大面元三维地震勘探在准噶尔盆地的成功实践

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。

On Successful Practices for Large Bin 3D Seismic Prospecting in Junggar Basin

The technology of extensive area element 3D seismic prospecting applied in Junggar basin based on real basinal geologic 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 in 1993, Luliang oilfield in 1999 as well as Mobei, Shinan, Hutubi, Xiaoguai, Mabei, Shanan and Mosuowan oil-gas fields are very closely related to the extensive area element 3D seismic prospecting. During 1991-2000, OOIP and OGIP proved and discovered in Junggar basin by applying this technology amount to 5.16x108t and 126.2x108m3, respectively. Practices indicates that the cost of extensive area element 3D seismic prospecting is much lower than that of conventional area element 3D seismic prospecting, which deserves to be a much more practical, efficient and economic technology.
