Novel exploration motor plain thrust bearing assembly

Abstract

The invention provides a novel exploration motor plain thrust bearing assembly which is characterized in that the novel exploration motor plain thrust bearing assembly comprises a positioning ring, arotor, a semi-opening ring, a sliding plate, a thrust sliding bearing and a positioning pin, wherein the sliding plate is located between the plain thrust bearing and the positioning ring, the plain thrust bearing is slidingly connected to the sliding plate, the sliding plate is screwed with the positioning ring, one end of the positioning pin is inserted into the plain thrust bearing, and the semi-opening ring is located between the rotor and the positioning ring. The novel exploration motor plain thrust bearing assembly has the advantages of simple structure and reasonable design, the stability performance of an exploration motor is greatly enhanced, the stability and high efficiency of operation can be maintained under the condition of a large load, and the service life is improved.

Description

technical field [0001] The invention relates to a motor, in particular to a direct thrust bearing device of an exploration motor for oil exploitation, and in particular provides a novel thrust sliding bearing assembly of an exploration motor. Background technique [0002] With the development of my country's petroleum industry, most oilfields have entered the middle and late stage of exploitation, and the method of self-injection oil recovery is no longer applicable to the current development plan of oilfields. The pumping unit is currently the most widely used oil extraction equipment, and it is also the main energy-consuming equipment in oil production, but its efficiency is low and energy consumption is large. According to statistics, the electric energy consumption of this kind of pumping unit accounts for about 1 / 2 of the oilfield exploitation cost, while the electric energy consumed by the beam pumping unit accounts for about 80% of the total electric energy. The low ...

At the same time, the pumping unit transmits power to the downhole deep well pump through the sucker rod. The length of the sucker rod in the downhole varies from several hundred meters to thousands of meters. , pipe leakage, etc., resulting in a high workload of pumping well operation and maintenance, and a high scrapping rate of pipes and rods

This not only reduces the production efficiency of the oil well, but also greatly increases the production cost of the oil field. The eccentric wear of the oil rod has become an important contradiction that restricts the efficient and stable production in the middle and later stages of oil field development.
