井周介质各向异性参数反演方法与应用

Inverse Methods and Application of Anisotropy Parameter of Media Around the Borehole

采用 Alford矩阵旋转方法和线性变换方法对交叉偶极阵列声波测井仪器录取的资料进行井周介质各向异性方向和大小的反演进行研究 .通过对计算机合成数据的处理 ,检验了方法的正确有效性 ,比较了两种方法的特点 .将反演程序用于现场实际数据处理 ,得到了满意的反演结果 .

Alford matrix rotation and linear transformation methods have been studied and used to inverse the data acquired by advanced cross-dipole acoustic array logging tool. From the data inversion we gained the direction and the quantity of the anisotropy of the media around the borehole. The validity of the inversion methods and the programs have been verified through processing synthetic data and the features of these two methods has been compared. The inversion programs have been applied to processing field data and the results of inversion are satisfactory.
