Abstract
The utility model discloses a fixing type oil rod centralizing device, belonging to the improvement of an oil rod in an oil pumping machine used for the production of an oil field. Four arched bottom grooves which are uniformly arranged are arranged on a body surface which is fixedly provided with a hollow post shape body on the middle part of the outer wall of an auxiliary oil rod whose two ends are provided with threads. The middle part of two end surfaces of the hollow post shape body is two reinforcing dummy clubs. Two end parts of the hollow post shape body are arcs. The appearing of the fixing type oil rod centralizing device and the matching use with an oil rod can achieve the functions of the impact and abrasion resistance and the righting of the connecting hoop of the oil rod and a well wall, and a breaking phenomenon does not easily appear. A pump inspection period and the service life of the oil rod can be extended, and the oil exploitation rate of an oil well is enhanced. The utility model has simple structure, easy processing and production, and convenient use.
Description
The utility model belongs to the improvement of field produces with beam hanger in the oil pumper.
In the oil recovery manufacturing process in oil field, used oil pumper is the suction crude oil that pumps by its beam hanger.In use find to rub between the beam hanger and the borehole wall, be easy to occur disconnected holder phenomenon and the wearing and tearing of knot hoop, when beam hanger is stressed, can produce distortion.Its shortcoming is: shortened pump detection period, influenced tar productivity, reduced the application life of beam hanger.
The purpose of this utility model is the shortcoming at above-mentioned existence, and a kind of pump detection period that prolongs is provided, and increases the beam hanger device in application life.
The purpose of this utility model is achieved in that it is in the middle part of auxiliary beam hanger (1) outer wall of TBE (threaded both ends), be fixed with and have groove (5) at the bottom of four arches of even branch on the dignity of hollow cylindrical body (2), the both ends of the surface middle part of cylindrical body (2) is two reinforcement boss (4), and the both ends of cylindrical body are arc shape (3).It is to join for replacing screw thread with beam hanger.
Appearance of the present utility model with the supporting use of beam hanger, can reach the protecting against shock wearing and tearing and the centralizing function of the beam hanger knot hoop and the borehole wall, is not prone to disconnected holder phenomenon, can prolong the application life of pump detection period and beam hanger, improves the tar productivity of oil well.It is simple in structure, is easy to processing, and is easy to use.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A view of Fig. 1.
Cylindrical body of the present utility model (2) is to adopt high-strength nylon 6, is solidified to auxiliary beam hanger (1) middle part through injection machine thermalization injection moulding and makes.It and beam hanger connect into whole beam hanger for alternately tying hoop, are installed to the lifting position of oil pumper.
