[Abstract]:This paper analyzes and studies the existing seismic source unlocking devices at home and abroad, combined with the current situation of logging operations in China, in view of the pulse downhole seismic source system exploration and recovery process. A set of active safety release device for seismic source in deep well exploration has been developed. By deducing that the safety pin of the connecting rod can release the pushing part of the tool from the shaft wall, the safe lifting device can be used to reduce the unnecessary economic loss of the logging company and the oil field. According to the requirements of the active safety de-card device working in the high temperature environment, in this paper, from the power electronic switch circuit and armature winding form, permanent magnet brushless DC motor body. Rotor excitation structure, circuit and rotor position sensor, etc., to determine the design scheme of brushless DC motor for card device, through the analysis and study of the structure and principle of permanent magnet brushless DC motor. According to the design method of permanent magnet brushless DC motor, the main dimensions of motor, permanent magnet size and magnetic circuit are calculated in turn. The brushless DC motor is designed with high temperature resistant permanent magnet material and electromagnetic material. Secondly, this paper analyzes the key points and difficulties in the design of the transmission system of the card device. Combined with the knowledge of mechanics and mechanical design, the paper considers the safety of operation, the stability of operation and the way of connection, and puts forward the design scheme of the transmission system of card device. And the main components of the driving system of the card unlocking device-deceleration device, coupling and ball screw are designed and selected. Thirdly, aiming at the characteristics of high temperature in the working environment of the active safety unlocking device of the seismic source. Through the single chip microcomputer HT83C51 control part, the rotor position signal detection and processing circuit, the switch main circuit and the gate drive circuit design. The design of PWM duty cycle given circuit, soft start circuit, current limiting circuit and protection circuit, complete the design of the hardware and reliability of the card device control circuit, realize the start / stop control of the card device. The ejection / retraction of the card unlocking device and the steady speed control of the motor. Finally, the experimental research on the prototype of the card unlocking device is carried out. The feasibility and maneuverability of the designed active safety card unlocking device for seismic source in deep well exploration are verified. Through hard work, the device meets the relevant technical requirements and can realize the active safety card release of the seismic source instrument.
