摘要
利用现场测井资料和真三轴岩石力学实验得到的岩石力学参数,结合库伦摩尔准则和地应力分析,获得该地区三压力剖面曲线,由此取得安全钻井液密度窗口。在现场应用中取得了良好的效果。
Using log data from the field and rock mechanics parameters from rock mechanics experiments, and combining with analysis of the wellbore rock stress state and the Mohr-Coulomb failure criterion, three pressure profiles of wellbore stability will be calculated, then the safe drilling fluid density window will be determined.According to analysis ofTahe oilfield formation characteristics. When applying this density window to field, we find that this study have a good application result.
