摘要: 在叠前弹性阻抗反演中,由于常常缺乏横波时差测井资料,导致不能准确地计算岩石的泊松比。针对这一问题,充分利用井的纵波时差、地层密度、泥质含量、孔隙度、含水饱和度等常规测井资料以及岩石骨架和流体的各种弹性参数等构建流体置换的Xu-White 模型,用以计算横波时差。将该方法应用于MBTL 地区M 区块的PMNA-001 井以及另一F 区块的F18B-29 井、F18B-116 井的横波时差的计算,结果表明,与实测横波时差相比,误差较小,完全能满足横波弹性反演和油气预测的需求。

Abstract: In the pre-stack elastic impedance inversion, since the shear wave time difference log data are frequently not gained, the rock Poisson ratio cannot be accurately calculated. For this reason, the compressional wave time difference, formation density, shale content, porosity, water saturation and a variety of rock matrix and fluid elastic parameters are sufficiently used to develop Xu-White model for fluid displacement and get the shear wave time difference. This method is used for calculation of shear wave time differences of Well PMNA-001 at M block, Well F18B-29 and Well F18B-116 at F block in MBTL area. The results show that compared with the actually measured shear wave timedifference for these wells, the errors are small, completely meeting the demands of elastic wave inversion and oil-gas prediction.

Key words: rock, Poisson ratio, shear wave time difference, compressional wave time difference, formation density
