【摘要】：地震叠前深度偏移技术是目前油气勘探、开发、科研和生产中应用的关键技术。结合胜利油区在叠前深度偏移技术方面的研究、应用成果及经验,首先介绍面向研究区块地表和地下地质情况的特色化实用叠前深度偏移与建模技术,在不同区块和地质任务的应用中,这些技术可以根据需求配套使用。其次,从采集—处理—解释一体化的思路出发,分析了叠前深度偏移技术的影响因素,并提出了针对性的解决对策。最后,通过几个典型区块的工业化应用实例验证了胜利油区叠前深度偏移技术一体化解决方案的效果,总结出一套"深度域+"的叠前深度偏移技术研究思路,进一步推动深度域地震技术的发展,更好地为油气田勘探和开发服务。
[Abstract]:Seismic prestack depth migration is a key technology in oil and gas exploration, development, scientific research and production. Combined with the research of prestack depth migration technology in Shengli oil area, and the application results and experience, this paper first introduces the characteristic and practical prestack depth migration and modeling technology for the surface and underground geological conditions of the study block. In the application of different blocks and geological tasks, these technologies can be used in accordance with demand. Secondly, based on the idea of the integration of acquisition, processing and interpretation, this paper analyzes the influence factors of prestack depth migration technology, and puts forward some countermeasures. Finally, the effect of integration solution of prestack depth migration technology in Shengli oil area is verified by several typical industrial application examples, and a set of research ideas of prestack depth migration technology in "depth domain" are summarized. Further promote the development of seismic technology in depth domain, and better serve the exploration and development of oil and gas fields.
