THE HYDROCHEMICAL CHARACTERISTICS OF NON-MARINE OIL-FIELD WATER IN CHINA AND ITS EVOLUTION PATH

Liu Chongxi ( Comprehensive Brigade of Petroleum Geology, Ministry of Geology)  
Basing on a large number of analytical data, the hydrochemical characteristics of non-marine oil-field water in China and its evolution path are discussed. Along with the generation and development of sedimentary basin, the non-marine oil-field paleowater underwent a series of complicated processes of hydrogeochemical evolution, and eventually transformed into the present status. The hydrochemical composition changed along a main trend with increasing concentrations of anion Cl- and cation Na+. The differences among hydrochemical types depend on the concentrations of secondary ions and the degree of mineralizationi meanwhile, the degree of mineralization and the hydrochemical type show distinct zon-ation from north to south, reflecting the influences of paleoclimatology and paleohydrochemistry. In addition, the formation, occurrence, and circulation of oil-field water, and the evolution of hydrochemistry accorded with the formation, migration and accumulation of oil and gas. All these were strictly controlled by the second-ordered tectonic elements-sedimentary depressions-within the petroliferous basins and thus appeared as a single complex during hydrochemical evolution. This is an important characteristic of non-marine oil-field water.
