摘要
自动垂直钻井系统是一种能够自动有效控制井斜、保证钻头始终沿垂直方向钻进的机电液一体化集成钻井装置,可有效解决高陡构造地层防斜打快问题。以胜利石油管理局钻井工艺研究院自主研发的捷联式自动垂直钻井系统为背景,对其稳定平台的结构和工作原理进行分析,在钻进和纠斜2种不同的工作模式下稳定平台采用不同的控制结构,并在Ansoft/Simplorer环境中建立了控制系统的仿真模型。仿真分析结果表明,所设计的控制方法动态跟踪特性良好,稳态偏差较小,具有较强的抗干扰特性,为捷联式稳定平台控制系统的进一步开发和优化提供了理论基础。
The automatic vertical drilling system is a hydromechatronics integrated device,which automatically keeps the drill bit to drill vertically for controlling well deviation,it is the developing trend of controlling wellbore inclination.Based on the strap-down automatic vertical drilling system developed by Shengli Drilling Technology Research Institute,this paper analyzed the structure and principle of the stabilized platform,and established two different controlling methods according to the working modes both usual drilling and controlling of well inclination respectively.An simulation model for control system has been established by means of Ansoft/Simplorer,the results show that the design has a good dynamic tracking features,small steady-state error and strong anti-jamming.The research of this paper provides a theoretical basis for further developing the stable platform with strap-down control system.
