Study on Sedimentary Facies of Carboniferous Kalashayi Formation in the South of Tahe Oilfield

Abstract:

Tahe Oilfield is an significant petroleum exploitation and development area in Tarim Basin for SINOPIC. Carboniferous Kalashayi Formation has become an important oil-bearing series for increasing and maintaining production, and for finding backup resource in this Oilfield. Based on the theories and methods of sedimentology, by using the sesmic, log and core data, the sedimentary facies of Carboniferous Kalashayi Formation in the south of Tahe Oilfield are analyzed deeply. Through the study of characteristics of the rock type and texture,sedimentary structure, sedimentary sequence, stratic structure, paleontology, geochemistry and geophysics of Kalashayi Formation, the Sand-shale Section is attributed to tidal flat deposits which has a nature of estuary. The study area are mainly dominated by intertidal zone, including mud flat, sand-mud flat, sand flat, tidal channel and mouth bar microfacies. The Up-mudstone Section developed lagoonal facies. This study provides favorable support for the further petroleum exploration in study area.
