| 摘 要： | 采用半封闭外加温加压式热压模拟装置对碳酸盐岩的生烃情况进行了热模拟实验。利用自然样品和人造样品相结合,研究了碳酸盐岩生气量随成熟度和温度变化的趋势,探讨了碳酸盐岩的生气规律:碳酸盐岩气态烃产率随温度升高而增大,并且在某一温度点(460℃)之后,气态烃产率的增大非常明显;温度是碳酸盐岩生烃的重要影响因素;随着温度增高,碳酸盐岩的生烃潜力不断降低,其间有一个生烃潜力的巨变阶段;碳酸盐岩生烃过程中,总有机碳TOC变化不明显,这可能与样品本身的TOC太低有关;碳酸盐岩的气态烃产率与有机质丰度的关系并不明显。

| Abstract: | The thermal simulation experiment, adopted to research hydrocarbon generation in carbonate rocks, used analyze gaseous products in different temperature phase with PY-GC. The gas generating rule was concluded that the key factors controlling the generation of hydrocarbon were temperature and total organic content. The yield of gaseous hydrocarbon ascending with the temperature increasing, a peak appeared at some temperature degree (460℃); the hydrocarbon-generating potential of carbonate rocks decreased gradually with temperature rising, and fell very fast at the certain evolution stage. In the course of hydrocarbon generation, the total organic matter abundance did not almost change. It was not apparent that organic matter content influenced productive rates of hydrocarbon. |
