油气成藏是生、储、盖、运、聚、保诸成藏条件有效作用的结果。成藏条件有个有效性的问题,油气在成藏过程中,无论哪个成藏条件是无效的,油气都很难成藏。要沿着漫长的地质历史轨迹,深入研究成藏条件的有效性,不但要研究现存状态下的生、储、盖层的生烃、储集、封盖能力及断层、不整合、圈闭的发育状态,还应追索其演化历史,研究其时空分布与组合关系,以动态的、发展的观念整体地研究成藏条件的有效性,以寻找现今存在的油气藏。
Hydrocarbon accumulation is the result of the effective function of reservoir formation, reservoir, cap, transport, poly and Baozong formation conditions. Accumulation conditions have a problem of validity. During the process of hydrocarbon accumulation, no matter what accumulation conditions are invalid, it is very difficult for hydrocarbons to accumulate. It is necessary to study the validity of reservoir-forming conditions along the long geological and historical track. It is necessary to study not only the existing hydrocarbon generation, accumulation and capping ability of the reservoirs and cap rocks, faults, unconformities and traps Development state, we should also reclaim its evolution history, study its spatial and temporal distribution and combination relations, and study the validity of reservoir forming conditions in a holistic way with dynamic and developmental concepts to search for existing oil and gas reservoirs.
