层主要分布在磨溪井区的台内滩发育区、西北部的剥蚀区边部，东部、南部主要为ⅡI、Ⅲ类储层。关键调：龙王庙组；层序；储层；碳酸盐岩；台内滩

Abstract: Lower Cambrian Longwangmiao Formation in Moxi-Gaoshiti area of Central Sichuan Basin is the carbon-ate stratum. According to the core, well logging data and so on, on the bases of the sequence division and sedimen-tary analysis, Longwangmiao Formation reservoirs were predicted. The achievements show that there are two se-quences in the formation, the reservoirs are mainly developed in the highstand system tract, Sequence-2 is charac-terized by the relative better reservoir type and connectivity and moreover larger distribution area; Longwangmiao Formation is the restricted platform, which can be divided into four subfacieses : platform flat, intra-platform shoal, interbank flat and lagoon, the reservoirs are generally developed in the second subfacies; according to the physical properties of the reservoirs, Type- I reservoir is principally distributed in the developed block of the intra-platfom shoal of Moxi Well Block and the denuded margin in the northwest, Type- II and II reservoirs are mainly distributed in the east and south.
Key words: Longwangmiao Formation; stratigraphic sequence; reservoir; carbonate; intra-platform shoal
