Abstract
The utility model relates to a control device for the overflowing of oil tubes, in particular to a draggable controller for the overflowing of oil tubes, wherein a core is arranged inside a housing and the top of the core is equipped with an end cap. A centralizing body passes through the end cap and is fixed to the core by a suspension body. The controller of the utility model is simple in structure and reliable and convenient in operation. The fishing head of the controller matches with conventional measurement and fishing tools in oilfields, so that additional equipments are not needed.
Description
Technical field:
The utility model relates to a kind of oil pipe excess flow control, relates in particular to a kind of salvagable oil pipe overflow controller.
Background technology:
Take out the down-hole and bore in the operation in not kill-job, overflow well, blowing commentaries on classics, need to adopt overflow controller.
Because the tube inner wall dirt is more, clogging is often arranged, and current oil pipe overflow controller diameter is bigger, need to adopt cable, rope mode of movement, throw overflow controller down shortcoming not in place, that repeatedly stop up exist to take place to be hampered midway, to stop up, and it is big and need cable, the cooperation of rope vehicle to throw overflow controller work operations amount down.
Summary of the invention:
The utility model proposes a kind of new technical scheme at the problems referred to above.The utility model is simple in structure, and is easy to use, can match with oil field test commonly used fishing tool, equipment, stops up effective.
The technical scheme that the utility model provides is:
The salvagable oil pipe overflow controller is provided with fuse in the housing, the fuse top is provided with end cap, and centralizer body passes end cap and is fixed together by suspension body and fuse.
Concrete, have groove on the inwall of housing, have through hole with the corresponding position of groove on the sidewall of fuse, suspension body passes through hole and is positioned at groove.
The centralizer body top is provided with the fishing head of umbrella.Be provided with sealing ring between housing and the fuse.
Suspension body one end is processed into sphere, and the middle part is and the cylinder of ball with diameter that the other end is the cylinder bigger than middle part cylinder diameter.
The diameter of centralizer body lower end is greater than the diameter of circular hole on the end cap.
The utility model is simple in structure, reliable, easy to operate, and fishing head matches with oil field test commonly used fishing tool, equipment, need not other procuring equipment, has saved cost.
The suspension body spherical part is embedded in the groove on the inner walls, and intermediate cylindrical partly is embedded in the fuse through hole.The centralizer body constraint suspension body other end inwardly moves, and realizes hanging, stopping up.Propose the constraint of having removed suspension body on the centralizer body.In addition, the diameter of centralizer body lower end is greater than the diameter of circular hole on the end cap, and centralizer body can upwards spur end cap and fuse, fuse pulling suspension body, the groove on the housing produces radial component to the spherical part of suspension body, forces suspension body inwardly to move, remove and hang, realize salvaging.
Description of drawings
Fig. 1 is a structural representation of the present utility model
1 housing, 2 fuses, 3 suspension bodies, 4 centralizer bodies, 5 end caps, 6 sealing rings
The specific embodiment
The salvagable oil pipe overflow controller is provided with fuse in the housing, the fuse top is provided with end cap, and centralizer body passes end cap and is fixed together by suspension body and fuse.
Have groove on the inwall of housing, have through hole with the corresponding position of groove on the sidewall of fuse, suspension body passes through hole and is positioned at groove.Suspension body one end is processed into sphere, and the middle part is and the cylinder of ball with diameter that the other end is the cylinder bigger than middle part cylinder diameter.One end of suspension body sphere and the groove on the inner walls are complementary.
The diameter of centralizer body lower end is greater than the diameter of circular hole on the end cap.The centralizer body top is provided with the fishing head of umbrella.
Be provided with sealing ring between housing and the fuse.
The salvagable oil pipe overflow controller is with the tubing string G.I.H, and the supported and suspended body control of centralizer body suspension body, the spherical part of suspension body are suspended in the groove on the inner walls, fuse is suspended on the suspension body, sealing ring sealing fuse and housing stop the fluid passage, realize stopping up; Down to projected depth, fill flushing fluid in the oil pipe, carry the fishing head that fishing socket is salvaged centralizer body top with cable, rope, on carry, centralizer body breaks away from suspension body, suspension body loses constraint, carry in the continuation, centralizer body lower end pulling end cap and fuse, fuse begins up, groove on the inner walls produces radial component to the spherical part of suspension body, force suspension body inwardly to move, remove and hang, fuse trips out in well, remove and stop up, oil jacket is communicated with.
