油区构造沉积成岩相带研究

A STUDY ON THE STRUCTURAL SEDIMENTARY DIAGENETIC ZONE IN AN OILFIELD

构造演化、沉积作用、成岩作用对油气储层的发育与分布均具有重要的控制作用。其中,构造演化控制了沉积作用及各种沉积体的发育;构造作用、沉积作用控制了成岩事件的发生及成岩相的空间展布格局。在制定油气开发方案前,必须建立一个完整的构造演化、沉积作用、成岩作用的综合模式,进而预测有利构造沉积成岩相带。本文以阿南油田等地区为例阐述了这一观点。

The structural evolution,sedimentation and diagenesis all control impor- tantly the formation of oil and gas reservoir.Structural evolution controls the sedimentation and formation of various kinds of sedimentary body,and struc- tural evolution and sedimentation control the occurrence of diagenetic events and the distribution of diagenetic facies in space.So,before a development scheme of oil and gas is formulated,a synthetic model on structural evolu- tion,sedimentation,and diagenesis should be set up to predict the favourable zones.In this paper,the authors have cited examples,such as Anan oilfield and so on to expound this idea.
