摘要
本文提出了利用水力压裂、密度测井、实验室岩心分析、油田开发过程中实测地层温度和地层孔隙压力资料计算就地三向主应力和构造应力大小的新方法,与公认的海姆森法相比,考虑因素更全面,因而计算结果更精确。
Abstract
This paper introduces a new method for calculating the in-situ three-dimensional principal stress and structural stress using the data of hydraulic fracturing,density logging,laboratorial core analysis,and the measured temperature and pressure of formation in the oilfield development.Compared with the Heymans method,it considers the more factors,and then the Calculated results are more accurate.
