Abstract

On the basis of formation development characteristics, this paper studied the high-resolution sequence stratigraphy division of the fourth member of Xujiahe Formation in central fault-fold belt of Yuanba area. Firstly, based on the sedimentary characteristics of modern braided river and braided river delta, we clarified the braided river sedimentary system and braided river delta sedimentary system. Through the drilling and logging data, we defined that the study area developed braided river facies and braided river delta facies. And then, according to the principle of high resolution sequence stratigraphy, we identified two types of braided channel which have sequence stratigraphy significance, including high accommodation vertical superimposed braided channel and low accommodation lateral superposed braided channel, which can be used to judge the transformation position of base level cycle for single well high resolution sequence division. It was considered that the fourth member of Xujiahe Formation can be divided into two fourth-order cycles and three sub-members. Finally, combined with the seismic sequence interpretation of the fourth member of Xujiahe Formation, we established regional sequence stratigraphic framework, which provides foundation for the further study on sedimentary facies distribution in sequence stratigraphic framework.
