摘要
目前预测地层破裂压力的方法很多, 多数方法中有些参数需经过大量的室内岩心试验获取。本文提出的是一种统计方法, 即通过统计水力压裂及套管鞋试漏数据直接绘制破裂压力与井深的关系曲线,并将其作为钻井工程设计及钻井液密度设计的依据, 可保证地层不被压裂,
A kind of statistical method to estimate formation fracture pressure is put forward in this paper, which can be directly used to draw the relationship curve of fracture pressure & well depth by use of recording hydraulic parting and casing shoe test leaking data. The curve can be used as the basis for drilling engineering, which can ensure no fracture to formation, and the field applications are also convenient.
