曙古11水平井定向造斜段钻具组合导向能力计算分析

Analysis of steering ability of BHA in build up section of horizontal well Shugu 11

利用平衡侧向力方法和SABHA软件系统,对曙古11水平井定向造斜段钻具组合的导向能力进行了预测分析。结果表明,这种方法具有很高的预测精度。通过优化双稳定器滑动导向钻具组合的结构参数,可以获得较单稳定器滑动导向钻具组合更高的导向能力。

The steering ability of BHA in build up section of horizontal well Shugu 11 has been predicted and analyzed by balanced side force method and SABHA software. The result shows that this method has high accuracy. Comparing with single stabilizer slide - and -guide BHA, a better steering ability can be achieved through optimizing the structure parameters of double stabilizer slide - and - guide BHA.
