摘　　要：总结了作者近年来在中国沉积盆地流体 岩石相互作用方面研究所取得的进展 .给出了长石在有机酸、原油下的溶解作用以及铝硅络合作用的结果 ,基于稳定同位素和水化学数据讨论了油田水的成因和演化 ,并分析了四川盆地、鄂尔多斯盆地和塔里木盆地中微生物和热化学的硫酸盐还原作用 .这些结果隐示出 ,在含油气储层中水 岩相互作用和有机 无机反应是很普遍的 。The paper summarizes our recent work in fluid-rock interaction in sedimentary b a sins in China. We show some results of experiments to dissolve microcline, ad dress origin and evolution of oilfield water in terms of stable isotopic compo sition and chemical data, and present cases to show thermochemical sulfate re duction (TSR) and bacterial sulfate reduction (BSR) in the Sichuan basin, Ordos basin and Tarim basin. The study implies that water-rock interaction and organi c-inorganic reactions in oil and natural gas reservoirs are very common process es which are not fully realized presently.
