| 摘 要： | 为了有效地在准噶尔盆地红山嘴地区克拉玛依组上段(克上段)寻找有效储集体,利用岩心、铸体薄片、扫描电镜及压汞等资料的综合分析,对研究区的储层特征和储层发育的控制因素进行了研究。结果表明该区克上段储层岩屑含量高,结构成熟度和成分成熟度偏低;分析了控制储层发育的因素,沉积因素(基质含量、岩性及砂砾岩成因类型)是内因,砂砾岩储层中,基质含量与物性成反比;牵引流物性好于洪流型,碎屑流型最差;成岩作用(压实、胶结及溶蚀作用)为外因,压实作用造成砂砾岩孔隙结构变差,胶结作用在富基质和含基质型具有破坏作用,而对于贫基质型起保护作用;通过对砂砾岩储层特征与控制因素综合分析,将研究区的储层分为4类,并绘制了有利储层分布图,扇三角洲前缘内带物性最好,外带次之,平原物性较差。

| Abstract: | To search for effective reservoirs, data of the core, reservoir physical properties, thin-section, SEM and mercury test results from the Upper Triassic Karamay reservoirs of Hongshanzui area were compiled and analyzed, and the reservoir features and controlling factors were discussed. The results show that the reservoirs are mainly lithic arkose and feldspathic litharenite, and that the component maturity is low. The controlling factor analysis suggests that the sedimentary elements (matrix content, lithic and formation of gravel sandstone) are the internal reason. The matrix content is inversely related to physical properties, tractive current is better than flooding current, and the debris current is the worst. Diagenesis (compaction, cement, dissolution) is the external reason. Compaction results in poor pore structure of gravel sandstone. Cementation is destructive in both rich-matrix and containing-matrix conditions, but protective in poor-matrix ones. The four kinds of reservoirs were divided based on the characteristics and controlling factors, and the favorable reservoir distributions were plotted. The reservoir property is likely better in the inner zone of the fan delta than the external zone, whereas the plain is the worst. |
