摘要(Abstract)：

根据常规物性分析、测井解释、岩石薄片、岩石碳氧同位素等,研究文昌10区珠海组扇三角洲沉积储层厚度与物性分布;考虑沉积环境、成岩作用等,分析不同层段低渗成因及物性影响因素,确定"甜点"储层控制因素与分布.结果表明:胶结强度差异为珠海组一段和二段"甜点"储层控制因素,扇三角洲前缘水下分流河道断裂活动速率较低、略远离南断裂较高压力的低钙质胶结区为"甜点"储层发育区;压实、溶蚀强度与砂岩粒级为珠海组三段"甜点"储层控制因素,水下分流河道/河口坝粗粒度、较弱压实、强溶解带为"甜点"储层发育区.该研究为勘探有利区带预测提供地质依据.

关键词(KeyWords)：沉积相;成岩作用;“甜点”;低渗储层;珠海组;南断裂带;文昌A凹陷
