Two is have the function that booty caught by dirt trap; Three is the functions with cutting seam sieve tube interception fine particle.
