摘　　要：偏轴防斜钻具是一种新型的防斜钻具。分析了偏轴防斜钻具的工作原理 ,设计出了2 4 1 3mm井眼用偏轴接头 ,并优选了技术参数。研究设计的偏轴钻具组合在辽河油田进了现场试验 ,取得了明显的效果 ,控制了井斜 。Eccentric BHA is a new deflection controlling tool.The paper studied its deflection controlling mechanism.An eccentric shaft connection fitted 241 3mm well was designed, and its technology parameters was optimized. The eccentric BHA was carried out field-testing in Liaohe Oilfield. Good results have been gotten. Hole deflection was controlled and high drilling rate was also kept.
