摘　　要：根据最新的地层划分对比方案,首次分析了研究区沙湾组储层特征及其影响因素。研究区储层主要为辫状河道、辫状河三角洲平原分流河道及前缘水下分流河道砂体。通过储层的岩石学、物性及孔隙类型分析,认为影响储层的主要因素是不同沉积环境的不同岩性、碳酸盐含量以及成岩作用,其中沉积环境起主导作用,控制着储集砂体的发育与分布,而后两者在局部地区对储集砂体物性影响较大。Based on the newest method of division and correlation of Shawan formation, the article analyzes firstly the characteristics of Shawan formation in the study area, and discusses influential factors. The reservoirs in the study area are mainly braided river channel sand body, braided plain distributary channel sand body and delta front underwater distributary channel sand body. And the controlling factors of reservoir development are rock type of different sedimentary environment, carbonate cements content and diagenesis. Sedimentary environment play an important role, and sedimentation controls development and distribution of reservoir rocks, however, latter two factors have a major influence on the physical property of reservoir rocks in part area.
