摘要
运用CDS820GS地球化学分析系统,分析了辽西凹陷某区块1号井烃源岩有机质的热解气相色谱特征、模拟烃源岩热解化学反应的动力学,并结合其它地化分析资料对烃源岩的有机质类型及热演化程度进行了研究。沙三段和东下段为两套主力烃源岩。沙三段以偏腐泥的过渡类型有机质(Ⅱ_1)为主,其热演化过程为中等;东下段以偏腐殖的过渡类型有机质(Ⅱ_2)为主,其热解演化为低成熟。文中还提出了利用热解气相色谱方法划分有机质类型的几项参数指标,分析和讨论了矿物质在热解中的影响。
The type and thermal maturation of organic matter of source-ro-cks of No.1 well in a depression of Liaodong Bay are studied by the use of pyroly-sis gas chromatography and analysis metheds.The formations of Es3 aod Ed3 are proved to be the two main source-rocks The.organic matter in ES3 belongs to type II1 with middle degree of thermal maturation while the organic matter in Ed3 belongs to II2 with lower degree of thermal maturation.
