摘要
Abstract
The Leikoupo Formation of Middle Triassic in Sichuan Basin is one of the series of strata where natural gas and bittern are first explored. So far, three gas reservoirs have been proved and a large number of gas bearing structure have been discovered, but with the continuously deep research of the exploration, there arise certain divergences in recogination to the bottom and top beds of Leikoupo Formation as well as the division of internal strata, which to some extent hindered the exploration and developing deployment of this layer series. This study redefines and clarifies the characteristics of bottom and top boundary by Leikoupo Formation through reexamining the drilling of Leikoupo well and field geological investigation and quantities of assay data. At the same time, division plan and layering comparison work of Leikoupo Formation are done according to the lithologic association, electrical characteristics, cycle characteristics, thus laying a foundation to the further exploration and development of the overall resources in Leikoupo Formation.关键词
