据文献报道,造成原油和生油岩组成差异的主要原因有母质的类型、热成熟作用和原油的初次运移作用。研究是何种因素(或以何种因素为主)导致出现组分差异,对油气成因理论和盆地油源对比及资源评价等都具有重要的意义。地质情况的复杂性造成了上述参量组合的多样化,给直接从野外地质剖面进行研究带来了难以克服的困难。为了有意识地简化一些可变参量,本研究采用以同一种生油岩在外加温加压的条件下进行系统的生油和排烃模拟实验来研究这一问题。
According to the literature, the main causes of the composition differences between crude oil and raw oil rock are the type of parent material, thermal maturation and primary migration of crude oil. It is of great significance to study the factors (or factors) that lead to the differences of components, and to the theory of oil and gas genesis, the source of oil source in the basin and the resource evaluation. The complexity of geological conditions has resulted in the diversification of the above mentioned parameter combinations, which has brought about insurmountable difficulties to conduct research directly from the field geological profiles. In order to consciously simplify some variable parameters, this study uses the same source rock under the conditions of external heating and pressure under the conditions of the system of oil and hydrocarbon generation simulation experiments to study this issue.
