摘要: 根据油气勘探实践揭示出常用成藏期研究结果与客观实际的矛盾,较全面地分析了诸如流体包裹体分析、自生伊利石同位素测年等新技术应用于成藏期确定时,在前提假设、方法原理和适用范围等方面的失误或不足。从构造控矿角度,分析了地震与含油气系统的必然联系,指出断褶构造运动是包含油气在内的地层流体运移的主要动因,指出发生在烃源岩供油气阶段的断褶构造活动期,才是烃源岩得以大规模排烃和油气运聚成藏的时期。

Abstract: Based on oil and gas prospecting practice, this paper presents the contradictions between studied conventional reservoir-formed stages and field situations,and evaluates the application of technologies as fluid inclusion enclaves analysis, autogenous llite isotopic dating to determination of reservoir-ormed stage, then points out some mistakes existed in precondition assumptions, tchnical principles and practical ranges. Also, positive connections between seismic infornation and petroleum systems are analyzed. The result shows that a principal kinetic factor for reservoir fluid migration is fault-fold structural movement in which episode potential hydrocarbon source rock could provide large-scale hydrocarbons drainage, migration, accumulation and forming reservoirs.
