| 摘 要： | 在地质低温条件下，未熟生油岩矿物催化脂肪酸脱羧生烃反应生成的ＣＯ２含量很低，因此，通过金属镍催化剂将ＣＯ２转化为ＣＨ４后再用氢离子火焰检测器检测其含量，以提高检测的灵敏度。运用该方法评价了我国七个油田未熟生油岩矿物催化脂肪酸脱羧生烃活性实验结果表明，脂肪酸在未熟生油岩矿物低温催估作用下，其脱羧率与未熟生油岩矿物中的碳酸盐及过渡金属Ｆｅ元素的含量有关。

| Abstract: | It is very low that the carbon dioxide content formed from fatty acid mineral catalytic de-carboxylation at low temperature. In order to increase sensitivity of detecting method, carbondioxide should be converted to methane, then its content is detected by FID. By means of thismethod, the activities of seven immature oil source rocks in China were evaluated. The resultsshow that the activities of fatty acid catalytic decarhoxylation in the immature oil source rocks atlow temperature are relating to the carbonates and transition-metal Fe contained. |
