结合江苏油田导向钻井技术现场试验中采用的三种典型的滑动导向钻具组合 ,在计算复合钻井导向力的基础上 ,探讨了两个主要因素对复合钻井导向力的影响规律。结果表明 ,理论计算结果与现场试验结果基本吻合 ,通过设计钻具组合的结构和施工参数 ,可以提高井眼轨迹控制精度 Combined with the three typical sliding guide assemblies used in the field tests of the pilot drilling technology in Jiangsu Oilfield, the influence laws of the two main factors on the composite drilling guide force are discussed based on the calculation of the composite drilling guide force. The results show that the theoretical calculation results are in good agreement with the field test results. By designing the structure and construction parameters of the drilling assembly, it is possible to improve the accuracy of well trajectory control
