【摘要】 地层破裂压力在钻井施工、钻井液的选取及水力压裂等方面有着重要的意义。利用处理后的多极子阵列声波测井资料提供的准确的纵横波时差,结合岩石密度测井资料计算了岩石弹性力学参数、岩石强度参数,在此基础上进行了地应力分析,确定了地层破裂压力、钻井液密度等参数,同时预测了压裂高度,为油田的生产改造提供了准确的参数。更多还原

【Abstract】 Formation fracture pressure is vital to drilling operation, selection of drilling fluid,and hydraulic fracturing.Processed multi-pole array acoustic logging data can provide exact slow- ness of P-and S-waves.By combining with formatting density logging,we calculated parameters of rock elasticity and intensi- ty using multi-pole array acoustic logging,and performed for- rnation stress analysis to determine breakdown pressure and drilling fluid density.The fracturing height is also predicted. The resulted parameters provide accurate parameters for reser- voir reconstruction and oilfield production.更多还原
