Fitting of anisotropic strength parameters of laminated shale and its influence on wellbore instability

Abstract To understand the intrinsic causes and influencing factors of shale wellbore instability, the anisotropic mechanical properties of layered rocks is analyzed. Using the existing strength test data of shale with different bedding angles, the variation characteristics of rock strength with bed...
