  ABSTRACT: 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 pressure coefficient in the eastern area is 1.0 - 1.2; the mudstone index compaction mode is the most common compaction mode, the mudstone in the eastern part of the study area is the common exponential compaction mode, the mudstone in the main depression area is different from the common exponential compaction mode, showing two-stage characteristics, which is a linear two-stage compaction mode; the eastern and main depression areas of the study area are fluid expansion/Pressure conduction causes overpressure.
