摘　　要：安山岩分布研究是火成岩油藏有利储层研究的基础,是确定有利目标最直接的地质依据。从火山岩喷发模式、火山口识别入手,利用沿层地震属性,从宏观上定性预测安山岩的分布。利用多井测井约束反演对岩性展布特征进行定量预测。利用神经网络多属性反演技术进一步提高地震反演精度,实现对安山岩平面分布的认识。The study of andesite distribution is the basis of the favorable reservoir of igneous reservoir, and the most direct geological basis to determine the favorable target. The distribution of andesite is predicted qualitatively by the seismic attributes along the layer from macroscopic view based on volcanic eruption model and crater recognition. The multi-well logging constraint inversion is used to quantitatively predict lithologic distribution characteristics. The neural network multi-attribute inversion technique is used to further improve the accuracy of the seismic inversion and realize the understanding of the horizontal distribution of the andesite.
