Abstract
The utility model discloses a rod-type rotary oil pipe blanking plug, which solves the problem that high-pressure liquid in an oil well can be sprayed out from the oil pipe when the oil well is operated under pressure; the hydraulic oil pipe plug specifically comprises a main body, a rotary bearing, an upper cone, a sealing rubber cylinder, a rubber cylinder seat, a plurality of fixed slips, a lower cone, a centralizing body, a friction block, a compression spring and a lower joint, wherein the upper cone downwards extrudes and expands the sealing rubber cylinder to seal an oil pipe, and the fixed slips downwards anchor on the inner wall of the oil pipe along the lower cone, so that a rod-type rotary oil pipe plug is fixedly sealed in the oil pipe, the aim of preventing high-pressure liquid in a well from being sprayed out of the oil pipe is fulfilled, and guarantee is provided for implementation of operation under pressure of the oil well.
Description
Technical field
The utility model relates to and on oil field, under Operating Pressure condition, prevents the device of well inner high voltage liquid from spraying in oil pipe.
Background technology
At present, oil reservoir and ground pollution, in order to keep stratum energy, are reduced in oil field, reduce operating cost, start gradually to carry out Operating Pressure construction on rod-pumped well.And oil well is dismantled production tree under Operating Pressure condition and install in the operating process such as sucker rod, control well inner high voltage liquid is prerequisite and the key technology of implementing rod-pumped well Operating Pressure from ejection in oil pipe, and prior art can not address the above problem.
Summary of the invention
The purpose of this utility model is to provide a kind of rod-type rotation pipeline blanking plug, and this rod-type rotation pipeline blanking plug can accomplish to prevent under the prerequisite of oil well with pressure that well inner high voltage liquid from spraying in oil pipe.
For achieving the above object, the technical solution adopted in the utility model is: a kind of rod-type rotation pipeline blanking plug, comprise main body, swivel bearing, upper cone, cartridge, glue tube base, some stationary slips, lower cone, centralizer body, brake pad, Compress Spring and lower contact, in described main body, be set with successively swivel bearing, upper cone, cartridge and glue tube base, lower cone and the screwed connection of main body lower end, and fixed by safetied pin; The upper port of above-mentioned cartridge is interior cone mouth, and the tapering of this interior cone mouth and upper cone adapts, and the lower end of upper cone is inserted in the interior cone mouth of cartridge; Described stationary slip has an inner conical surface, and some stationary slips are fixed on glue tube base and circumferentially uniform along glue tube base, and above-mentioned stationary slip is fixedly connected with cone mouth in rear formation stationary slip, and the upper port of lower cone is inserted in stationary slip in cone mouth; Lower cone and centralizer body screwed connection, brake pad, Compress Spring are arranged on centralizer body, and spacing fixing by fixing pin, centralizer body and lower contact screwed connection.
The beneficial effects of the utility model: this rod-type rotation pipeline blanking plug, under the brake pad and the fricative frictional force effect of tube inner wall of centralizer body, by rotating main body, promoting stationary slip is stuck on tubing wall along the descending final seat of lower cone, and then promotion upper cone squeezes swollen cartridge sealing oil pipe, now this rod-type rotation pipeline blanking plug plays the effect of grappling and sealing oil pipe, effectively prevent that well inner high voltage liquid from spraying in oil pipe, guarantee that oil well dismantles production tree and the enforcement of the operations such as sucker rod is installed under condition with pressure.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model rod-type rotation pipeline blanking plug.
Fig. 2 is the longitudinal sectional view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
By Fig. 1 in conjunction with shown in Fig. 2: a kind of rod-type rotation pipeline blanking plug, comprise main body 1, swivel bearing 2, upper cone 3, cartridge 4, glue tube base 5, some stationary slips 6, lower cone 8, centralizer body 9, brake pad 10, Compress Spring 11 and lower contact 13, in described main body 1, be set with successively swivel bearing 2, upper cone 3, cartridge 4 and glue tube base 5, lower cone 8 and main body 1 lower end screwed connection, and fixed by safetied pin 7; The upper port of above-mentioned cartridge 4 is interior cone mouth, and the tapering of this interior cone mouth and upper cone 3 adapts, and the lower end of upper cone 3 is inserted in the interior cone mouth of cartridge 4, and upper cone 3 is descending can be applied and squeeze swollen active force cartridge 4; Described stationary slip 6 has an inner conical surface, some stationary slips 6 are fixed on glue tube base 5 and circumferentially uniform along glue tube base 5, above-mentioned stationary slip 6 is fixedly connected with interior cone mouth of rear formation, the upper port of lower cone 8 is inserted in the interior cone mouth that above-mentioned stationary slip 6 is fixedly connected with rear formation, and stationary slip 6 can be descending along the conical surface of lower cone 8; Lower cone 8 and centralizer body 9 are by screwed connection; Brake pad 10, Compress Spring 11 are arranged on centralizer body 9, and spacing fixing by fixing pin 12; Centralizer body 9 and lower contact 13 screwed connections.
Before the construction of rod-pumped well Operating Pressure, by carrying on polished rod to paraffin valve top, close complete paraffin valve, then dismantle blowout prevention box and polished rod, rod-type rotation pipeline blanking plug is connected between polished rod and rod string, between paraffin valve and blowout prevention box, installing additional after oil pipe short circuit, by rod string G.I.H again, dextrorotation polished rod driven rod formula rotation pipeline blanking plug main body 1 now, under the effect of the frictional force that the brake pad 10 on centralizer body 9 and tube inner wall produce, it is descending along the conical surface of lower cone 8 that main body 1 rotation promotes stationary slip 6, when stationary slip 6 comes downwards to its seat and is stuck on tube inner wall, upper cone 3 continues descending squeeze swollen cartridge 4 and tube inner wall sealing, when the sealing force producing between the seat card power producing between stationary slip 6 and tube inner wall and cartridge 4 and tube inner wall acquires a certain degree, continuing rotation polished rod cuts off pin, make rod-type rotation pipeline blanking plug fixing seal in oil pipe, and throw off with polished rod, now, well inner high voltage liquid is sealed in oil pipe and can spray, next just can dismantle the enforcement of the operations such as production tree and installation sucker rod.
