摘要: 横波在各向异性地层中传播会产生分裂现象, 裂缝面与井轴平行或斜交的天然裂缝或诱导缝能够造成横波的各向异性特征, 各向异性的大小反映裂缝的发育程度, 快横波的偏振方向代表裂缝的走向。可以利用偶极声波成像测井资料提取的快、慢横波信息, 得到地层各向异性的大小, 来定性评价安棚地区裂缝的有效性和走向。

Abstract: According to the split phenomenon of shear wave transmitted in anisotropic strata, the natural or induced fractures parallel or oblique cross to a bore hole could create shear wave anisotropic characteristic. The size of anisotropy reflects the growth degree of fractures. The polarization direction of fast shear wave indicates the trend of fractures. Hence, the fast and slow shear wave information could be picked-up using dipole acoustic imaging log data, obtaining the size of anisotropy, from which the validity and trend of fractures in Anpeng area are evaluated qualitatively.

Key words: fracture, acoustic wave, shear wave, trend, anisotropy
