珠江口盆地东沙隆起珠江组沉积环境及演化
|
摘要
珠江口盆地东沙隆起是重要的油气勘探领域。通过对珠江口盆地东沙隆起的岩心观察描述和岩石薄片鉴定,确认其主要的岩石类型及生物组合,结合地震、测井、录井资料,将珠江口盆地东沙隆起珠江组划分为开阔台地相、台地边缘相、台地前缘斜坡相、海滩相、陆棚相5个沉积相,并进一步划分出9个亚相及若干微相。在此基础上,讨论珠江组沉积相空间展布特征,对其沉积环境演化进行分析,认为珠江组碳酸盐岩主要经历了初、早、中、晚4个阶段的演化过程。为研究区的储层发育、分布特征研究及有利储集相带预测提供了有力的依据。
The Dongsha uplife in Pearl-river Mouth Basin was one of the important oil exploration areas.By core description and observation of the thin rock section,the main rock types and biological composition were confirmed.In combination with seismic,well logging and core data,Zhujiang Formation was divided into open platform,platform margin,platform margin slopes,beaches,continental shelf and other sedimentary facies,and it was further divided into 9 subfacies and microfacies.On the basis stated above,the spatial distribution of sedimentary facies is discussed,and the features of its evolution are analyzed,it is considered that carbonate rocks in Zhujiang Formation experience four stages of evolution,such as the initial,early,middle and late stages.It provides a strong basis for predicting the favorable reservoirs.
