传统三维地震资料解释方法在构造油气藏的勘探研究中发挥了重要作用,但对于岩性油气藏的勘探研究则缺乏有效的手段。针对这个问题,该文提出了一种新的地震资料解释方法——地震平面沉积相解释方法,它是在地震切片解释方法的基础上,发展了多属性融合成像、切片沉积相投影、平面沉积相智能追踪等关键技术,这些技术充分利用了地震资料横向密集连续的特性,提高了地震-地质解释的效率和精度,对地下规模较小的地质体具有很好的识别能力,对岩性油气藏的勘探和研究具有借鉴作用。

Traditional three-dimensional seismic interpretation has a good effect on the exploration research of structure reservoir, but it can not solve the problem in the exploration and study of lithologic reservoir. This paper proposed a new seismic interpretation method： plane sedimentary facies interpretation. Based on the method of seismic slice interpretation, it develops the key technologies such as multi-attribute fusion imaging, projection of slicing sedimentary facies and auto-tracking of plane lithofacies. These technologies fully use the characteristics of lateral continuity, and can improve the efficiency and accuracy of seismic-geologic interpretation and have recognition capability for small geologic bodies and significance for exploration and study on lithologic reservoirs.
