摘要:

运用成藏动力学理论,在东营凹陷油气大规模成藏期古地温、古压力和古应力研究的基础上,分析了砂岩透镜体油气藏的动态成藏过程。研究结果表明,成藏动力贯穿于油气成藏的全过程,油气运移和聚集的原始动力是烃源岩内的流体异常高压;油气成藏的主控因素为烃源岩、输导体系和成藏动力;成藏动力学模式为应压双控、复合输导、幕式置换。

关键词: 砂岩透镜体油气藏, 成藏动力学模式, 应压双控, 复合输导, 幕式置换, 东营凹陷, 渤海湾盆地

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
