七十年代以来,用孢粉颜色指标确定有机质成熟度是国外石油公司在研究生油岩时广泛开展的项目。近两年来,国内的一些石油普查勘探部门陆续引进了这一方法。当前,我国正在寻找深部油气资源,并开展大陆架找油研究,这就愈加需要尽快地采用新技术、新方法。 为了探索沉积物中油气生成潜力,采用了各种指标来研究生油岩的油气成熟度,孢粉颜色是讨论有机质成熟度和评价生油岩的重要指标之一。此方法具有获得结果快、设备简便、费用少等优点,因而受到人们的重视。
Since the seventies, using the sporopollen color index to determine the maturity of organic matter is a project widely carried out by oil companies abroad during the oil optics study. In the past two years, some oil census and exploration departments in China have introduced this method one after another. At present, our country is looking for deep oil and gas resources and carrying out continental shelf oil research. This calls for more rapid adoption of new technologies and new methods. In order to explore the potential of hydrocarbon generation in sediments, various indicators were used to study the maturity of oil and gas in the source rocks. Spore color is one of the most important indexes to discuss the maturity of organic matter and evaluate the source rocks. This method has the advantages of fast results, simple equipment and low cost, which has attracted people’s attention.
