摘要
崖13-1气田是迄今为止中国发现的最大气田.根据其气体组份、同位素资料、轻烃及汞含量等分析资料,认为崖13-1天然气具有煤层气的典型特征,而间接(气-油-岩)和(气-岩)对比表明,崖13-1的气和凝析油均来自崖城组的含煤地层.此外该含煤地层的有机质丰度,类型及成熟度均表明其具有煤层气和煤成油的潜力.
Ya 13—1 gas pool is the biggest gas discovery ever made in China so far. Based on analvtical dta of the natural gas components, isotopics (d^(13)C_(1),δ^(13)C_2,δ^(13)C_(CO_2),δD_(ch1)), light hydrocarbons, mercurv content, it is believed that the gas there has characteristically the properties of coal—formed gas. According to indirect correlation (gas—oil—rock) and direct correlation (gas—rock), it is inferred that both the gas and the condensate are originated from Yacheng formation. The abundance type and maturity of organic matter as well as migration pattern all indicate that Yacheng coal bearing formation had potential of generation of gas and oil and thus must have been responsible for the gas accumulation.
