| 摘 要： | 沉积盆地的波动过程分析是建立在成因研究基础之上的全新的含油气盆地分析的理论方法,它能够定量地重塑沉积和间断的空间分布,恢复无沉积记录时间段的沉积-剥蚀过程,计算不整合的剥蚀量,分析沉积、沉降中心迁移规律,建立波动周期与构造沉积演化阶段的内在联系,揭示沉积波动特征与油气成藏要素的相关性,进而从全新的角度探讨盆地油气形成和分布规律。结合楚雄盆地井和剖面波动过程分析实例,归纳总结出了生、储、盖层的纵向分布规律与沉积-剥蚀波动过程曲线的耦合关系,揭示了沉积盆地波动特征与生、储、盖层以及油气运移通道(不整合面)之间的内在联系,建立了四种相应的耦合关系模式,这对于预测含油气盆地有利生油层、储集层、盖层时空分布规律和有效地指导油气勘探具有重要的意义。

| Abstract: | The wave process analysis of sedimentary basin is bran-new theory and method on oil and gas basin analysis. Based on the wave principle and method, the deposition and erosion processes of the deeper part or its vicinity, where strata data are unknown, can be predicted, and the erosion thickness can be calculated and the evolutionary history of the basin can be restored in detail. The transferred law of deposition and subsidence center can be found, and the relativity between wave characteristic and petroleum geologic factors can be recognized,so all of these results make it possible that we discuss the low of petroleum forming and distributing from bran-new point of view. In this paper, a case study on Chuxiong basin is given. These coupling relationships between wave characteristic curve and source,reservoir and cap rocks are established by wave processes analysis for wells and sections of Chuxiong basin, and four kinds of coupling patterns are given, in which the source layer occur at the transition position of the wave curve in the right of datum line, the reservoir lie in the wave crest position of the wave curve in the right of datum line, the cover locate in the trough position of the wave curve the in right of datum line, and the migration channel(unconformity) appear on the trough position of the wave curve in the left of datum line. These research achievements are of important significance for predicting space-time distribution law of source,reservoir and cap rocks, and for effectively instructing oil and gas exploration. |
