沉积盆地中的地应力张量可以从油气勘探威尔斯井的钻井和测井过程中收集的信息中推断出来。主应力大小可以从密度测井、钻井历史、泄漏测试结果和孔隙压力测量提供的信息中获得。水平主应力方向由四臂地层倾角测井记录的钻孔崩落指示。应力大小估计值与水力压裂获得的值相当，方位数据提供了迄今无法获得的详细程度。所获得的信息有助于设计水力压裂、二次开采方案和获得最佳钻头性能。它还有助于了解岩石圈板块运动、地壳沉降和构造变形。
Abstract Estimates of the in situ stress tensor in sedimentary basins can be inferred from information gathered during the drilling and logging of hydrocarbon exploration wells. Principal stress magnitudes can be obtained from information provided by density logs, drilling histories, leak-off test results and pore pressure measurements. Horizontal principal stress orientations are indicated by borehole breakouts recorded on four-arm dipmeter logs. The stress magnitude estimates are comparable with values obtained from hydraulic fracturing and the orientation data provide a level of detail hitherto unobtainable. The information obtained assists in designing hydraulic fractures, in secondary recovery programmes and in obtaining optimum drill bit performance. It also contributes to understanding lithospheric plate movements, crustal subsidence and tectonic deformation.
