摘要
SAMT法在测量过程中的静态效应问题一直是电磁测深领域的难题,正确识别静态效应,及时对测量资料进行处理是保障勘探工作顺利进行的关键.为了掌握CSAMT测量中静态效应的特征,通过正演模拟的方式,从静态体的埋深和电阻率高低等方面研究了静态效应,讨论了不同极化模式、偶极长度、测点位置、测量频段对静态效应的影响.初步掌握了静态效应的规律,有助于实际勘探资料中静态效应的识别和采取有效的方法消除静态效应.
The problem of static effects in the process of CSAMT is difficult to solve in the electromagnetic sounding field.Correctly identifying static effects and timely treating measurement data are crucial to ensure exploration work being conducted smoothly.In order to grasp the characteristics of static effects in the process of CSAMT,through the way of forward modeling,we study static effects from the area of static body depth and resistivity value,and discuss the effect of different polarization modes,dipole lengths,the location of measurement points and measurement frequency on the static effects.The law of static effects is initially grasped,and it is helpful to identify static effects in actual exploration data and adopt effective measures to eliminate static effects.
