Abstract: The reconstruction of paleo-sedimentary thickness and paleo-formation pressure isvery important indeed in studying the history of the basin's evolution, hydrocarbon exploration, migration and accumulation. According to the data of mudstone coustic time of DNBasin, normal-compaction trend lines of single formation pore-depth and pore-time wereset up by application of mudstone compaction irreversible principle, and the reconstructionmethod of paleo-sedimentary thickness and paleo-formation pressure in a abnormal highpressure region was derived in this paper. Finally the author used this method to analysethe mechanism and time of the pressure formation and the condition of hydrocarbon accumulation and migration.
