The sedimentography characteristics of Daniudi gas field

Abstract：Daniudi gas field lies in the the norhthern part of Yishan slope of Ordos basin, its main purpose intervals includes: Taiyuan team. CARBONIFEROUS. Late PALEOZOIC, Shanxi team. PERMIAN, late Shihezi. PERMIAN, these intervals went through the sedimentary process of marine facies—the transition of marine and contimental facies—contimental facies. Taiyuan team is considered as the littoral_nertic facies deposit (with some barriers bar facies deposit) , Shanxi team is considered as delta facies deposit, late Shihezi team is considered as fluvial facies deposit through the observation of the core of more than 50 wells and the analyse of the core data. The characteristics of the micro_sedimentography on the basis of the research on the sedimentography is described.
