三维自然电位测井的数学模型与求解方法
Mathematical Model and Numerical Method for 3D Spontaneous Potential Well-logging
摘要
Abstract
In this paper,a mathematical model is presented for 3D spontaneous potential well-logging,and the foundations of its theories and algorithms are provided.Numerical simulations based on the finite element method show that:Compared with the commonly used axisymmetric model with the measuring electrode centered in the borehole,the 3D model with the measuring electrode attached to or near the borehole wall can effectively improve the well-logging quality,especially for the thin objective layer.关键词
