Coupling-type multiplier

Abstract

The invention discloses a coupling-type multiplier capable of solving abrasion of an oil tube and a sucker rod. The coupling-type multiplier is mounted on the downhole sucker rod, moves up and down along with the sucker rod, and is in moving friction with the inner wall of the oil tube in a tightly attached mode; the oil tube is bent due to an oblique well, and under the upward tension action of an oil sucking machine, the coupling-type multiplier produces very high lateral pressure on the inner wall of the oil tube, therefore abrasion is very high; and because metal rings with small frictioncoefficients are embedded in the two ends of the coupling-type multiplier, the lubrication property can be effectively improved, so that abrasion is reduced to reduce frictional resistance, therefore,according to the coupling-type multiplier, the effects of reducing abrasion between the oil tube and the sucker rod and reducing the frictional resistance between the oil tube and the sucker rod whenthe coupling-type multiplier moves upwards along with the sucker rod are completed, and the purposes of reducing loss and increasing the production efficiency can be achieved.

Description

technical field [0001] The present invention is a coupling-type multiplier designed for reducing the consumption of oil production in the oil field, which can solve the wear problem between the downhole oil pipe and the sucker rod and is used in the oil well of oil exploitation. Background technique [0002] In the process of oil production, due to the well deviation of the oil well, the downhole oil pipe and the sucker rod are worn out due to friction, and frequent breakage accidents occur, which cause great losses to the oil production work in the oil field. How to solve this problem well is placed in the oil production The important issue before the workers, how to further reduce the loss, needs to be developed and applied urgently; [0003] Under the above circumstances, oil production workers traditionally adopt well repair and maintenance, which increases production costs, causes damage to oil wells, and causes considerable workload; the present invention is to solve t...
