摘要
对传统井壁稳定性和现场应用的利弊进行了分析 ,提出了一种更适用于现场钻后井壁稳定性分析的实用新方法。该方法根据钻井井史资料和声波测井资料 ,利用统计的方法揭示区域构造井壁稳定性规律 ,推荐合理的安全钻井液密度范围。该方法适用于钻后井壁稳定性分析和钻前井壁稳定性预测。
Wellbore stability is very important for fast and safe drilling. This paper estimates the advantages and disadvantages of conventional method for wellbore stability analysis and its onsite use, and presents a more practical method for wellbore stability prediction and post-drilling analysis on field. This method uses statistics in combination with drilling logs and sonic logging data, to disclose the tendency of wellbore stability. It is beneficial for determining suitable and safe mud density in drilling.
