川中磨溪—高石梯地区龙王庙组可划分为两个三级层序.通过大量岩心、薄片以及测井资料综合分析,磨溪—高石梯地区龙王庙期整体属于局限台地沉积,可划分为台内滩、滩间洼地以及潟湖亚相.以台内滩颗粒含量、沉积构造以及单层滩体沉积厚度为基础,结合测井响应特征分析,将台内滩划分为滩核、滩翼以及白云岩坪等微相,并建立了台内滩的3种典型沉积序列:滩翼—滩核—白云岩坪、潟湖—滩间洼地—台内滩,以及滩间洼地—台内滩.层序格架内台内滩的纵横向发育特征表明:SQ2时期较SQ1时期更为发育,滩体单层厚度和总厚度均较大,层序界面附近的滩核—白云岩坪沉积序列上部为最有利的储层发育相带.

Lower Cambrian Longwangmiao Fm. can be divided into two third-order sequences in Moxi-Gaoshiti area, central Sichuan Basin. According to the cores, thin-sections and logging data, it is indicated that the restricted platform during Longwangmiao period in Moxi-Gaoshiti area can be divided into inner-platform shoal, intershoal and lagoon. Based on the grain content, sedimentary structure, thickness of a single shoal as well as interpretation of well-logging, the inner-platform shoal is divided into shoal body, shoal flank and dolomitic flat. Three typical sedimental sequences are setup, all with a shallowing-upward succession. On the characteristics of spatial development in sequence framework, the inner-platform shoal developed more widely in SQ2 than in SQ1, with larger thickness of a single shoal and the total thickness of shoals. The most favorable reservoir developed at the upper part of succession of shoal body-dolomitic flat near the sequence boundary.
