| 摘 要： | 埋藏史研究是含油气系统研究的核心内容 ,是研究油气的生、运、聚及成藏过程的关键。在区域背景分析的基础上 ,定量计算了孙虎地区各地层单元的剥蚀厚度 ;通过压实、剥蚀恢复动态地分析了源岩层的埋藏史 ;结合源岩生烃门限分析 ,分析了单井和平面上源岩的生、排烃期。认为孙虎地区存在 3种类型的埋藏史 ;由于二次沉降的幅度小 ,未能超过第一次沉降的幅度 ,所以本区不存在二次生烃问题

| Abstract: | Burial history analysis is an important part of petroleum system research,and is the key of research of hydrocarbon generation,migration and accumulation.On the basis of the regional geologic background analysis,the authors calculate the erosion strata thickness quantitatively,and analyze the burial history of source rock.Through the analysis of the timing of hydrocarbon generation and expulsion,the authors consider that there is a process of hydrocarbon generation and expulsion in the geologic history,but there is no such a process caused by the second subsiding. |
