Title: Different types of overpressured reservoirs and their implications of hydrocarbon accumulation in Dongying depression
Abstract: The overpressure commonly existed in Dongying depression reservoir mainly consists of 2 types: neighbor sourced overpressure and allogenic sourced overpressure.Hydrocarbon-bearing abundance of those reservoirs,where neighbor sourced overpressure is only related with compaction of surrounding mudstone,varies largely.The neighbor sourced overpressure,which is related to the hydrocarbon-generating overpressure of surrounding mud stone,indicates the significant hydrocarbon accumulation.Faults connected with source rocks are material and energy conduits of overpressured hydrocarbon-generating fluids migrating from deeper source rocks.Allogenic overpressured areas near the faults connected with source rocks are favorable dynamic traps.
