Basis of petroleum geological theory and exploration direction for ultra-deep exploration of 10 000-meter depth

  • 摘要: 油气资源是关系着我国经济发展的重要战略资源。我国陆上主力油田经过50余年开采,油田含水率已超90%。我国石油和天然气对外依存度已分别由2013年的58.9%和29.2%提高到2022年的71.2%和40.2%,已进入石油安全警戒线,影响国家安全。为了寻找更多接替储量,油气勘探向“更深、更复杂”超深层的万米勘探新领域推进,近期国内油公司相继实施了“深海一号”、“深地一号”油气勘探计划,探索实践了智能导钻新技术,推动了万米勘探计划的实施,9 000 m以深的井也发现了油气藏。通过近期的勘探实践,从超深层成烃、成储与成藏机理等方面,论证了万米钻探的石油地质理论依据,指出超深层具有多途径生烃,已经突破120~160 ℃的生烃门限;“三元控储”理论指出,大于4 500 m的深层、超深层仍发育有效的储集体;多期成藏与保持是超深层规模油气藏发育的有利条件。四川盆地海相深层资源总量约为15.22×1012 m3,其绵长裂陷槽周缘震旦系、川中古隆起周缘龙王庙组、城口海槽南侧米仓山—大巴山地区龙王庙组、川西上古生界深层等具有千亿立方米的资源规模。塔里木海相深层总资源量约为152.62×108 t油当量,其中塔北隆起、塔中隆起、麦盖提斜坡的中下奥陶统岩溶以及满加尔西缘中下寒武统台缘带、阿瓦提—顺托果勒中下寒武统台内滩等是具有亿吨级规模的勘探领域。鄂尔多斯盆地西南缘的中新元古界近期也有重要的油气发现。准噶尔盆地准中深洼带、塔里木盆地库车坳陷深层等碎屑岩领域也是万米勘探的重要领域。
