Description
Technical field
The utility model is related to a kind of production and service shaft down-hole string anchoring downhole hardware, especially a kind of well-flushing is protected
Protect the two-way automatic anchor of oil reservoir.
Background technology
In screw bolt well production process, the main reason for causing often to examine pump, when being exactly that tubing anchor is set, makes oil pipe
Bending, causes sucker rod to generate eccentric wear, leakage with oil pipe, and current capacity increases.Secondly it is exactly that sand, wax holddown or set gas greatly cannot
Discharge in time and burn pump, and with formation depletion, flushing fluid enters oil reservoir and causes oil layer pollution, increases drain time, to increase
Cost reduces working efficiency.
Invention content
The purpose of this utility model be solve above-mentioned oil pipe bend, eccentric wear, leakage, electric current between sucker rod and oil pipe
Load increases problem, and cannot be discharged in time greatly to sand, wax holddown or set gas and make solution the problems such as burning pump, and provide
A kind of well-flushing protection two-way automatic anchor of oil reservoir, can apply straight well, inclined shaft, directional well, and need not be artificial special
Operation can two-way automatic anchoring, above propose automatic deblocking, tubing string made to remain the state of naturally drooping.
A kind of well-flushing protection two-way automatic anchor of oil reservoir, including main body, housing, block teeth, unidirectional packing element, top connection, glue
Cylinder base, steel ball, lower contact, gasket and apopore, apopore is offered in main body, and top connection is mounted on the water inlet end of main body;Two
A housing is sleeved in main body, and two housings are located at apopore both sides, and the combination of housing and main body has eccentric structure, group
With being under the action of block teeth, main body is subjected to displacement with housing for cooperation, and anchor entire outer diameter is made constantly to expand, when corner reaches
At 35 ° or so, it can be anchored automatically;Block teeth are connected between two housings in main body;Apopore is located in the middle part of main body, effect
It is that flushing fluid is flowed out by apopore, the borehole wall and anchor is cleaned, avoids and cause tubing anchor not because sand setting is excessive
It can smooth unfreezing;Rubber tube seat is nested with unidirectional packing element in main body, and rubber tube seat links together unidirectional packing element with lower contact, single
Effect to packing element is liquid under the action of unidirectional packing element, and unidirectional packing element expansion sealing tubing covers annular space, and flushing fluid will not enter
Stratum;The effect of rubber tube seat is that fixed unidirectional packing element is supported not moved on main direction;In unidirectional packing element and rubber tube seat
Between be equipped with gasket, effect is will to be connected more appropriate between unidirectional packing element and rubber tube seat;Lower contact is mounted on the another of main body
End, inside added steel ball.
There is screw thread inside the top connection, when use is spun on together with screw pump lower end, and screw pump drives anchor rotation
Turn.
It is the frictional force increased between the borehole wall and anchor that the housing surrounding and block teeth surface, which has groove, effect,.
The working theory and processing of the utility model
It is latter with going into the well that anchor is connected on screw pump lower end, under on perforated interval top, under be directly seated in oil after complete tubing string
Pipe hanger generates frictional force when screw pump works normally between rotor and pump barrel, anchor body rotation is driven, in the work of block teeth
Under, main body is subjected to displacement with housing, and anchor entire outer diameter is made constantly to expand, can be automatic when corner reaches 35 ° or so
Anchoring, reversion can be also anchored, and when needing well-flushing, liquid is under the action of unidirectional packing element, unidirectional packing element expansion sealing tubing lantern ring
Sky, flushing fluid will not enter stratum, by anchor well-flushing inlet opening, are directly entered pump barrel, complete well-flushing, while to anchor
It is inside and outside that thorough cleaning has also been made, it avoids and causes tubing anchor cannot smooth unfreezing because sand setting is excessive.
The beneficial effects of the utility model:
1. need not manually do special operation can be anchored automatically, no matter straight well, inclined shaft or directional well can be anchored, anchor
Tubing string after fixed is to naturally droop, and can reduce rod tube friction, extends pump detection period.
2. the big well of pair casing gas, can be discharged by apopore, avoids and burn pump because of the big idle running of gas.
3. while flushing fluid is not into oil reservoir, tubing anchor can be cleaned thoroughly, while thorough to being had also been made inside and outside anchor
Bottom is cleaned.
