Based on the comprehensive use of logging, pressure measurement, testing and other data, the abnormal pressure was identified, the pressure distribution characteristics and mudstone compaction mode were studied, and the causes of overpressure were analyzed. The results show that there is overpressure in the deep area of the study area, and the plane gradually changes from the north to the central area to overpressure, the pressure coefficient in the main depression area is 1.0 - 1.6, and the pre...
