油田储层非均质性分布规律的认识是深水油田产能指标设计的重要依据,因此是深水油田开发的关键影响因素之一。针对南海深水流花D油田珠江组下段储层展开层内、层间和平面非均质性分析,并结合沉积环境和成岩作用深入研究,厘清了油田内部非均质性分布认识。研究认为南海深水流花D油田隔层和夹层的分布是非均质性的重要影响因素,储层内发育隔层6套,夹层9~10套;此外,油田位于古陆架坡折带附近,沉积由三角洲前缘向浅海陆棚碳酸盐台地转变,在海侵的大背景下,水动力条件变换引起的沉积物变化是影响研究区储层非均质性的主控因素。

The heterogeneous distribution of oilfield reservoirs significantly impacts the production capacity in deep-water oilfields. This study focuses on the intra-layer, inter-layer, and planar heterogeneity of the lower section of the Zhujiang Formation in the Liuhua D deep-water oilfield in the South China Sea. Through in-depth research in combination with sedimentary environments and diagenetic processes, the internal heterogeneity distribution of the oilfield is clarified. The study suggests that the distribution of interlayer and interbeddings is an important factor influencing heterogeneity in the oilfield. There are six sets of interlayers and nine to ten sets of interbeddings in the reservoir. In addition, the oilfield is located near the ancient continental shelf break zone, where sedimentation changes from a delta front to a shallow-water carbonate platform. Under the background of marine transgression, sedimentary variations caused by the change in water dynamics are the main controlling factor affecting reservoir heterogeneity in the study area.
