摘要: 通过对安棚碱矿地层自然漂移规律的研究,依据实钻测井资料统计分析,进行井身剖面设计,并运用回归理论确定水平位移与垂直井深相关方程,提出了安棚碱矿地层方位、井斜自然漂移规律和井口座标优选设计方案,并据此应用了4口井,取得了平均单井钻井周期减少47.15%,行程钻速提高86.95%,机械钻速提高47.00%的好成效。Abstract: The n atural drifting pattern of trajectory in formations in Anpeng alkali mine is stu died.Well profile is designed based on statistics of logging data.Relational e quation be-tween horizontal displacement and vertical depth is estab-lished b y using regression theory.This paper presents the formation azimuth,natural dr ifting pattern in formations and optimal design of wellhead coordination.It has been ap-plied in4wells with the averaged single well drilling cycle reduced4 7.15%,drilling rate of a trip increased86.95%,and penetration rate increased47.00%.
