Description

A kind of Oil Well packer
Technical field
The utility model belongs to oil well sealer field, more particularly to a kind of Oil Well packer.
Background technology
Blowout preventer, is a kind of corollary equipment applied to well mouth of oil well, and its structure generally includes a vertical tube, two transverse tubes And be separately mounted to be provided with rubber seal on the core body of two leading screws and two semicirculars in two transverse tubes, core body, Core body is arranged on the end of leading screw, two core body relative engagement one annular cylindric sealing surfaces of formation, so that it will be clipped in Between sucker rod both sides sealing up and down isolation, prevent the liquid of underground from being returned out from well head.In production practices, due to using year The reason such as limit and quality, the rubber seal of blowout preventer core body thereon is easy to damage, it is necessary to which maintenance is changed often.However, In the prior art, service worker changes necessary kill-job operation during core body, could operate, and during kill-job operation, no matter using in station Hot wash pump or kill-job car can all bring larger financial burden to oil recovery unit.
Utility model content
The utility model provides a kind of Oil Well packer, to solve the problems mentioned in the above background technology.
The technical problem that the utility model is solved is realized using following technical scheme:The utility model provides a kind of oil Well blowout preventer, including a vertical tube and two transverse tubes, the upper and lower ends of vertical tube are each provided with a method for being used to be connected with well head Orchid, two transverse tubes are symmetrically connected in the both sides of vertical tube, every transverse tube be provided with a leading screw and core body, and core body is arranged on silk The end of thick stick, the both sides of described vertical tube are each provided with a threaded connection mouth, and two described transverse tubes are connected by screw thread respectively Interface is connected on vertical tube, and transverse tube is insertion sealed structure with being threadedly coupled between mouth, and the end of described transverse tube passes through spiral shell Line is connected with thread bush, and the center of thread bush is provided with screwed hole, and described leading screw is threadedly attached in screwed hole, described The side of transverse tube be provided with branch pipe, the end of branch pipe, which is provided with end socket, described transverse tube, is additionally provided with spheroid and and ball The lip ring of the sphere matching of body, the internal diameter and length of described branch pipe are all higher than the diameter of described spheroid.
Described lip ring is made up of polytetrafluoroethylene (PTFE).The side of described lip ring is provided with oblique cut Mouthful.
The beneficial effects of the utility model are:The utility model is provided with spheroid, normal work in the branch pipe on transverse tube When, spheroid is always positioned in branch pipe, now, and core body can be movable within the specific limits, to ensure that blowout preventer uses function substantially Realize, when core body is damaged, core body can be taken out from the end of transverse tube, be changed.After core body takes out, work of the spheroid in gravity Fallen naturally with lower, finally fitted with lip ring, so that the passage in transverse tube thoroughly be shut, playing prevents down-hole liquid The effect flowed out along transverse tube.Therefore, the utility model is when changing blowout preventer core body, it is to avoid Produced Liquid sprays, and not only eliminates The cost burden that kill-job operation is brought, and meet environmental requirement of the crude oil without outflow., will after the utility model comes into operation , dependence of stand outer kill-job equipment interior to station when changing blowout preventer core body is broken away from, fundamentally solves to change the problem of core body inconvenience, Save the operating cost of basic unit's oil recovery unit.
Brief description of the drawings

Fig. 2 is overall structure diagram of the present utility model;
Fig. 3 is the structural representation of lip ring.
In figure:1- leading screws, 2- thread bush, 3- transverse tubes, 4- core bodys, 5- lip rings, 6- spheroids, 7- threaded connection mouths, 8- end sockets, 9- vertical tubes, 10- branch pipes, 11- otch.
Embodiment
The utility model is described further below in conjunction with accompanying drawing:
The present embodiment includes a vertical tube 9 and two transverse tubes 3, and the upper and lower ends of vertical tube 9, which are each provided with one, to be used for and well The flange of mouth connection, two transverse tubes 3 are symmetrically connected to be provided with a leading screw 1 and core in the both sides of vertical tube 9, every transverse tube 3 Body 4, core body 4 is arranged on the end of leading screw 1.It is above common structure of the prior art, will not be repeated here.
The both sides of described vertical tube 9 are each provided with a threaded connection mouth 7, and two described transverse tubes 3 pass through screw thread respectively Connector 7 is connected on vertical tube 9, and transverse tube 3 is insertion sealed structure with being threadedly coupled between mouth 7, the end of described transverse tube 3 Thread bush 2 is connected through a screw thread, the center of thread bush 2 is provided with screwed hole, and described leading screw 1 is threadedly attached in screw thread In hole, the side of described transverse tube 3 is provided with branch pipe 10, and the end of branch pipe 10, which is provided with end socket 8, described transverse tube 3, also to be set It is equipped with spheroid 6 and the lip ring 5 matched with the sphere of spheroid 6, the internal diameter and length of described branch pipe 10 are all higher than institute The diameter for the spheroid 6 stated.
Spheroid 6 is provided with branch pipe 10 of the utility model on transverse tube 3, during normal work, spheroid 6 is always positioned at branch pipe In 10, now, core body 4 can be movable within the specific limits, to ensure that blowout preventer uses the realization of function substantially, when core body 4 is damaged When, core body 4 can be taken out from the end of transverse tube 3, be changed.After core body 4 takes out, spheroid 6 is under gravity under nature Fall, finally fitted with lip ring 5, so that the passage in transverse tube 3 thoroughly be shut, playing prevents down-hole liquid along transverse tube 3 The effect of outflow.Therefore, the utility model is when changing blowout preventer core body 4, it is to avoid Produced Liquid sprays, and not only eliminates kill-job work The cost burden that industry is brought, and meet environmental requirement of the crude oil without outflow.After the utility model comes into operation, it will break away from more , dependence of stand outer kill-job equipment interior to station when changing blowout preventer core body 4, fundamentally solves to change the problem of the inconvenience of core body 4, saves The operating cost of basic unit's oil recovery unit.
, it is necessary to which the entirety of transverse tube 3 first is rotated into 180 degree along its own axis when installing new core body 4 into transverse tube 3, make ball Body 6 is returned in branch pipe 10 under gravity, so that core body 4 passes through.Two transverse tubes 3 are connected through a screw thread mouth 7 and are connected to respectively On vertical tube 9, to ensure that the operation for rotating transverse tube 3 can be realized in structure, transverse tube 3 is with being threadedly coupled between mouth 7 using insertion Formula sealing structure (utilizes O-ring sealing), without compressing sealing using pad, it is ensured that during rotation transverse tube, sealing is not It can fail.
Described lip ring 5 is made up of polytetrafluoroethylene (PTFE), and the material has corrosion-resistant, and wear-resistant, service life is long The characteristics of, it is ensured that the reliable sealing between spheroid 6 and transverse tube 3.
The side of described lip ring 5 is provided with oblique otch 11 so that the also replaceable ring under shut-in well state Shape seal 5, solves replacing lip ring 5 and shut-in well can not while the problem of carrying out, it is to avoid well during replacing sealing ring Lower liquid overflows.
