【摘要】 本文通过对现场大量钻头资料的统计分析,研究了压差和井深因素对钻速的影响规律,建立了适用于中原油田压差影响系数的计算模式。数据处理结果证明,维珠因和本尼得出的墨西哥湾地区的计算模式不适用于中原油田。更多还原

【Abstract】 The statistical analysis of the data from Zhongyuan Oilfield is conducted to study the effect of differential pressure on penetration rate. A calculating model applicable for Zhangyuan Oilfield has been presented in this paper. A comparison of the calculated results with this model and Vidrine-Benit’s model is given. It proved that the effect of differential pressure on penetration rate is related to the depth of well.更多还原
