摘　　要：随着油气勘探开发的不断深入,勘探目标主要为中深层复杂断块油气藏、岩性油气藏以及地层油气藏等隐蔽性油气藏,相应的油气勘探开发难度越来越大。由此对地震成像的精度自然提出了更高的需求。本文就如何提高地震成像的精度阐述了强化地震第一手资料的质量、新老成像方法的针对应用、叠前数据优化、资料保幅处理、质量分析与监控以及研究资料体处理方法的几点思考。希望对地震资料处理研究人员起到一些借鉴与参考作用。With the deepening of oil and gas exploration and development, the main exploration targets have become the subtle reservoirs, such as the complex fault block reservoir, lithologic reservoir, stratigraphic reservoir and so on in the deep, the oil and gas exploration also become more difficult. Thus the accuracies of seismic imaging are required higher standards. This article proposes some thoughts how to improve the accuracy of seismic imaging： strengthening the quality of first hand seismic data, the application of the old and new imaging methods,prestack data optimization, data preserved amplitude processing, quality analysis and control, data volume processing method. Hope it could provide some reference with the seismic data processing researchers.
