exploration motor

Abstract

The invention discloses an exploration motor, which comprises: a casing, a motor head is arranged at one end, a thrust sliding bearing assembly is arranged at the upper end of the motor head, a stator and a rotor are arranged in the casing, and the stator is divided into two parts. Sliding bearings are arranged between two adjacent stators, and the thrust sliding bearing assembly is set on the rotor; the sliding bearing is ring-shaped, and the sliding bearing includes a bearing inner ring and a bearing outer ring that cooperate with each other. The bearing inner ring is installed on the rotor, and the bearing outer ring is installed on the housing; the thrust sliding bearing assembly includes: a thrust sliding bearing, a slide plate, a positioning pin, a positioning ring, and a half open loop. The exploration motor of the present invention can maintain the stability and high efficiency of operation under the condition of bearing relatively large compounding, and it saves energy, has high working efficiency and long service life.

Description

technical field [0001] The invention relates to a motor, in particular to a prospecting motor for oil exploitation. 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most oilfields have entered the middle and late stage of exploitation, and the method of self-injection oil recovery is no longer applicable to the current development plan of oilfields.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 operating efficiency of the above-mentioned pumping units is a common phenomenon. For example, the average operating efficiency...

[0003] 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.
