摘　　要：从地层岩石物理性质—测井响应—地震响应分析角度,介绍了利用现有各种测井曲线与声波曲线,合成拟声波曲线,弥补常规声波测井的不足,来提高地震反演的分辨率,以便更准确地进行储层预测。从拟声波曲线与录井地层剖面对比,拟声波曲线地震地质层位标定,拟声波曲线地震宽带约束反演实际应用等方面进行拟声波曲线应用效果检查分析表明,拟声波曲线构建技术的应用可以很好地提高地震储层反演的分辨率和精度。今后,拟声波曲线会得到更广泛的应用。This article introduces,based on the analysis of physical properties of formation rocks and their responses in well logging and seismic,using all available well logging curves and acoustic curve to compose a pseudo-acoustic curve to offset the disability of acoustic curve in order to improve the resolution of seismic data and finally to predict reservoirs in a more accurate way.The analysis to the performance efficiency of pseudo-acoustic curve in the correlation between sections of pseudo-acoustic curve and lithologic sections from logging,in the marking of geological formation with seismic pseudo-acoustic curve, and in the application of restriction inversion of seismic bandwidth of pseudo-acoustic curve indicates that the using of the techniques of composing pseudo-acoustic curve can greatly improve the resolution and accuracy of reservoir seismic inversion.Afterwards,pseudo-acoustic curve will be used more broadly.
