摘　　要：定向钻进技术目前被广泛应用于煤层气的开采中。为了提高煤层气开采的质量和效率,必须提高煤层定向钻进过程的智能化水平。通过煤层定向钻进的三维离线编程系统,获取钻进轨迹的控制参数,并利用该系统自动生成的钻具控制程序,钻进过程中根据设计钻进轨迹与实际的钻进轨迹的偏差进行自动纠偏,从而实现煤层定向钻进的智能化。Directional drilling is one of the high-tech in CBM.In order to implement scientific development and utilization,increase the quality and efficiency of CBM exploitation,it is necessary to improve the intelligent level of the directional drilling process.Through the three-dimensional off-line programming system of coalbed directional drilling,the control parameters of the drilling trajectory are obtained and the drilling control program is automatically generated.At the same time it can rectify according to the deviation between actual track and designed one automatically to achieve intelligent control during directional drilling.
