摘要
利用 Ｌａｍｂｅｒｔ Ｗ函数的性质，针对单发单收和单发双收两种电磁波测井仪器，给出 了一种求解视介电常数和视电导率的方法．理论分析和数值实验表明，该方法在计算速度和 精度方面，明显优于传统的求解复杂非线性方程组的方法．与查表方法相比，该方法不需要 预先计算大量图版，且精度较高．
A new method with the use of Lambert W Function is presented to solve apparent conductivity and apparent dielectric constant in electromagnetic high frequency electromagnetic well logging. Theorehcal analysis and numerical experiment show that this method has higher precision and calculating efficiency than traditional approach, in which it is necessary to solve complicated non-linear .equation system. Compared tO Chart method, this method needn't pre-calculate a lot of charts while it has higher precision.
