The paper summarizes our recent work in fluid-rock interaction in sedimentary basins in China. We show some results of experiments to dissolve microcline, address origin and evolution of oilfield water in terms of stable isotopic composition and chemical data, and present cases to show thermochemical sulfate reduction ( TSR) and bacterial sulfate reduction (BSR) in the Sichuan basin, Ordos basin and Tarim basin. The study implies that water-rock interaction and organic-inorganic reactions in oil and natural gas reservoirs are very common processes which are not fully realized presently.
Key words： organic-inorganic reaction; formation water; sulfur isotope; boron isotope
