Description
Technical Field
The utility model belongs to the technical field of viscous crude well is annotated and is adopted, especially relate to an annotate and take out rotatory centralizer.
Background
At present, in the process of injection and production integrated oil extraction operation, a sucker rod moves in an oil pipe, friction is easily generated between the rod and the wall of the oil pipe due to elastic deformation of the sucker rod, the sucker rod is easily broken and separated, a conventional sucker rod centralizer is connected to the sucker rod, the outer diameter of a centralizing sleeve is larger than the outer diameter of a sucker rod coupling to play a role in centralizing, and the centralizing sleeve is contacted with the oil pipe to achieve the purpose of preventing the eccentric wear of the sucker rod;
in the conventional centralizer, there are the following problems;
although the eccentric wear of the sucker rod can be reduced in the operation process of the centralizer, the service lives of an oil pipe and the centralizer can be influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a rotatory centralizer is taken out to notes to solve current problem: although the eccentric wear of the sucker rod can be reduced in the operation process of the centralizer, the service lives of an oil pipe and the centralizer can be influenced.
In order to solve the technical problem, the utility model discloses a realize through following technical scheme: a rotary centralizer for injection and extraction comprises a centralizer main body, wherein the centralizer main body consists of a conversion joint, a fixing screw, a rotating body and a connector;
a rotating body is arranged at the bottom of the adapter, and a fixing screw is arranged on one side of the adapter;
the inside of the rotating body is also provided with a connector;
and the adapter and the connector are respectively connected with an upper sucker rod and a lower sucker rod inside the tubing string.
Furthermore, the periphery of the rotating body is provided with a spiral channel, the diameter of the channel is 6mm, and the rotating body is pushed to rotate when steam is injected.
The utility model discloses following beneficial effect has:
the utility model discloses a sliding friction between crossover sub and the rotator changes rolling friction into, prolongs the life of oil pipe column, sucker rod, centralizer to extension workover cycle improves the efficiency of gathering, reduces the operating cost.
