| 摘 要： | 水力压裂高度预测,对试油和储层改造都有非常重要的作用。本文通过地层强度参数、地层闭合压力(一般来说是最小水平应力)和岩石破裂特性计算出应力强度因子和岩石韧度来获取地层压力剖面和裂缝高度。同时运用破裂点最小水平应力与加压值之和与预测点最小水平应力相比较的方法来预测射孔层段压裂缝高度.将这些方法应用到实例中,达到了预期的压裂效果。

| Abstract: | Prediction of hydraulic fracture height plays an important role in oil testing and reservoir reconstruction.Formation pressure profile and fracture height can be obtained by calculating stress intensity factor and rock tenacity with the parameters of formation strength, formation closing pressure (generally the minimum horizontal stress )and rock burst characteristics.Meanwhile the hydraulic fracture height of perforated zone is predicted by comparing the sum of the minimum horizontal stress of breakpoint a... |
