滑动式导向钻具组合复合钻井导向力计算及影响参数

Calculating the Steering Force of the Compounding Slide Steering Assembly and Its Main Influence Parameters

对连续导向技术中的复合钻井技术进行了研究 ,提出了复合钻井时的导向力计算方法 ,并对主要因素的影响规律进行了研究。结果表明 ,较好地设计钻具组合的结构 ,可以得到令人满意的导向力。为了确保作业的安全性和得到较好的井眼轨迹控制效果 。

The compounding slide steering drilling mode of this technology was studied and the method calculating the steering force of the slide steering assemblies was brought forward in this paper. The influence of the main parameters was also studied. The results show that by designing the structure of the slide steering BHA carefully, an appropriate steering force can be gained. For the safety of drilling practice and a good control of well trajectory, the bending angle of down hole motor should be selected carefully.
