Abstract

Abstract:

This paper takes the shale samples from the Wufeng Formation and the first member of Longmaxi Formation in the Sichuan Basin and its periphery as the research subject. Through the comparative analysis of drilling data， core and outcrop analysis， and test data， a study on the sequence stratigraphic division and correlation， lithofacies classification and identification， and sedimentary microfacies-lithofacies distribution of the rocks is carried out. The results show that the fine-grained deposits of study interval can be divided into three third-order sequences （SQ1， SQ2， and SQ3）， which are subdivided into seven systems tracts. High-quality shales are mainly distributed in the transgressive systems tracts （TST） of the three sequences， of which high-quality shales of SQ2-TST are the most widely distributed. The lithofacies are mainly organic siliceous shale， organic-rich limy siliceous shale， and medium-high organic siliceous argillaceous shale. The regional distribution of different types of inorganic minerals is clarified. The contents of carbonate minerals are relatively high near the central Sichuan paleo-high and northern Guizhou Uplift. With the increase of water depth， the contents of clay minerals and quartz minerals gradually increase. The sedimentary-lithofacies of SQ2-TST is mapped by using the contour maps of the content of three terminal principal minerals （quartz， clay， and carbonate） and the content of total organic carbon （TOC）， in combination with the contour maps of parameters such as geochemical parameters （Th/U） and isopachous maps. On the periphery of the central Sichuan paleo-high， central northern Guizhou paleo-high， and northern Sichuan paleo-high， medium-low organic argillaceous shales and medium-low organic limy siliceous argillaceous shales deposited. In the deep-water shelf of southern Sichuan Basin enclosed by the central Sichuan paleo-high and central northern Guizhou paleo-high， organic-rich limy siliceous argillaceous shales are mainly deposited. organic-rich siliceous shales are mainly developed in the Fuling area extending to the northeast of the Sichuan Basin.
