SIMULATION EXPERIMENT RESEARCH OF CATALYSIS OF FERROUS ION IN HYDROCARBON GENERATION FROM ORGANIC MATTER IN CARBONATE ROCKS
亚铁离子对碳酸盐岩有机质成烃演化的催化作用模拟实验研究

The high maturated carbonate hydrocarbon source rocks from Sichuan basin were studied by use of dry process, watering method, adding iron and adding sour simulation experiment. The experiment research result indicated that the temperature is a most important factor to control the decomposition of organic matter. From the yield and composition changing characteristic of gas, water is one of the most important factors to hydrocarbon generation in source rock at the range of experimental temperature. Some transition metal elements, such as Fe~\{2+\},in the water are important catalysts for the evolution of organic matter.
