摘要:
2016-2018年期间, 由中国地质调查局油气资源调查中心牵头组织实施的"全国油气资源战略选区调查工程", 以实现"新区、新层系、新类型、新认识"四新领域油气调查战略发现和突破, 推动创建油气勘查开发新格局为目标, 按照总体部署、分步实施原则, 组织开展了长江经济带页岩气调查、北方新区新层系和松辽盆地页岩油调查油气调查三大科技攻坚战.在基础地质调查基础上, 评价优选了一批页岩油气有利目标区, 部署实施了二维地震、参数井和压裂试气工程, 实现了长江中游下古生界页岩气、松辽盆地白垩系青山口组页岩油、塔里木盆地温宿凸起新近系油气、准噶尔盆地南缘二叠系芦草沟组油气和侏罗系西山窑组煤层气以及银额盆地居延海坳陷石炭系—二叠系油气调查等一系列重大突破和发现, 初步摸清了新区新层系资源潜力.这些成果大大提振了南方复杂构造区页岩气、陆相页岩油和北方新区新层系油气资源勘查的信心, 推动了油气地质调查与科技创新的深度融合, 形成了油气成藏理论机理新认识, 发挥了公益性油气资源调查的引领和带动作用.
Abstract:
The "National Oil and Gas Resource Strategic Constituency Survey Project" led by Oil and Gas Resources Survey Center, China Geological Survey during 2016-2018, aims to realize the strategic discovery and breakthrough of oil and gas investigation in four new fields of "new district, new stratum, new type, new understanding", and promote the new pattern creation of oil and gas exploration and development. According to the overall deployment and step-by-step implementation principles, the project organized three major scientific and technological battles, including the shale gas survey in Yangtze River Economic Belt, the shale oil survey in Songliao Basin and the oil and gas survey in the new strata of northern new area. On the basis of basic geological survey, the project evaluated a batch of favorable shale oil and gas target areas, and deployed two-dimensional earthquakes, parameter wells and fracturing gas test projects. The project initially found out the resource potential of the new strata in northern new area, and realized a series of major breakthroughs and discoveries in the Lower Paleozoic shale gas in the middle reaches of Yangtze River, the Cretaceous Qingshankou Formation shale oil in Songliao Basin, the Neogene oil and gas in Wensu Sag of Tarim Basin, the Permian Lucaogou Formation oil and gas in the southern margin of Junggar Basin, the Jurassic Xishanyao Formation coalbed methane, and the Carboniferous-Permian oil and gas in Juyanhai Depression of the Yin'e Basin. These achievements have greatly boosted the exploration confidence in the southern complex structure area shale gas, continental shale oil and the northern new strata oil and gas, and promoted a deep integration of oil and gas geological survey and scientific and technological innovation, forming a new theoretical mechanism of hydrocarbon accumulation. The project played a leading role in the investigation of public welfare oil and gas resources.
