摘要
开展储层描述和油气预测工作,横波资料起着非常重要的作用。在测井资料中,通常缺乏的就是横波资料,这给地震波正演模拟和地震反演都带来很大的困难。文中利用常规测井资料中的声波、密度、电阻率和自然伽马曲线计算的泥质含量、孔隙度、含水饱和度等参数,在砂泥岩剖面中,同时应用标准井的全波资料,建立了某气藏的横波时差拟合模型。为计算气藏的横波速度提供了一种可借鉴的研究思路。
The data of shear wave takes a very significant part in reservoir description and oil & gas prediction. It's difficult to deal with seismic acoustic forward modeling and seismic inversion for the absence of shear wave data usually. The shear wave model of one gas reservoir was established in sand shale profile by using shale content, porosity and water saturation etc. calculated by standard well data such as acoustic wave, density, resistivity and natural gamma-ray curves. This method provides a new way to calculate the shear wave velocity of gas reservoir.
