摘要: 针对岩性圈闭成藏过程提出了动态分析的综合研究方法。通过对典型岩性油藏动态解剖,重点研究岩性圈闭成藏过程中主要形成要素的演化特征,着重恢复地史时期烃源岩地层压力、储集层孔隙度、油气充注、岩性圈闭形成等关键因素在时空变化中的演化规律,同时对各成藏要素进行综合分析,确定岩性油藏形成的动态演化过程。研究结果表明,西峰地区长8岩性油藏为近源高压成藏模式,具有成藏动力和储集层临界物性“二元控藏”的特点。

Abstract: This paper presents a newly developed dynamic analysis method for lithologic?trap reservoir evolution. Taking a typical lithologic reservoir as an example, the evolution of main elements contributing to the formation of typical lithological reservoir is studied in source rock pressure, reservoir porosity, oil?gas charging, lithologic?trap formation, building up the dynamic model of the formation of lithologic reservoir. The results show that the model of Chang?8 lithological reservoir in Xifeng area belongs to near?source and high pressure hydrocarbon accumulation model with features of dual elements controlling the reservoir by migration drive force and critical physical properties of reservoir
