摘　　要：为分析超深侧钻井井眼环空净化状况,给现场钻井施工提供指导,结合国内外研究成果,用最小排量分析井眼净化情况,计算出岩屑床高度。同时提出安全排量概念。利用安全排量计算系统压耗,依据系统压耗分析泥浆泵能力,为超深长位移侧钻井的可行性论证提供了一种分析方法。To analyse the hole-cleaning condition of mega-deep-long-reach sidetracking well and provide guid- ance during drilling, combining research results at home and abroad, min-flowrate is proposed to study the hole cleaning condition and a approach is used to calculate the bed height. Safety flowrate is proposed, it is used to cal- culate the system pressure loss and the system pressure loss is utilized to study the ability of mud pump. A new ana- lysing approach is proposed to decide the feasibility of mega-deep-long-reach sidetracking well from the theory of drilling hydraulics.
