Exploration motor

Abstract

The invention discloses an exploration motor. The exploration motor comprises a shell, wherein one end of the shell is provided with a motor head; the upper end of the motor head is provided with a thrust sliding bearing component; the shell is also internally provided with a stator and a rotor; the stator is arranged sectionally; a sliding bearing is arranged between every two adjacent sections of the stator; the thrust sliding bearing component is sheathed on the rotor; the sliding bearing is ring-shaped and comprises a bearing inner ring and a bearing outer ring which are mutually matched; the bearing inner ring is arranged on the rotor, and the bearing outer ring is arranged on the shell; the thrust sliding bearing component comprises a thrust sliding bearing, a sliding plate, a positioning pin, a positioning ring and a half-opening ring. The exploration motor disclosed by the invention has the advantages that the stability and the high efficiency of operation can be maintained under the condition of bearing larger load, the energy is saved, the working efficiency is high and the service life is long.

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most oilfields have entered the middle and late stage of exploitation, and the method of self-injection oil recovery is no longer applicable to the current development plan of oilfields.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.
