摘要:

依据测井资料对安棚碱矿地层自然漂移规律统计分析,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,提出了井口坐标设计方案.经实际应用,缩短了钻井周期,提高了钻机月速及机械钻速.

Abstract:

The natural drift law on the formation in Anpeng Alkaline Mine is analyzed by statistics based on the actual well logging information. The natural drift law is used to design the borehole profile. The planning of the well coordinate is present using regressive theory and correlation equation between horizontal displacement and true depth. The practice showed the using the method can shorten total drilling time and increase ROP.
