地震平面岩相解释方法的研究及应用

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具有针对性的手段。本文提出了一种新的地震资料解释方法——地震平面岩相解释,它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、平面岩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重要意义。

The research and the application of plane lithofacies interpretation

The traditional three-dimensional seismic interpretations have good effects on structural reservoir, but they cannot solve the problem in the exploration and study of lithology reservoir. In this paper, a new seismic interpretation method——plane lithofacies interpretation was proposed, which was based on the seismic slice interpretation methods and has developed the key technologies such as multi-attributes fusion imaging, the projection of slicing sedimentary facies, the auto-tracking of plane lithofacies ,and so on. These technologies can fully use the horizontal intension feature of seismic data to improve the efficiency and accuracy of seismic-geological interpretation for identifying effectively small subsurface geological body. It proves that the Plane lithofacies interpretation is an efficient and accurate method of seismic data, having an important significance for the exploration and the research of lithology reservoirs.
