摘要
在准噶尔盆地开展的大面元三维地震勘探,是建立在盆地实际地质条件基础上的一种创新技术。近十几年的勘探证实,这一技术在准噶尔盆地的应用中取得了巨大的经济效益。1993年彩南油田的发现,1999年陆梁油田的发现,以及漠北、石南、呼图壁、小拐、玛北、沙南、莫索湾等油气田的发现无不与大面元三维地震勘探有关。1991—2000年,在准噶尔盆地中应用这项技术探明和发现的石油储量达5.16×108t,天然气达126.2×108m3.实践表明,大面元三维地震勘探的成本远远低于常规面元三维地震勘探,不失为一种多快好省的技术。
The technology of extensive area element 3D seismic prospecting applied in Junggar basin based on real basinal geo-logic conditions is a pioneering work.In past decades,application of this technology in Junggar basin's exploration has achieved tremendous economic effectiveness.The discoveries of Cainan oilfield in1993,Luliang oilfield in1999as well as Mobei,Shinan,Hutubi,Xiaoguai,Mabei,Shanan and Mosuowan oil-gas fields are very closely re lated to the extensive area ele ment 3D seismic prospecting.During1991-2000,OOIP and OGIP proved and discovered in Junggar basin by applying this technology amount to5.16×108t and126.2×108m3,respectively.Practices indicates that the cost of extensive area element 3D seismic prospecting is much low er than that of conventional area element 3D seismic prospecting,which deserves to be a much more practical,efficient and eco nomic technology.
