الوصف: Composite salt formation is a high-quality caprock for oil and gas resources. The accident encountered in composite salt formation drilling is a big problem to be solved in the drilling process. According to statistics, nearly 50% of drilling accidents occur in composite salt formations. The composite salt formation is mainly composed of salt, gypsum, and interbed mud, and the lithology is complex and changeable. Therefore, it is very important to study the deformation mechanism and leading influencing factors of composite salt formation in view of the problem of frequent accidents in the drilling process. In this article, the creep parameters based on the constitutive equation of creep of salt rock are obtained by combining theoretical with experimental research. A three-dimensional directional wellbore mechanical model is established to analyze the influence of inclination on borehole shrinkage.
