随着现代高速数据采集系统、数据传输系统及计算机在数据处理方面应用的日益发展,使基于电磁学理论发展起来的“电法”测井在提供储集层的微小结构、沉积学和地层学资料方面,有了新的发展。本文介绍了一种最新的微电阻扫描测井仪器(MST),它可以同时测量并记录40条电流变化曲线,展示出沿着井壁变化的地层的“图像”,可以探测和定量描述只有几毫米宽的断层系统,分辨出一厘米厚的薄层,这种仪器是由道尔研究中心发明的、目前尚处试制阶段。
With the rapid development of modern high-speed data acquisition systems, data transmission systems and computers in data processing applications, the “electrical method” log developed based on the theory of electromagnetism has made great achievements in providing micro structures, sedimentology and stratigraphy of reservoirs Information, there have been new developments. This article presents a new microresistor scanning logging tool (MST) that can simultaneously measure and record 40 current curves, showing the “image” of the formation that varies along the borehole wall, and can detect and quantify only a few The millimeter wide fault system identifies a thin layer of one centimeter thick. This instrument was invented by Doyle Research Center and is still in the trial stage.
