我们采用2D快速反演算法检验了不同的电阻率/IP排列的分辨率合成数据中含有噪声,并经过了最小构造反演处理。找们对用偶极一偶极,单极一偶极,以及单极一单极排列数据反演后估算的模型进行了对比,四个目标体为:(1)倾斜的可极化导体;(2)两个近似导电极化体;(3)导电覆盖层之下的极化导体;(4)薄电阻率极化岩脉。估算的电阻率与用偶极一偶极数据反演获得的极化模型常常与单极一偶极估算模型相似。在所考察的实例中,由单极一单 We used 2D fast inversion algorithm to test the different resistivity / IP array resolution with noises in the resultant data and the least inversion of the structure. We compare the models estimated with dipole-dipole, monopole-dipole, and unipolar-monopole array inversion. The four targets are: (1) a tilted polarizable conductor; (2) two approximately conductive polarizers; (3) polarized conductors beneath the conductive coating; and (4) thin resistivity polarized dikes. The estimated resistivities are often similar to the unipolar-dipole estimation model for polarizations obtained with dipole-dipole data inversion. In the investigated example, from a single pole to a single
