Abstract
The utility model relates to a pumping rod centralizer used for an oilfield horizontal well, in particular to a sand rotating and centralizing pipe nipple of a pumping rod, which comprises an upper pumping rod joint, an upper sand rotating device, a centralizing device, a central pipe, a lower sand rotating device and a lower pumping rod joint. The pumping rod centralizer is characterized in that the upper pumping rod joint is connected with the upper sand rotating device by a screw thread; the centralizing device is sleeved on the central pipe which is arranged between the upper sand rotating device and the lower sand rotating device, and the lower sand rotating device is connected with the lower pumping rod joint by a screw thread. The utility model can effectively solve the problems of friction of the pumping rod and an oil pipe and sand burying, and prolong the service life of the pumping rod and the oil pipe.
Description
Technical field
The utility model belongs to the oilfield horizontal well oil pumping rod centering device, and particularly a kind of sucker rod revolves the sand centering short segment.
Background technology
At present, conventional oil pumping rod centering device can not solve horizontal well sand and bury problem.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of sucker rod to revolve the sand centering short segment, this centering short segment connects two upper and lower sand devices that revolve by upper and lower two rod connectors, connect a centralizer again, when the upper and lower motion of sucker rod, the upper and lower sand device that revolves rotates, and sand is together flowed with well liquid, oil pipe does not contact with rod collar, does not produce friction and sand and buries.
The technical scheme in the invention for solving the technical problem is: a kind of sucker rod revolves the sand centering short segment, by last rod connector, on revolve sand device, erection device, central tube, backspin sand device and lower sucker rod joint and form, its special character is: go up rod connector with revolving the sand device on being threaded, erection device is enclosed within on the central tube, central tube revolves between the sand device upper and lower, and backspin sand device is with the lower sucker rod joint that is threaded.
The beneficial effects of the utility model are: can solve sucker rod and oil pipe friction and sand effectively and bury problem, prolong the application life of R a T.
Description of drawings
Accompanying drawing is a schematic diagram of the present utility model.
In the accompanying drawing: 1, go up rod connector 2, on revolve sand device 3, erection device 4, central tube 5, backspin sand device 6 lower sucker rod joints
The specific embodiment
