摘要 本文对不同类型源岩进行了热模拟研究,结果表明:不同类型源岩在相同模拟温度的热作用下,形成的镜质体反射率有很大的差别;不同类型源岩的有机质在热模拟演化过程中,液态烃高峰产率期出现的模拟温度阶段也存在明显的差异.因此,用镜质体反射率作为造岩作用阶段和油气形成阶段划分的指标时,应该考虑源岩性质和有机质类型等的影响。 This paper studies different kinds of source rocks including coals, carbonaceous mudstones, oil-shale, argillites and limestones collected throughout China and reports the important results as follows: There are great differences of vitrinite reflectance values (R0% ) formed under the thermal process with same simulating temperature among different kinds of source rocks. And the simulating temperature stages of high-peak production of liquid hydrocarbons produced during the thermally simulating process of organic materials from different kinds of source rocks are also apparently different. So, it is important to pay attentions to the influence of source rock properties and organic material types while vitrinite reflectance taken as an index to divide lithogenetic stages and oil-gas forming stages.
