基于ARI测井提高双侧向电阻率曲线纵向分辨率的研究

摘要

A new method is presented to improve vertical resolution of dual lateral resistivity logs． In the light of characteristics of higher vertical resolution and deeper investigation depth of ARI logging， the nonlinear relationship between ARI curves and dual lateral resistivity logs can be set up， and also a new curve with higher vertical resolution can be created by means of BP neural network technique， the purpose of which is to enhance the ability to distinguish thin reservoirs with dual lateral resistivity logs．%夏宏泉，王拥军，杨双定等．基于ARI测井提高双侧向电阻率曲线纵向分辨率的研究．测井技术，2001，25（2）：114～118rn介绍了一种提高双侧向电阻率测井曲线纵向分辨率的新方法。该方法根据方位电阻率成像（ARI）测井具有较高的垂直分辨率和较大的探测深度等特点，借助于BP神经网络技术，实现方位电阻率成像测井与常规双侧向电阻率测井之间的非线性标定，并构成1条高分辨率的电阻率曲线，旨在提高常规双侧向电阻率测井分辨薄层的能力。
