层序地层学及其在油气勘探中的运用

起源于被动大陆边缘的层序地层学理论自 1987年问世以来 ,在地学界掀起了一场革命 ,并逐渐扩展到各种类型的盆地和环境。随着层序地层学在我国各大油田的运用 ,获得了许多成功的实例 ,已形成较为完整的研究方法和思路。层序地层学为勘探家提供了一个可预测形成油气藏的地质要素分布规律的层序格架 ,在油气勘探中具有明显的优势。针对我国目前的油气勘探开发形势 ,需要认真研究陆相层序的形成机制 ,寻找非构造油气藏 ;开展含油气大区的层序地层学研究 ,努力寻找新的勘探领域 ;重视高分辨率层序地层学的研究 ,以提高储层的预测水平和精度。

SEQUENCE STRATIGRAPHY AND ITS APPLICATION TO PETROLEUM EXPLORATION

Sequence stratigraphy was originated from the research on passive margin in 1987,it has brought a revolution in geology and the application of this theory is extended to all kinds of basins and settings gradually.With its application to the large oil fields in China, a lot of successful examples have been procured, and an integrity reach way has been formed. Sequence Stratigraphy provides a framework which can be used to predict the distribution of geology elements for explorers, and is of great advantage in petroleum exploration.Aiming at the situation of the petroleum exploration in China,it's necessary to study the genetic mechanism of non\|marine sequence stratigraphy,and to look for the subtle trap.And it's the time to study sequence stratigraphy at a large petroleum province, and to discover the new exploration region.It is important to pay attention to the study of high\|resolution sequence stratigraphy, and to improve the level and precision of reservoir predict.
