进一步提高导向钻井系统导向能力的关键是提高在整个斜井段复合钻进进尺的比例。应用加权残值法编制了导向钻具受力分析软件 ,并着重对复合钻进增斜力进行了初步研究 ,用理论研究的成果指导现场实践取得了较好的效果。在理论分析的基础上结合定向井、水平井井眼轨迹控制的实践介绍这项技术 The key to further improve the guiding ability of the steering drilling system is to increase the proportion of composite drilling footage in the entire inclined section. Applying the method of weighted residuals, the stress analysis software of the guide drill is compiled and the preliminary study on the increase of the inclined force of the composite drill is carried out. The results of the theoretical research have guided the field practice and achieved good results. Based on the theoretical analysis, we introduce the technology combining the practice of directional well and horizontal well trajectory control
