摘要
从层序地层学研究入手，将珠江口盆地（东部）21－16.5Ma地层（大致相当于珠江组）划分为2个三级层序、5个体系域和16个准层序组。探讨了砂岩储层的物性、非均质性及其分布规律。通过岩心描述、遗迹古生态、测井相及地震相分析，结合本区沉积相演化特点，对按体系域或准层序组划分的7个层开展了沉积相对空演化规律的研究，分别建立了相应的沉积相模式。剖析了不同沉积微相对砂岩储层物性及非均质性的控制作用。研究表明，沉积环境对砂岩油田产能及开发效果也具有明显的影响。因此，沉积环境研究为制订合理的开发方案建立了良好的地质基础。
Based on sequence stratigraphic study, Zhujiang Formation can be divided into two third-order sequences ,five system tracts and sixteen parasequence sets. Discussion has been carried out on sandstone reservoir, heterogeneity and their distribution pattern. Seven sedimentary facies models had been constructed for the interval of age from 21Ma to 16. 5Ma after integrating core description,ichnocoenosis palaeoecol-ogy,well log interpretation,and seismic facies analysis. It is indicated that sedimentary facies has greatly influenced reservoir properties,reservoir heterogeneity ,distribution of intercalation and effects of produc-tivity and performance. Therefore, the study of sedimentary facies is the geological fundation for making development program.
