Research on the micro-scale method for testing the mechanical anisotropy of shale

The mechanical anisotropy of shale is an important basic parameter for the study of in-situ stress, sidewall stability and hydraulic fracture propagation. In view of the limitations and low success rate for sample preparation in macro-scale tests, we chose clastic rocks and fragmentized blocks which...
