众所周知,对于油气资源的预测工作来说,探讨有机质的演化史具有极其重要的意义。近几年来,关于这一问题的定量研究方法在国内外均有所报道。其中较有影响的方法之一是由(1969,1971)提出并经 Waples(1980)充实的时间-温度指数(TTI)法。该方法的优点是考虑了盆地的沉积史和构造史对有机质热演化过程的影 As we all know, for the prediction of oil and gas resources, to explore the evolution of organic matter has an extremely important significance. In recent years, quantitative research methods on this issue have been reported both at home and abroad. One of the more influential methods is the time-temperature index (TTI) method proposed by (1969, 1971) and enriched by Waples (1980). The advantage of this method is that it considers the influence of the sedimentary history and tectonic history of the basin on the thermal evolution of organic matter
