13000 m大深度绳索取心绞车关键技术研究
Research on key technologies of 13000 m wireline coring winch
摘要
Abstract
To address the challenge posed by the lack of domestically manufactured wireline coring equipment for ultra-deep scientific drilling exceeding 10000 m in China,a design study on a 13000 m deep wireline coring winch was conducted.Considering complex working conditions such as the piston effect induced by narrow annular clearance and caused by borehole deviation friction,a mechanical model for wire rope hoisting was established.Numerical simulation was performed to quantify the peak load of the wire rope under different accelerations,determining a safe operating range with a starting acceleration of 0.1 m/s² and a maximum constant hoisting speed of 1 m/s.Accordingly,the core technical parameters were determined,including a rated traction force of 200 kN,a rope storage capacity of no less than 14500 m,a wire rope diameter of 17.3 mm,and a wire rope grade of 2160 MPa.An integrated structure combining a tension-reducing traction winch and a storage winch was proposed.A master-slave synchronous drive system with dual friction drums was designed,incorporating a slack compensator,PID-based constant tension control,and automatic spooling technology to achieve orderly winding and tension buffering of the wire rope.A distributed electrical control system based on the Profinet bus was developed to ensure precise operation.The results indicate that the proposed design can effectively reduce the winding tension of the wire rope,mitigate issues of disorderly spooling and associated wear,and improve control accuracy,thereby meeting the requirements for safe and continuous coring in ultra-deep wells.This study provides key technical support for the localization of deep earth exploration equipment in China.关键词
