| 摘 要： | 碳酸盐层储层中普遍存在各向异性，利用横波在各向异性地层中分裂成快速横波和慢速横波的原理，可以定量计算各向异性的大小，进而进行各向异性分析，给出了利用斯伦贝谢公司偶极横波成像（ＤＳＩ）的ＢＣＲ资料来确定地应力方向和识别有效裂缝及其走向的实例。

| Abstract: | Formation anisotropy exists commonly in carbonate reservoir. Based on the principle that S wave is normally splitted up into fast and slow S waves in anisotropic formation, quantitative computation of anisotropy can be made, and hense, anisotropy analysis is improved. Given herein is how to determine the direction of formation stress, effective fractures and its strike according to BCR data from DSI (Dipole Shear Sonic Imager). |

| Keywords: | anisotropy shearwave splitting stress fracture identification formation evaluation |
