Cover image by Yan Jin on pages 158-171. The image illustrates the process of wellbore instability analysis and control while drilling. A new method for wellbore instability analysis and control is proposed by combining image recognition methods with expert systems. The method applies an image recognition model improved by multi-source feature fusion to identify caving types and establishes an expert system model that correlates caving types with wellbore instability mechanisms.
