Abstract
The utility model discloses a water flow regulator core for well water injection in oil field, which comprises a main body (1) and seal rings (2). The main body (1) is configured to be a tapered cylinder and is provided with a group of step-shaped ridges on the cylindrical surface with smaller diameter, each ridge with a reduction from the exterior width to the interior width. The cross section of each seal ring (2) is composed of an outer semicircle and an inner rectangle, in which the semidiameter of the outer semicircle is smaller than the width of the inner rectangle. The seal rings (2) are arranged inside the step-shaped ridges to prevent from falling out during casing and fishing processes. A group of seal ring grooves are arranged on the cylindrical surface with smaller diameter of the main body (1), so as to move upwards a step of a limiting core on an inner hole of a central tube of the water flow regulator and thus to allow an increase in diameter of an inner hole of the step, thereby facilitating both casing/fishing test and machining of central tube of the water flow regulator.
Description
One, technical field:
The utility model relates to a kind of water distributor core, is applicable to oil field well water filling, particularly is a kind of fuse that is used with water filling instrument hollow distributor.
Two, background technology:
The oil field is in water filling, and there are 2 deficiencies in the hollow distributor fuse of former usefulness: (1) fuse sealing ring in removing pulling easily comes off, and influences flood effectiveness; (2) though main body is up big and down small, the groove of fitting tight circle designs on major diameter, causes the step aperture of injection well downhole flow regulator central tube endoporus upper limit fuse less, so both has been unfavorable for dropping-fishing test, has brought difficulty for again the processing and manufacturing of injection well downhole flow regulator central tube.
Three, summary of the invention:
The purpose of this utility model is: a kind of water distributor core is provided, prevents effectively that not only sealing ring from coming off, and help dropping-fishing test, make the processing and manufacturing of injection well downhole flow regulator central tube easy again.
The utility model is achieved in that water distributor core is made up of main body and sealing ring, the cylindrical of main body is the up big and down small face of cylinder, the protruding step groove that narrow inner width outside a group is arranged on the face of cylinder of minor diameter, the outside, cross section of sealing ring is semicircle inner be rectangle and outer narrow inner width, sealing ring is assemblied in the protruding step groove of main body, the rectangle step of sealing ring inner width matches with the protruding step groove of main body inner width, so sealing ring is difficult for deviating from pulling; Design has one group of seal groove on the small diameter cylinders face of main body, can make on the step of the injection well downhole flow regulator central tube endoporus upper limit fuse that is mated and move, the diameter of bore of its step can be bigger than original with designing, so both helped dropping-fishing test, is convenient to the processing and manufacturing of injection well downhole flow regulator central tube again.
Four, description of drawings:
Accompanying drawing 1 is a structure chart of the present utility model.
Accompanying drawing 2 is a partial enlarged drawing of the present utility model
Among Fig. 1,2,1-main body, 2-sealing ring
Five, embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is further elaborated:
The utility model is made up of main body (1), sealing ring (2), the cylindrical of main body (1) is the up big and down small face of cylinder, the protruding step groove that narrow inner width outside a group is arranged on the small diameter cylinders face, the outside, cross section of sealing ring (2) is semicircle inner be rectangle and outer narrow inner width, sealing ring (2) is assemblied in the protruding step groove of main body (1), the rectangle step of sealing ring (2) inner width matches with the protruding step groove of main body (1) inner width, so sealing ring is difficult for deviating from pulling; Design has one group of seal groove on the small diameter cylinders face of main body (1), can make on the step of the injection well downhole flow regulator central tube endoporus upper limit fuse that is mated and move, the diameter of bore of its step can be bigger than original with designing, so both help dropping-fishing test, be convenient to the processing and manufacturing of injection well downhole flow regulator central tube again.
Claims (1)
