有机-无机相互作用在矿产资源形成中存在普遍、意义重要,有机油气煤和无机铀同盆共存、富集成藏(矿)的深层原因即为有机-无机相互作用.本文在Ⅲ型低熟烃源岩中加入碳酸铀酰溶液的条件下进行生烃热模拟实验,以探讨油气生成过程中无机铀所产生的影响.生烃实验结果揭示,铀的参与,可使烃源岩中烃气产出率有所提高,总气量增加,产出的总烃量(重量或体积)增加;并可降低烃源岩生烃门限温度,在相对较低温阶段生成液态烃.铀可使产物中饱和烃增多,促使低分子量烃类产生,从而使CH4的产出量提高,生成的烃类的干气化程度增加.铀可能是未熟-低熟油气生成可能的无机促进因素之一.
Organic-inorganic interaction exists in the formation of mineral resources is universal, important, organic oil and gas and inorganic uranium co-exist with the basin, enrichment of accumulation (mineral) is the organic-inorganic interactions deep reason.In this paper, The hydrocarbon generation heat simulation experiment was carried out under the condition of adding uranyl carbonate solution in the source rock to explore the effect of inorganic uranium in the hydrocarbon generation process.The results of hydrocarbon generation reveal that the participation of uranium can make hydrocarbon gas production The rate of increase is increased, the total amount of gas increases, and the total amount of hydrocarbon (weight or volume) output increases; and the hydrocarbon generation threshold temperature of the source rock can be reduced, and the liquid hydrocarbons can be generated at a relatively low temperature stage. Uranium can increase the amount of saturated hydrocarbons in the product , Resulting in the generation of low molecular weight hydrocarbons, thereby increasing the output of CH4 and increasing the degree of dry gasification of generated hydrocarbons.Uranium may be one of the possible inorganic promoters of immature-low mature oil and gas generation.
