| 摘 要： | 油气藏的形成是在一定的地质背景下,油气由分散到集中的漫长的地质过程.油气分布受多种因素的影响,生、储、盖、运、圈、保、异常压力等各种地质条件都可以决定油气的最终分布.在分析了纯粱油田沙二段油气成藏基本条件和已发现油气藏特征的基础上,总结了该区油气分布的规律和成藏模式,应用管理经济学中的"木桶原理",提出了"短板"控油的说法.结合工区实际情况认为:①圈闭条件是决定研究区油气分布的"短板";②通过层序地层学研究寻找岩性、地层等隐蔽性圈闭以及通过精细构造研究寻找小型构造圈闭是加长"短板"、勘探沙二段油气资源的关键.

| Abstract: | The formation of oil-gas reservoirs is a long geological process,in which the oil-gas accumulates together from dispersion.The oil-gas distribution is affected by many factors,such as source rock,reservoir bed,cap rock,migration,trap,preservation,abnormal pressure,and so on.The oil-gas distribution law and the oil-gas reservoir forming modes in the studied area are induced based on the analyses of the basic forming conditions of the Es2 reservoir and the characteristics of the founded oil-gas accumulations.The theory of "short board" control oil is put forward based on the "cask principle" in management economics.It is held that trap is the "short board" of controlling the oil-gas distribution in the studied area,and looking for lithologic and formation subtle traps by the study of sequence stratigraphy and looking for small structural traps by fine structural study are the key to lengthening "short board" for the exploration and development of the Es2 reservoir. |
