摘　　要：稀疏脉冲波阻抗反演的基本假定条件是 ,地层的反射系数稀疏的。在构造和测井约束的条件下计算宽带波阻抗 ,进而与测井、地质资料对比 ,求出三维工区目的层的储层厚度。该方法在YX油田滚动勘探开发跟踪预测研究中 。On the assumption that the reflection coefficients of formation are sparse, the sparse impulse impedance inversion calculates wide-band impedance under the constraints of structure and log data, and gains reservoir thickness of 3D working areas by correlation with the results from log and geology. Notable effects have been reached by applying the method to the tracing prediction for progressive exploration and development in YX oil field.
