Examples
- The regularity of accumulation distribution is ascertained and directs the exploration orientation . the main results obtained in this paper are : 1 . the analyses of hydrocarbon - bearing rock , reservoir , caprock and oil & gas reservoir indicate the source of oil & gas , the space for reservoir , requirement for preservation , reservoir type and its basic characters . 2 . it is realized by the analyses of sealing up capability of caprock and faults , and fault ' slatter stability from microcosmic and macroscopic that the wide - spread regional caprock of nm t prevented oil & gas of neogene from diffusing fault movement in neogene less violated and fault displacement decreased , which are advantageous for the preservation of oil & gas reservoir . and latter structure movement usually formed the accunulation of oil & gas in neogene . 3 . the research of history of hydrocarbon generation and expulsion of main hydrocarbon - bearing rock in qikou depression reveals the threshold depth and the fime of hydrocarbon generation and expulsion
项目研究取得了如下认识： 1 、对烃源岩、储集层、盖层及油气藏展开分析，明确了歧口凹陷上第三系油气藏的油气来源、储集场所、保存条件和油气藏类型及其基本特征； 2 、从微观和宏观上对盖层的封盖能力以及断层封堵和后期稳定性进行分析，认识到明下段区域盖层的广泛分布阻止了上第三系油气藏的油气逸散，同时上第三系断层活动减弱，断距较小，对油气藏的保存较为有利。
