Development and Evolution of Inner-Platform Shoal with Control on the Reservoir in a Sequence Framework of Lower Cambrian Longwangmiao Formation, Moxi-Gaoshiti Area, Central Sichuan Basin
摘要
Abstract
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.关键词
