摘要: 为了进一步明确中国陆上深层—超深层领域天然气勘探潜力和有利勘探目标区带分布,以及深层—超深 层天然气勘探面临的主要问题和勘探理论需求,对中国陆上深层—超深层天然气勘探资源概况与勘探进展进行梳理分 析,对中国陆上深层—超深层领域的地质特征、成藏关键要素、天然气资源潜力等进行分类评价。分析认为,中西部 叠合盆地山前带发育的库车、川西、准南等十大前陆冲断带及斜坡区是前陆冲断带领域的重点勘探区带,华北、扬子、 塔里木三大克拉通背景上发育的鄂尔多斯盆地、四川盆地、塔里木盆地古隆起及斜坡区、克拉通内裂陷及台缘带礁滩 等是深层—超深层海相碳酸盐岩领域的重点勘探区带,松辽盆地、渤海湾盆地断陷深层古隆起及斜坡区、基岩潜山是 中—新生代断陷盆地深层—超深层领域的重点勘探区带,深层—超深层火山岩等是重要探索领域。研究认为中国深层— 超深层天然气仍面临一系列问题,需要加强针对性基础攻关研究。

Abstract: In order to further clarify the natural gas exploration potentials and distribution of favorable targets, analyze the outstanding problems and improve the exploration theories in onshore deep and ultra-deep formations in China, the exploration progresses and resources were reviewed, the geology, key factors on reservoir formation and potentials of natural gas resources were classified and evaluated. Our study shows that: (1) 10 foreland thrust belts and slopes (i.e. Kuqa, West Sichuan, South Junggar, etc.) developed in the piedmont zones of the superimposed basins in mid-western China are key exploration zones in foreland thrust belts; (2) the paleo-uplifts and slopes, intracratonic rifts and platform margin reef beaches in the Ordos Basin, Sichuan Basin and Tarim Basin developed on three major cratons (North China, Yangtze and Tarim) are important deep and ultra-deep marine carbonate rock zones; (3) the deep paleo-uplifts, slopes and bedrock buried hills in the Songliao Basin and the Bohai Bay Basin are deep and ultra-deep targets in Mesozoic-Cenozoic rifted basins; and (4) others like deep and ultradeep volcanic rocks are future exploration targets. More problems should be solved, and more basic researches should be conducted related to exploration of deep and ultra-deep natural gas in China.
