ABSTRACT:
In recent years, the global demand for oil has been increasing. In order to reduce production costs, horizontal drilling technology is basically used for deep oil storage, so a cable-driven downhole towing system (horizontal well tractor) has emerged. The traditional horizontal well tractor drive motor has large volume, low efficiency, high vibration and noise, and cannot meet the requirements. Therefore, a permanent magnet synchronous motor with small size, light weight and high efficiency is proposed as the horizontal well drive motor. The paper discusses the coordinate transformation and mathematical model of permanent magnet synchronous motor, analyzes the working principle of permanent magnet synchronous motor vector control technology, and establishes a permanent magnet synchronous motor vector control simulation model using MATLAB simulation software. The simulation results verify that the control system has fast response speed and strong anti-interference, and meets the working requirements of horizontal well tractors.
