目前,国外主要煤层气国家仍坚持在浅层煤层气中缓慢发展,但中国在深层煤岩气上,已经取得突破性 进展。基于"借鉴页岩气生储富集机制,将煤岩作为储层整体勘探"的创新理念,中国石油天然气集团有 限公司率先在鄂尔多斯等盆地取得勘探战略性突破。2021年以来,中国石油在大吉区块开展深层评价, 23口水平井初期平均单井日产超10万立方米,先导试验取得成功,展现了良好发展前景,开辟了煤岩气 发展新领域,2024年,煤岩气荣获中国石油勘探重大发现特等奖,鄂尔多斯盆地成为煤岩气工业化 的"革命圣地"。与此同时,国内其他两家国有石油公司也取得深层煤岩气突破。 煤岩气这种新类型的非常规天然气,与传统煤层气一样,都产自地下煤岩地层。但它有着热演化程度 高、生气量大且游离气占比高的独特特征。它的储层类型和煤层气类似,赋存特征又和页岩气相近,开 发方式则与页岩气、致密气相似。鉴于这种新类型的非常规天然气与传统煤层气在地质特征、成藏机理 和开发方式上具有明显的差异,根据勘探开发实践的需要,中国石油提出了"煤岩气"概念。中国煤岩气 革命历经四个阶段:从"瓦斯气"到"煤成气"到"煤层气"再到"煤岩气"。煤岩气或是近百年以来,中国人 首次在化石能 ...
煤岩气开辟天然气增长新领域 全国探明地质储量超7000亿立方米

新华财经北京11月13日电(记者安娜) 近期,一种被命名为"煤岩气"的新型非常规天然气资源勘探开 发捷报频传,成为我国天然气增产的新亮点。中国石油集团13日提供的数据显示,截至2025年10月底, 全国煤岩气累计探明地质储量已超7000亿立方米。 2025年3月,中国石油代表团在第43届"剑桥能源周"上,向全球正式发布了"煤岩气"的概念与地质理 论。煤岩气究竟是什么?它和人们熟知的煤层气有何不同? 据中国石油勘探开发研究院有关负责人介绍,传统煤层气以"吸附"状态为主,而煤岩气则是"游离态和 吸附态并存",且"游离气含量高"。它呈现出一种跨界特征:赋存特征接近页岩气,开发方式则与页岩 气、致密气相似。鉴于这种显著差异,中国石油勘探开发研究院研究团队根据勘探开发实践需要,正式 提出了"煤岩气"(Coal-rock Gas, CRG)这一全新概念。 这一重大理论创新的背后,是更宏观的"全油气系统"理论的支撑。传统石油地质学理论在解释无明确边 界的非常规油气时存在局限。中国科学院院士贾承造于2014年提出"全油气系统"理论,用统一的视角将 常规与非常规油气资源统摄于一个完整体系中。在此框架下,中国石油勘探开发研究院的 ...
