Abstract
The present invention relates to technical field of oil production engineering, belong to a kind of anti-sticking oil rig of Ternary composite drive well scale removal.The present invention solves the problems, such as Ternary composite drive well because of fouling holddown.It is made of upper delivery connection (1), upper scraper (2), centralizer body (3), soft seal set (4), oil-release valve cover (5), valve ball (6), valve seat (7), lower scraper (8)；It is wherein cased with soft seal set (4) outside centralizer body (3), centralizer body (3) lower end is connect with the threaded upper ends of oil-release valve cover (5), and valve ball (6) and valve seat (7) are housed inside oil-release valve cover (5).The advantages of present invention has the dirt that can wipe inside surface of subsurface pump barrel off, prevents oil well pump holddown guarantees that oil well pump works normally.
Description
Technical field
The present invention relates to technical field of oil production engineering, belong to a kind of anti-sticking oil rig of Ternary composite drive well scale removal.
Background technique
After Ternary composite drive well is imitated, it may appear that the problem of pit gear serious scale, down-hole oil tube, sucker rod and
The surface scale of oil well pump, as sucker rod pumps in pit shaft, down-hole oil tube, sucker rod and pump barrel surface
Dirty sector-meeting largely falls off.The upper end outer surface of common oil well pump is chamfering, is will form between wedge shape between upper end and pump barrel
Gap, dirty piece are easy to be deposited in the upper end of plunger；In addition, since the plunger and pump barrel of common oil well pump are steel body, plunger and pump barrel
Between gap fix, once there is dirty piece to enter the gap between plunger and pump barrel, dirty piece be easy to be stuck in plunger and pump barrel it
Between, cause plunger that cannot move up and down, oil well pump cisco unity malfunction, oil well stops production.
Plunger is stuck in inside pump barrel because of dirty piece in order to prevent, is guaranteed that plunger can normally move up and down inside pump barrel, is sent out
A kind of anti-sticking oil rig of Ternary composite drive well scale removal is illustrated, substitutes the plunger of conventional oil well pump, cooperates conventional oil well pump
Pump barrel realizes the needs of antiscale card oil pumping lifting.
Summary of the invention
The purpose of the present invention is studying that the dirt on oil pump sleeve surface can be struck off, prevent dirty piece be stuck in plunger and pump barrel it
Between, the holddown probability of oil well pump is reduced, a kind of Ternary composite drive well scale removal for extending the Ternary composite drive well cycle of operation is anti-
Card oil rig.
The present invention is achieved by the following technical solutions: it is by upper delivery connection, upper scraper, soft seal set, righting
Body, oil-release valve cover, valve ball, valve seat, lower scraper composition；Wherein the lower end of upper delivery connection and the threaded upper ends of upper scraper connect
Connect, the threaded upper ends of the lower end of upper scraper and centralizer body connect, be cased with soft seal set outside centralizer body, centralizer body lower end with go out
The threaded upper ends of oil valve cover connect, and valve ball and valve seat are housed inside oil-release valve cover, and valve ball is sitting on valve seat, the upper end of lower scraper
It is connect with the lower thread of oil-release valve cover.
Soft seal set uses ultra-high molecular weight polyethylene, and the inner surface of upper scraper is the conical surface.The outer surface of lower scraper
There are 3~6 spiral through slots.
Compared with the prior art the present invention has the advantage that
1) when pumping unit up-down stroke moves reciprocatingly, the present invention can strike off the dirt of pump barrel inner surface, prevent pump barrel fouling；Together
When upper scraper inner surface of the invention be the conical surface, the dirty piece that pit shaft is fallen can be collected, prevent dirty piece from entering plunger and pump barrel
Between.
2) present invention is equipped with soft seal set, and soft seal set uses ultra-high molecular weight polyethylene, and dirty piece can pass through soft seal
The gap of set and pump barrel will not be stuck between the present invention and the pump barrel of oil well pump, prevent holddown, guarantee Ternary composite drive well just
Often operating.
Detailed description of the invention: Fig. 1 is structure diagram of the invention；Fig. 2 is the structure diagram of upper scraper 2；Fig. 3 is lower scraper
8 main view；Fig. 4 is the A direction view of lower scraper 8.
Specific embodiment: below in conjunction with attached drawing, the invention will be further described, the present invention by upper delivery connection 1, on
Scraper 2, centralizer body 3, soft seal set 4, oil-release valve cover 5, valve ball 6, valve seat 7, lower scraper 8 form；Wherein upper delivery connection 1
Lower end connect with the threaded upper ends of upper scraper 2, the lower end of upper scraper 2 is connect with the threaded upper ends of centralizer body 3, centralizer body
3 outsides are cased with soft seal set 4, and 3 lower end of centralizer body is connect with the threaded upper ends of oil-release valve cover 5, and valve ball is housed inside oil-release valve cover 5
6 and valve seat 7, valve ball 6 be sitting on valve seat 7, the upper end of lower scraper 8 is connect with the lower thread of oil-release valve cover 5.
Soft seal set 4 uses ultra-high molecular weight polyethylene, and the inner surface of upper scraper 2 is the conical surface.The appearance of lower scraper 8
There are 3~6 spiral through slots in face.
When field operation lower tubular column, connection type of the invention is identical with common oil well pump.By it is of the invention it is upper go out
Oily connector 1 is connect with the lower thread of sucker rod, and the present invention is lowered into the pump barrel of oil well pump by rod string.Pumping unit
After well starting, the present invention is identical with the working principle of common oil pump plunger piston, realizes the crude oil in lifting oil well.Work as rod-pumped well
When upstroke, the present invention is moved upwards, and upper scraper 2 wipes the dirt of pump barrel inner surface off；When rod-pumped well down stroke, the present invention
It moves downward, lower scraper 8 wipes the dirt of pump barrel inner surface off；Soft seal set 4 of the invention has certain elasticity, when dirty piece into
Enter soft seal set 4 in the gap of pump barrel, dirty piece can cover the gap of 4 with pump barrel by soft seal, will not be stuck in the present invention with
Between the pump barrel of oil well pump, oil well pump holddown is prevented, guarantees that Ternary composite drive well runs well.
