Quantitative evaluation for hydrocarbon transport ability of faults connected with source rocks and relation with hydrocarbon accumulation:An example from E d~1 of Nanpu Depression

In order to study hydrocarbon accumulation of Ed1 in Nanpu Depression,based on the study of influence factors of the mechanism and ability of hydrocarbon transport,combined with the evaluation method of hydrocarbon transport ability of fault,the distribution of faults connected with source rocks and hydrocarbon transport ability of Ed1 in Nanpu Depression were studied.The result shows that there are a lot of faults connected with source rocks developed in Ed1.The hydrocarbon transport ability of faults connected with source rocks in Ed1 in Liuzan,Gaoshangbu,Laoyemiao,the east of Naupu 5 region,Nanpu 1 region,Nanpu 2 region and its eastern area,Nanpu 4 region and its southern area are stronger than that in other region,which is favorable for the hydrocarbon generated in Es3 or Es1-Ed3 source rocks migrated into Ed1 and accumulated there.At present,there are a large number of hydrocarbons found in theses areas,which proves the feasibility of this method to study hydrocarbon transport ability of faults connected with source rocks.
