【摘要】 横波资料是叠前地震反演中最重要的特征参数之一,在油气藏描述中起着关键作用。结合纵波、密度等参数衍生出其他岩石物理参数,从而较好地反映地层的岩石性质和流体特征,减少地震预测的多解性。论文从测井环境校正、岩石物理建模、计算方法、井震标定等方面研究了横波计算质量控制。应用实例进行了横波计算质量控制,得到了精确的横波资料,达到准确反映地下地质情况的目的。更多还原

【Abstract】 S-wave datum was one of the most important attribute parameters in the process of prestack seismic inversion,and it was the key parameter in geologic reservoir description.In combination with others parameters,such as P-wave and density data,many other petrophysical data were derived for better reflecting the characters of lithology and fluids and decrease the ambiguity of seismic prediction.The quality control of S-wave data calculation is studied in well logging environmental correction,petrophysical modeling,computation method and well-seismic calibration.Real S-wave data are exactly calculated to reflect the geologic reservoir.更多还原
