摘要
This paper renews the lithofacies-paleogeographic in nine reservoir section of Jialingjiang Formation in Sichuan Basin.The key salty sub horizons distribute in T1j42、T1j44、T1j51、T1j52 formations in vertical.In the areas,the plaster,salinastone basin mainly distributed in midland to northeast of the Sichuan Basin.Using single well brine formation water chemical analysis data and the results of the important salty sub horizons’ lithofacies-paleogeographic,the Jialingjiang Group brine’s distribution was analyzed.According to the standard of rich potassium brine industrial production index,the authors predict and delineate the rich halogen center and aggregate potash center in the lower Triassic,Jialingjiang group of Sichuan Basin.
