| 摘 要： | 烃源岩评价是油气勘探的关键工作之一。为了更加合理、直观和有效地评价烃源岩,以辽东湾地区为例,通过对烃源岩常规评价参数的分析,提出了考虑有机质丰度、类型和热演化程度的综合指标——成烃贡献值,并利用该指标对辽东湾地区烃源岩进行了评价。从个体评价和整体评价两方面,与常规评价方法的结论进行对比研究。结果表明,辽东湾地区辽中凹陷沙河街组烃源岩对成烃的贡献比东营组大,中洼烃源岩比北洼好。由此可见,用成烃贡献值评价烃源岩,不仅可以达到常规评价的要求,而且比常规方法更加合理和直观。

| Abstract: | The evaluation of hydrocarbon source rocks is one of the keys in the oil and gas exploration.We carried on the research of the evaluation of hydrocarbon source rocks.The value of hydrocarbon of generation(VGH) as an integrated index that characterized the organic abundance,type and maturity,was suggested to evaluate the hydrocarbon source rock in Liaodong Bay,and the results was compared to the individual and overall evaluation of the general methods.The results showed that the contribution of source rocks in Shahejie Group are higher than Dongying Group,and the source rocks in Middle Sag are higher than North Sag,which proved that evaluation of source rock based on the value of generation hydrocarbon may not only meet the general evaluation requirements,but also be more rational and intuitive than the normal methods. |
