Abstract:
Based on the geological analysis of the carbonate rock formation in Shunbei oil and gas field, the reasons for the formation's easy wellbore instability are clarified: first, the rock is easy to be broken and the fracture develops, which is easy to have secondary fracture development, malignant leak...
