Abstract
The utility model relates to a protector for a fixed sensor of an oil extractor. The protector comprises a main body (3) and a spring (4). The protector is characterized in that the main body (3) has a cuboid channel steel cross-section structure, a center hole (B) is formed in the main body, two bosses (8) are arranged at each of two ends of the main body, a rectangular opening (C) is formed at the right end of the main body, and a spiral spring (4) is arranged on the upper part of the main body. The protector can prolong the service life of the fixed sensor, ensure the test of an indicator diagram, avoid well lying caused by sand blockage and the like due to long well stop time for replacing the fixed sensor, reduce the oil production cost, improve the oil well oil production time efficiency, and increase the crude oil yield.
Description
Technical field
the utility model relates to rod-pumped well test merit figure fixation of sensor resist technology, particularly is a kind of oil pumper fixation of sensor protective device.
Background technology
are in field produces, because rod-pumped well test merit figure uses fixation of sensor to be plastic material, between the upper and lower dish of the side's of being installed in clamp and polished rod eye.Under load change and other factor affecting, pumping pipe string can take place rotate release moment of torsion phenomenon, cause fixation of sensor to be damaged by torsion.In addition, in the influence of oil-extractor polish-rod fixation of sensor fluctuating load of slow following time, can occur being hit, the crimp phenomenon.Caused and can't test, need to shut down changed, and changed consuming time longly, caused the well of lying of reason such as sand card again easily, increased cost for oil production, rate when reducing well recovery influences crude oil production.
Summary of the invention
The purpose of
the utility model is exactly the above-mentioned defective that exists to prior art, and a kind of oil pumper fixation of sensor protective device is provided.
the utility model technical scheme comprises: main body and spring; The main body of its oil pumper fixation of sensor protective device is a cuboid channel-section steel cross-sectional configuration, is provided with centre bore above, and polished rod passes from centre bore; Two ends respectively are provided with two boss, insert on the polished rod eye to coil in the end face rectangular slot, and the main body right-hand member is provided with oblong openings; Fixation of sensor plug wire terminal is passed through; Top is provided with helical spring, is inserted in from polished rod, and spring top is by square clamp chucking polished rod.
The beneficial effect of
the utility model is: through using oil pumper fixation of sensor protective device; Can prolong fixation of sensor increases the service life; Guarantee indicator diagram measurement, avoid changing fixation of sensor and stop the well overlong time and cause reason such as the sand card well of lying, reduce cost for oil production; Rate when improving well recovery increases crude output.
