四川盆地嘉陵江组岩相古地理与聚钾中心预测
摘要
Abstract
Lithofacies-paleogeographic research and woven figure is an important basic geological work. This article renews the lithofacies-paleogeographic in nine reservoir section of Jialingjiang formation in Sichuan basin for the first time, The key salty sub horizons distribute in T1j24 T1j44, T1j5 ,T1j25 formations in vertical. In the areas, theplaster, salinastone basin mainly distributed in midland to northeast of the Sichuan basin. Using single well brine formation water chemical analysis data and the research 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, we predict and delineate the rich halogen center and aggregate potash center, which indicate the direction of exploring rich potassium brine in the lower Trias-sic, Jialingjiang group of sichuan basin.关键词
