摘　　要：鄂尔多斯盆地是我国第二大沉积盆地,油气资源丰富,勘探前景广阔,是我国近20年来石油天然气储量、产量增长最快的盆地,目前已成为我国第一大油气生产盆地和第一大天然气产区。长庆油田通过50多年的攻关研究,创新发展了“陆相淡水湖盆页岩油、内陆坳陷湖盆大型三角洲、侏罗系古地貌油藏群、陆相致密砂岩气、奥陶系岩溶古地貌天然气”等5项油气地质认识,形成了“黄土塬三维地震勘探、低渗透致密油气层测井识别与评价、低渗—致密储层体积压裂”等三大技术系列,发现了4个10亿吨级大油区和3个万亿立方米大气区,为保障国家能源资源安全做出重要贡献,同时对国内外其他类似盆地的勘探提供了重要经验与借鉴。Ordos Basin is the second largest sedimentary basin in China,which has abundant oil and gas resources and broad exploration prospect.In recent two decades,growth in oil and gas reserves and production is the fastest in Ordos Basin,and now it is the largest oil and gas producing basin and the largest natural gas producing region in China.Through more than 50 years of research,Changqing Oilfield has innovated five petroleum geological understandings,including"shale oil of continental freshwater lake basin,large delta of inland depression lake basin,Jurassic paleogeomorphic oil reservoir group,continental tight sandstone gas,and Ordovician karst paleogeomorphic natural gas".Moreover,three technology series have been developed in terms of"3 D seismic exploration in loess plateau,logging identification and evaluation technology of low-permeability tight oil and gas layers,and volume fracturing of low-permeability tight reservoir".As a result,four billion-ton-level large oil regions and three trillion-cubic-meter-level large gas regions have been discovered,contributing a lot to the national energy and resource security and providing important experience and reference for the exploration of similar basins at home and abroad.
