摘要
对采自中国四川盆地的高演化碳酸盐烃源岩进行了干法(原样)、加水、加铁、加酸等多介质条件下的模拟实验研究。结果表明,温度是控制有机质分解的最主要因素。从气态的产量及组分变化特征上来看,在研究温度范围内,水是烃源岩中有机质成烃演化的重要因素之一,水不仅是烃源岩中有机质成烃演化的重要氢源,而且水的酸碱性也是烃源岩中有机质成烃演化的重要因素之一;水溶液中溶解的过渡金属元素,如Fe2+,是有机质成烃演化的重要催化剂,Fe2+的存在可明显提高有机质的热解成烃过程,同时使有机质大量转化为烃类气体,而不是二氧化碳。
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.
