| 摘 要： | 本文根据生油岩的矿物组成、有机质的分布形式及泥岩的基本压实特征,建立了生油岩的测井响应方程,并用实际资料分析了生油岩在测井曲线上的特征。据此,我们采用图版法、I_x指数法和多元回归法、利用泥质砂岩的韦-史方程,提出了重迭、双孔隙度法对生油岩进行了评价,同时,提出了用碳/氧比测井计算有机碳的公式,并对双检2井取心井段的生油岩做了试算,结果令人满意。

| Abstract: | In this paper, the'mineral composition and the basic compaction characteristics of the source rock and the distribution forms of the organic matter in the source rock have been discussed. The characteristics of wireline log for the source rock have been studied and the source rock in Nanyang depression has been evaluated by using the crossplot analysis, Ix indicator and the multiple regression analysis methods, The paper has also estimated the source rock by using Overlay and Dual-porosity methods With Waxman-Smith equation. Meanwhile, it has forward the equation which can be used to calculate the total organic carbon of the source rock with carbon-oxygen logging. The data computed in shuangjian-2 well are proved to be suitable. |
