The depositional facies of Lower Triassic Jialingjiang Formation in Chishui area of Guizhou Province belongs to continental-marine carbonate platform deposition. Based on field outcrop in combination with drill core, this paper divided the sedimentary facies into several types and pointed out that beach subfacies and dolomite-flat microfacies are depositional facies zones in favor of the development of T₁j^2-1-T₁j¹ and T₁j^5-1 reservoirs in this area and, using the “single factor analysis and multifactor integration graphing method”, obtained compositional thickness percentage distribution trend of different petrographic categories in the T₁j^2-1  layer. On such a basis, the depositional facies of T₁j^2-1-T₁j¹ and T₁j^5-1 favorable segments were also analyzed.
