Abstract

Abstract:

Based on research of the palaeogeothermal,palaeopressure,and palaeostress during large scale hydrocarbon accumulation in Dongying sag,the dynamic hydrocarbon accumulation in sand lens reservoirs is analyzed by applying the theory of reservoiring dynamics.The results show that resevoring dynamics run through the whole process of hydrocarbon accumulation and the overpressure of fluids in source rocks is the primitive drive for hydrocarbon migration and accumulation.According to the research,the main factors that control hydrocarbon accumulation are source rock,carrier system and reservoiring dynamics,and the pattern of reservoiring dynamics is dual control of stress and pressure,duplex conduction,and episodic replacement.

Key words: sand lens resevoir, reservoiring dynamics pattern, dual control of stress and pressure, duplex conduction, episodic replacement, Dongying sag, Bohai Bay basin
