1.前言 在石油勘探技术中地球化学研究的目的之一是予测和查明成油地质带,已经有一些人发表了评价的标准。例如,Philippi(1956)的抽提出的烃量,Ronov(1958)的有机炭含量,Bray和Evans(1961)的CPI,柳下(1962)的转化度等指标。然后近年发表的有法国石油研究所Tissot等的小组基于石油生成机理和它的动力学的思路,研究了在沉积盆地单元中求得成油地质带中石油生成速度的方法。后者的研究的目的在于知悉在成油地质带的所有各个地点上作为时间(埋藏史)的函数的石油形成量。而且,这种研究,结合石油运
1. Introduction One of the purposes of geochemical research in petroleum exploration technology is to predict and identify oil-bearing geological zones. Some people have published standards for evaluation. For example, the extracted hydrocarbons from Philippi (1956), the organic carbon content from Ronov (1958), the CPI from Bray and Evans (1961) and the degree of conversion from Willow (1962) will be used. Then in recent years, Tissot et al., A group published by the French Petroleum Institute, have studied the method for determining the rate of petroleum production in oil-bearing geologic zones in sedimentary basin units based on the idea of petroleum generation and its kinetics. The latter study was aimed at knowing the amount of oil formed as a function of time (burial history) at all of the various locations of the oil-producing geological zone. And, this kind of research, combined with oil transportation
