Summary of the invention
The purpose of this utility model is inaccurate for injection well downhole flow regulator pulling, 5
1/
2〞 casing deformation or subsidize after, conventional injection well downhole flow regulator just can not, by the deficiency of the section of being out of shape and subsidizing sleeve pipe, provide a kind of eccentric injection mandrel.
For achieving the above object, the utility model adopts following scheme: a kind of eccentric injection mandrel, comprise top connection, adapter sleeve, connecting cylinder, main body and lower contact, adapter sleeve top is connected with top connection, adapter sleeve bottom is connected with connecting cylinder, connecting cylinder bottom is connected with main body, main body is connected with lower union joint, body shaft upwards offers eccentric orfice, inner major diameter is to being provided with the permeable sealing device being connected with eccentric orfice, permeable sealing device comprises sealing device and water permeable device, and sealing device is connected with water permeable device.
Sealing device comprises the closed hole of offering in main body, one end of closed hole is connected with eccentric orfice, and the closed hole other end is provided with plug, and plug is arranged in main body, in closed hole, be provided with the spring being connected with plug, be also provided with the valve seat, the ball that are connected with spring.
Water permeable device is the permeable hole of offering in main body.
The closed hole diameter of one end that closed hole is connected with eccentric orfice is less than ball diameter.
Valve seat is the conical surface that can fit with ball radian towards that one end of ball.
On plug, be provided with outage.
On adapter sleeve, be provided with fairlead, fairlead is eccentric openings structure, is provided with the guide way corresponding with fairlead in main body.
Guide way is symmetrical helicoid, and the helix intersection point center of symmetrical helicoid is provided with elongated slot.

The beneficial effects of the utility model: simple in structure, its fairlead and guide way, overcome the inaccurate problem of existing injection well downhole flow regulator pulling, can more conveniently extract, throw in blanking plug accurately; Diameter is little, has ensured the normal operation of casing deformation well and casing patch well, reduces the expense of well workover, increases work efficiency and crude output; The permeable sealing device arranging in injection well downhole flow regulator main body, all radially arranges, and is vertical relation with placing the fluid hole of blanking plug, and the outage on sealing device prevents that sand from entering eccentric orfice, shortens the life-span of blanking plug; Permeable sealing device plays permeable sealing function, and sealing device can prevent that the water injecting from flowing back in blanking plug again, damages blanking plug simultaneously; The valve seat arranging in sealing device, makes ball stressed more even, has extended the life-span of sealing device.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that A-A is to view.
Detailed description of the invention
A kind of eccentric injection mandrel, comprise top connection 1, adapter sleeve 3, connecting cylinder 5, main body 8 and lower contact 9, adapter sleeve 3 tops are connected with top connection 1, adapter sleeve 3 bottoms are connected with connecting cylinder 5, and connecting cylinder 5 bottoms are connected with main body 8, and main body 8 is connected with lower union joint 9, on main body 8 is axial, offer eccentric orfice 7, main body 8 internal diameters are upwards provided with the permeable sealing device being connected with eccentric orfice 7, and permeable sealing device comprises sealing device and water permeable device, and sealing device is connected with water permeable device.
Sealing device comprises the closed hole 15 of offering in main body 8, one end of closed hole 15 is connected with eccentric orfice 7, closed hole 15 other ends are provided with plug 10, plug 10 is arranged in main body 8, in closed hole 15, be provided with the spring 11 being connected with plug 10, be also provided with the valve seat 12, the ball 13 that are connected with spring 11.
Water permeable device is the permeable hole 14 of offering in main body 8.
The closed hole diameter of one end that closed hole 15 is connected with eccentric orfice 7 is less than ball 13 diameters.
Valve seat 12 is the conical surface that can fit with ball 13 radians towards that one end of ball 13.
On plug 10, be provided with outage.
On adapter sleeve 3, be provided with fairlead 2, fairlead 2 is eccentric openings structure, is provided with the guide way corresponding with fairlead 26 in main body 8.
Guide way 6 is symmetrical helicoid, and the helix intersection point center of symmetrical helicoid is provided with elongated slot.
