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。
The reservoirs were qualitatively studied from the aspects of cap rock, fault, uplifting and denudation, magmatism, spatiotemporal span and reservoir of reservoir-cap assemblage, petrophysical property of caprock and source rock mass. Accumulation of the simulation, the storage conditions were quantitative research. Based on the research and comparison of the preservation conditions of four reservoirs (fields), seven geological criteria and two quantitative evaluation parameters for qualitative evaluation of preservation conditions are proposed, which provide a scientific basis for the comprehensive study of reservoir preservation conditions.
