徐闻区块的机械钻速影响因素分析

Influential factors of mechanical drilling rate in Xuwen Block

徐闻区块地层可钻性差,机械钻速一直较低。徐闻X7井之前钻井平均机械钻速全部低于4m/h。本文针对钻井机械钻速的影响因素进行了分析,通过优选钻井参数,以期进一步提高机械钻速。

The Xuwen block has poor drillability and low rate of penetration. The average rates of penetration were less than 4 m/h in Xuwen X7 well. This paper describes the influential factors of the drilling rate of penetration to improve the mechanical drilling rate by optimizing the drilling parameters.
