摘　　要：以阜东斜坡韭菜园子组为研究对象,利用岩性观察、岩石薄片镜下鉴定等岩石实验分析手段,对韭菜园子组储层特征及主控因素进行了探讨,结果表明:岩石岩屑含量高,主要矿物成分为石英、斜长石,局部地区沸石、方解石含量较高;韭一段及韭二段主要发育冲积扇,以辫状水道沉积为主,物源来自南部的博格达山及北部克拉美丽山,沉积具有南北混源特征;主控因素主要包括岩相作用和成岩作用,其中中砂岩相和中细砂岩相储层物性最好,方解石压实作用会破坏储层物性,沸石的溶蚀作用及绿泥石胶结会一定程度上改善储集层性能。从微观至宏观深入分析了储层物性,建立了工区的沉积规律,明确了砂体展布特征,通过逐条分析储层含油性的控制因素,为开发方案的部署提供了依据,为下一步勘探方向提供了理论支持。Taking the Jiucaiyuanzi Formation on the Fudong Slope as the research object,the characteristics and main controlling factors of the Jiucaiyuanzi Formation were discussed by means of lithological observation,rock thin section microscopic identification and other rock experimental analysis methods.The results showed that:the content of rock debris main mineral components were quartz and plagioclase,and the content of zeolite and calcite was relatively high in local areas;alluvial fans were mainly developed in the 1st and 2nd members of Jiu,which were mainly deposited by braided channels,and the provenance came from the Bogda Mountain in the south and Kelamei Mountain in the north,the sediments had the characteristics of mixed source from north and south;the main controlling factors mainly included lithofacies and diagenesis,among which medium sandstone facies and medium fine sandstone facies had the best physical properties of the reservoir,and calcite compaction would destroy the physical properties of the reservoir,the dissolution of zeolite and the cementation of chlorite will improved the reservoir performance to a certain extent.The physical properties of the reservoir were deeply analyzed from the microscopic to the macroscopic level,the sedimentary law of the work area was established,the distribution characteristics of the sand body were clarified,and the controlling factors of the oil-bearing property of the reservoir were analyzed one by one,it provided the basis for the deployment of the development plan and provided the theoretical support for the next exploration direction.
