Abstract
The utility model relates to an oil extracting worker journey layering water injection technology field, in particular to divide compensator for water injection well. The cover is equipped with the sealing ring in the device's the top connection, and sealed through installing at the inboard sealing washer of sealing ring between top connection and the sealing ring, end screw thread connection is on the sealing ring outer wall on the hydraulic cylinder, and hydraulic cylinder lower extreme and outer wall of the lower joint threaded connection are equipped with spacing step on the outer wall of top connection upper end, and threaded connection has a cap fully on the top connection lower extreme outer wall, the sealing ring can spacing step with be equipped with between the cap along the removal of top connection outer wall. The utility model discloses a simple structure, convenient operation, it is flexible to compensate oil pipe length, prevents oil pipe's flexible injury to lower part tubular column cluster, the security that improves the seperated layer water injection work progress. It is complicated to have overcome current water injection pipe compensator structure, operates inconvenient not enoughly.
Description
Technical field:
This utility model relates to petroleum production engineering separate zone waterflooding technology field, mends particularly to a kind of dispensing well
Repay device.
Background technology:
Liaohe Oil Field has high-pressure water injection well more than 300 mouth at present, accounts for the 8% of water injection well sum.Because interlayer pressure difference is big,
Water filling or stop the reasons such as note and easily cause tubing string and elongate or shorten, causes separate injection tubing string to lose efficacy.Existing water injection pipe
Compensator structure is complicated, inconvenient operation.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of dispensing well compensator, and this device realizes
Simple in construction, easy to operate, it is possible to compensate tubing length and stretch, prevent the flexible to bottom tubing string of oil pipe
The injury of string, improves the safety of seperated layer water injection work progress.Overcome existing compensator for water injection pipe structure multiple
Miscellaneous, the deficiency of inconvenient operation.
Technical solution adopted in the utility model is: a kind of dispensing well compensator, including top connection and under
Joint；Sealing ring it is set with, by being arranged on inside sealing ring between top connection and sealing ring in top connection
Sealing ring seals, and fluid cylinder threaded upper ends is connected on sealing ring outer wall, fluid cylinder lower end and lower contact outer wall thread
Connecting, top connection upper end outer wall is provided with limited step, and threaded on top connection lower end outer wall have standby cap,
Sealing ring can move along top connection outer wall between limited step and standby cap.
The beneficial effects of the utility model are: this utility model simple in construction, easy to operate, it is possible to compensate oil
Length of tube stretches, and prevents the flexible injury to bottom tubing string string of oil pipe, improves seperated layer water injection work progress
Safety.
Accompanying drawing illustrates:
The utility model is described in more detail with detailed description of the invention below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
As it is shown in figure 1, a kind of dispensing well compensator, including top connection 1 and lower contact 5；Top connection 1
On be set with sealing ring 2, by being arranged on the sealing ring inside sealing ring 2 between top connection 1 and sealing ring 2
Sealing, fluid cylinder 3 threaded upper ends is connected on sealing ring 2 outer wall, fluid cylinder 3 lower end and lower contact 5 outer wall spiral shell
Stricture of vagina connects, and top connection 1 upper end outer wall is provided with limited step, and threaded on top connection 1 lower end outer wall have
Standby cap 4, sealing ring 2 can move along top connection 1 outer wall between limited step and standby cap 4.
When tubing string stretches, sealing ring 2, fluid cylinder 3 are integrated with lower contact 5, can be in the limit of top connection 1
Slide between position step and standby cap 4, play compensating action.
It is understood that above with respect to specific descriptions of the present utility model, be merely to illustrate this utility model
And it being not limited to the technical scheme described by this utility model embodiment, those of ordinary skill in the art should
Work as understanding, still this utility model can be modified or equivalent, to reach identical technique effect；
Needs are used, all within protection domain of the present utility model as long as meeting.
