摘要/Abstract

摘要： 根据Ⅱ₂型湖相泥岩的加水热模拟实验结果与油气生成一般规律的研究,提出了热模拟结果应用于含油气盆地的生油气量计算的校正方法。认为各种怪源岩样品的热模拟实验结果与实际的油气生成模式均有一定偏差咱不能直接应用于盆地炬源岩的生油气量计算。在校正时选1%作为生油高峰对应的镜质体反射率（R。）,在不同盆地或对于不同类型炬源岩可能有所不同,应根据某一盆地的怪源岩实测演化剖面来选定生油高峰对应的R。,由干生炬机理上氢气与甲炕没有明显的联系,指出总气态产物中的氢气不应作为炬气的一部分计算噜必须根据校正后的R。建立油气产率的数学模型和编制相应的困版。

Abstract: Base on thermal simulation experiment of lacustrine mudstone of Type 112 and petroleum generation pattern, this paper propos-es the correction method for estimation of hydrocarbon generating quantity in oil gas bearing basin from the thermal simulation result. It is suggested that these thermal simulation result can not directly be used to estimate the quantity due to presence of certain errors compared with real hydrocarbon-generating patterms. The sclection of vitrinite reflectance at oil generating peak when correction should be based on measured source rock evolutive section in a basin for different basins or different source rocks have somewhat different vitrinite re-flectance. In addition, no distinct relationship between hydrogen and methane in hydrocarbon-generating mechanism means that estimation of gas quantity should exclude hydrogen in gross gaseous hydrocarbons. Corrected vitrinite rellectance has to be adopted to develop mathematic models for oil-gas production rate and related charts.

Key words: hydrocarbon generation, thermal simulation, resource evaluation, mathematic model
