The Characteristics of Sedimentary Facies of Tanzhuang Formation of Upper Triassic of Luoyi District

Abstract:

Based on the observation and description of single well and outcrops and the analysis of reservoir compositions, petrology, clastic structure and sedimentary structure,this paper determines the sedimentaty facies characteristics of Tanzhuang formation. The types of sedimentary facies in late Triassic epoch are delta front,shallow lake and semi-deep lake. The delta front develops subaqueous distributary channel, mouth bar and distal bar. Lacustrine facies develops shallow lake mud, shallow lake sand bar, turbidite sand and semi-deep lake mud.The reservoir rock formations in this area are lithic sandstone,feldspathic lithic sandstone with high content of feldspar and debris.The sedimentary structures include ripple, scour surface and cross-bedding are identified.
