本文介绍几个主要参数对钻速的影响,用简单数学式预算机械钻速、钻头工作时间、每只钻头进尺和成本,其结果与实际基本一致。通过井底压力差对钻速影响的分析,进一步说明泥浆排量、钻头压力降和当量泥浆循环比重在优选参数中合理匹配的重要性。 This article describes the impact of several key parameters on the rate of penetration, using a simple mathematical formula for calculating the rate of penetration, bit duration, footage per drill, and cost. The results are essentially the same. The analysis of the influence of the bottom hole pressure difference on the drilling speed further illustrates the importance of reasonable matching between the mud displacement, the bit pressure drop and the equivalent mud circulation proportion in the preferred parameters.
