Put forward is a new method of skin effect correction based on function relationship between the real part of apparent conductivity against frequency and true formation conductivity in uniform formation condition.
根据均匀地层感应测井视电导率实部与频率和地层电导率的函数关系提出了一种双频率校正与归一化校正相结合的趋肤效应校正新方法。
A formula to estimate the apparent conductivity and sea ice thickness has been obtained after the correlation analysis of the EM apparent co.
通过电磁感应(EM)仪观测的视电导率与同点位钻孔测量数据对比分析,获得视电导率与海冰厚度的换算关系式,通过对用该关系式计算出的海冰厚度进行验证,表明电磁感应技术能够获得可靠的海冰厚度数据。
The multiplying adding factor method must divide apparent conductivity into many segments and the function fitting method must select appropriate fitting function.
传统的感应测井趋肤效应校正方法包括乘加因子法和函数非线性拟合法,乘加因子法需要对视电导率曲线进行分段,函数非线性拟合法则要选取合适的拟合函数,这两种方法均含有人为因素,误差较大,不具备通用性。
