摘要: 描述了地震属性的拟测井反演方法,即从地震属性中反演能够反映煤层特征的拟测井曲线。该方法将钻孔处的测井曲线和地震属性作为样本数据,经过神经网络训练后形成网络模型,以此模型反演非钻孔处的地震属性,得到三维测井曲线数据体。该数据体纵向分辨率高,横向分布精确可靠,经过解释,提供高准确度的煤层空间分布情况。

Abstract: A pseudo log inversion method of seismic attribute is discussed.The pseudo log responding coal seam character was inverted from seismic attributes.The method uses log and seismic attributes of well and form a network model via neural network train,then invert seismic attributes of non-well by this model and derive 3D log data.The data is of higher resolution vertically and accurate distribution laterally,and can provide precision distribution character of coal seam by interpretation.
