Study on Sedimentary Characteristics and Models of River Group Sequence

Abstract:

Zhunzhong area Qingshui River group has top and bottom boundaries,which are not clear,and research on the evolution of the lack in sequence stratigraphic framework of deposition and on the reservoir sand body types do not have a clear understanding problem.In seismic interpretation, core description and based on the analysis of the related test,combining with the mud logging and well logging data,for the redefinition of Qingshui River group on the top and bottom boundaries,it identifies 6 time significance of sequence boundary,taking Qingshui River group can be divided into 2 sequences, 5 system tracts;clear and definite the study area mainly developed delta lacustrine depositional system,which can be further divided into the delta front subfacies, beach bar facies and semi deep lake subfacies. It takes an analysis on the sedimentary characteristics and distribution rules of different types, and it controls effect of topography and hydrodynamic conditions on deposition system, and then puts forward the corresponding sedimentary patterns.
