| 摘 要： | 基于大地电磁静态偏移的基本原理,通过对大量实测资料的处理,提出了一种比传统静态校正方法更有效地压制静态偏移的方法---静态偏移的标定校正法.其核心内容是利用岩性测试的电性参数和测点所在位置表层或浅层地层去标定视电阻率曲线的首支,并利用人机交互式可视化静态偏移校正软件去改正视电阻率曲线.经过40多条测线共700多个测点的实际应用,证明该方法是目前较理想的静态偏移校正方法. |

| Abstract: | Based on the basic principle of magnetotelluric static migration and the processing of large quantities of measured data,this paper puts forward for suppressing static migration the standardized correction method for static migration,which is more effective than the traditional static correction method.The kernel of this technique is the utilization of lithologic electrical parameters and the surface or shallow strata at the positions of measuring points to standardize the first branch of the apparent resistivity curve,and the use of interactive visualized static migration software to correct the apparent resistivity curve.Practice shows that this method is a fairly ideal technique for static migration correction. |
| Keywords: | magnetotelluric method static migration correction standardization |
