Abstract: Integrative quantitative and qualitative research of preservation conditions of oil and gas pools are presented.The qualitative study includes cap rocks,faults,uplift and denudation,magmatic activity,time and space spans of source rocks,reservoirs and cap rocks,physical property of reservoirs and cap rocks,quality of source rocks,etc..The quantitative study consists of the modelling of dissipating quantity and accumulating quantity of oil and gas.Based on the study and contrast of the preservation conditions of four oil and gas pools,seven qualitative geological criterions and two quantitative evaluation parameters are posed,they are scientific basement for studying preservation conditions of oil and gas pools.

Key words: oil and gas pool, integratian, research, preservation condition, simulation, secondary migration

摘要： 从盖层、断层、抬升剥蚀、岩浆活动、生储盖组合的时空跨距和储、盖层岩石物性和源岩质量等方面进行了油气藏保存条件定性的研究,并从油气的散失量和聚集量的模拟,对保存条件进行了定量的研究.通过4个油气藏(田)保存条件的研究和对比,提出了保存条件定性评价的七个地质标准和两个定量评价参数,为油气藏保存条件的综合研究提供了较科学的依据.
