针对黄土塬地震勘探这一世界级难题,回顾了黄土塬地震勘探历程,介绍了黄土塬地震采集、处理、解释关键技术,总结了长庆油田分公司在鄂尔多斯盆地黄土塬三维地震勘探成效和取得的主要油气勘探成果,梳理了鄂尔多斯盆地不同探区、不同类型油气藏勘探开发对黄土塬地震勘探的技术需求.长庆油田油气勘探开发实践结果表明,经过几代人50年攻关形成的黄土塬特色的"两宽一高一单点"三维地震勘探技术,有力支撑了长庆油田油气勘探重大发现、大规模增储和高效建产.下一步将以油气需求驱动为目标,瞄准三维地震"高精度、高效率、低成本、智能化"发展方向,持续攻关完善黄土塬地震技术系列,坚持原创技术引领与适用成熟技术推广结合,更有效支撑长庆油田分公司6 600× 104 t上产稳产.
The loess tableland of the Ordos Basin is a world-famous challenging area for seismic exploration.In this paper,we re-viewed the history of seismic exploration in the loess tableland,key techniques of seismic data acquisition,processing and interpre-tation,application results of 3D seismic techniques in the loess tableland and major achievements of hydrocarbon exploration by Changqing Oilfield Company,and technical requirements for seismic exploration targeting different reservoir types in different prospect areas of the Ordos Basin.After 50 years of hydrocarbon exploration and development by several generations of people,3D seismic techniques featuring wide azimuth,wide band,high density,and individual-geophone receiving have become strong support to major discoveries,great reserves increase,and high-efficiency production in Changqing Oilfield.Aiming at oil and gas demand,3D seismic techniques should evolve toward the direction of high precision,high efficiency,low cost,and intelligence based on sus-tained efforts.Innovative techniques should be combined with proved techniques to effectively support stable production of 6 600X 104 t by Changqing Oilfield Company.
