Use of geological and seismic data

the hydrocarbon migration and accumulation are quantificational simulated by Basin2 in Dongying depression. The results as following: Lijin and Niuzhuang are sags of producing oil; The overpressure stratum of Dongying depression is mainly distributed in the stratum of lower of Shahejie Formation Ⅲ

Shahejie Formation Ⅳ and Kongdian Formation

the migration and accumulation time of the hydrocarbon fluid is at the Dongying Formation

and the period of Guantao Formation to Minghuazheng Formation. Overpressure distribution and the distribution of hydrocarbon accumulation zone with a certain degree of coupling relations. The area

which has low fluid potential should be favorable for pool-forming

is very important for later exploration.
