| 摘 要： | 通过成岩分析,将川西前陆盆地须家河组储层分为压实压溶成岩相、碳酸岩胶结交代成岩相、粘土矿物(伊利石)胶结交代成岩相、绿泥石环边胶结成岩相、不稳定组分溶蚀成岩相和破碎裂缝成岩相、石英次生加大成岩相、有机质充填成岩相等8种单因素成岩相,并从构造、沉积和成岩作用三类储层要素入手分析其成因及展布,在此基础上划分出须家河组综合成岩相。冲断带发育的压实破碎硅质胶结成岩相、近前渊三角洲相砂体中发育强压实溶蚀绿泥石衬边胶结成岩相和前隆带三角洲相中发育的中压实溶蚀绿泥石衬边胶结相均可形成较好的储层。

| Abstract: | Based on diagenetic analysis,the reservoir of the upper Triassic Xujiahe Formation in the Western Sichuan foreland Basin can be divided into eight types of diagenetic facies such us compaction-pressolution facies,carbonate cementation facies,lining chlorite facies,dissolution facies and fracture facies based on single factor.Then the distribution of diagenetic facies of the single factor and their origins are studied based on the analyses of the reservoir's structure,sedimentation and diagenetic background.Then the comprehensive diagenetic facies of the upper Triassic Xujiahe Formation are suggested also.It is concluded that that the compaction-fracture-siliceous cementation facies of the thrust belts and the compaction-dissolution-chlorite coating facies of foredeep zones are more favorable for hosting oil. |
