Abstract
The utility model discloses a well head water injection mandrel. The plug comprises a main body, a plug and a plug, wherein internal threads are arranged at two ends of the main body, a backwashing well channel and an injection water channel are arranged in the main body, a water outlet hole is formed in the side wall of the main body, the plug is screwed into the main body, a movable plug is sleeved on a small ball at the front end of the plug and seals the backwashing well channel, and the plug is arranged in the injection water channel. The plug consists of a fishing head, a body and a bottom plug, wherein the body is connected with the bottom plug by screw threads, and the water nozzle is tightly pressed at the connection part. The utility model has the advantages of simple structure, good sealing performance, easy field operation, quick plug replacement, capacity of allocating water at the well mouth and the like.
Description
The utility model relates to a kind of well head injection well downhole flow regulator, is applicable to oil field dispensing well water amount control.
All in well, water yield control, water nozzle pulling, allotment are all inconvenient for two sections used eccentric injection mandrels of (or multistage multistage) tubing string of present stage oil field dispensing well one-level, and success rate is low, has restricted the development of oil field well dispensing.And the blanking plug that the well head injection well downhole flow regulator must pull out earlier in the injection well downhole flow regulator when anti-flushing well just can carry out anti-flushing well, and it is very complicated to operate, and the plug structure complexity (having cam) in the injection well downhole flow regulator, requires great effort very much when dropping into or extracting blanking plug.
The purpose of this utility model is exactly the shortcoming that overcomes prior art, and a kind of well head injection well downhole flow regulator is provided.
The purpose of this utility model is achieved in that the well head injection well downhole flow regulator is made up of main body, plug, blanking plug, there is internal thread at the main body two ends, have the anti-flushing well passage in the main body and inject aquaporin, have weep hole on the sidewall of main body, plug screws in the main body, be with movable drain plug on the front end bead of plug, movable drain plug sealing anti-flushing well passage injects aquaporin blanking plug is housed.
Blanking plug is by fishing head, body, the stifled composition of the end, and the body and the end are stifled by thread connection, and mouthpiece is being pressed in the connection place.
The utlity model has simple in structure, good seal performance, execute-in-place easily, change blanking plug quick, can carry out advantage such as water yield allotment at well head.
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1: the utility model structural representation;
As shown in Figure 1, the well head injection well downhole flow regulator is made up of main body 2, plug 1, blanking plug, there is internal thread at main body 2 two ends, have the anti-flushing well path 10 in the main body 2 and inject aquaporin 11, have weep hole 5 and 7 on the sidewall of main body 2, plug 1 screws in the main body 2, be with movable drain plug 3 on the front end bead of plug 1, between plug 1 and the movable drain plug 3, adopted ball face sealing, it can be sealed by automatic capturing.Movable drain plug 3 sealing anti-flushing well path 10s inject aquaporin 11 blanking plug are housed.
Blanking plug was made up of fishing head 4, body 6, the end stifled 9, and body 6 leans on thread connection with the end stifled 9, and water nozzle 8 is being pressed in the connection place.Whole blanking plug does not have cam, and its degree of depth that enters injection well downhole flow regulator injection aquaporin 11 is limited by the step on the injection well downhole flow regulator body 6.
During water filling, because the anti-flushing well path 10 is shut by movable drain plug 3, current can only enter in the blanking plug body 6 through aperture, the water nozzle that injection aquaporin 11, the end are blocked up on 10, enter waterflood-transmission line from weep hole 7 again, form water filling, because the blanking plug fishing head presses closer on the right plane of plug, so when high pressure water injection, whole blanking plug can not got excited by High-Pressure Water.When the need anti-flushing well, rotate counterclockwise plug 1 a few, (this moment, plug 1 still sealed injection well downhole flow regulator main body 2) drives the inner conical surface that movable drain plug breaks away from injection well downhole flow regulator main body 2, opens the anti-flushing well path 10, and the anti-flushing well current flow out from the anti-flushing well path 10 through water injection pipe, weep hole 5.Backwash finishes, and clockwise rotates plug 1 again, and plug 1 heads on movable drain plug 3 and moves forward, when movable drain plug 3 contacted with injection well downhole flow regulator main body 2 inner conical surfaces, it can freely swing under the effect of ball, carried out centering automatically, make its sealing anti-flushing well path 10, from then on injection water current are flow through.
When pulling blanking plug or replacing, allotment water nozzle 8, only need bar up waterflood-transmission line well head injection well downhole flow regulator two gate, unload plug 1 and movable drain plug 3, with special-purpose deliver to drag for carry or transfer blanking plug on the fishing head 4 and can finish.
