摘要
根据苏北地区大地电磁勘探环境特点进行了电极距长度、磁场位置和采集时长的试验工作,确定了大地电磁测深勘探技术参数设置下限,电极距长度不能小于50m,采集时间要大于8h,磁距应控制在2km范围内。
Based on the environmental characteristics of magnetotelluric exploration in North Jiangsu, trial study on electrode spacing, magnetic position and data collection time is conducted, and the lower limit of technical parameters is set for exploration technology of magnetotelluric sounding. It is concluded that the electrode spacing is not allowed to be less than fifty meters, data collection time should be longer than eight hours and magnetic space should be controlled within the scope of two kilometers.
