井中脉冲电磁法,亦称井中瞬变场法或井中过渡过程法,主要是研究不接地迴线在脉冲间歇产生的非稳磁场,其理论基础是麦克思韦方程.为了推广井中脉冲电磁法在我国的应用,我们于1983年,用本院研制的DMD—Ⅱ型脉冲电磁仪,对不同参数的球、柱、和板状体做了测井模型研究.现取其较为典型的部分模拟曲线(主要以板状体为例)将其结果作简要
In-well pulsed electromagnetic method, also known as transient well field method or in-well transient process method, is mainly to study the ungated magnetic field produced by the ungrounded line during intermittent pulse. The theoretical basis is Maxwell’s equation. In order to promote the well-pulse electromagnetic method China’s application, we used in 1983, DMD-Ⅱ pulse electromagnetic instrument developed by our hospital, different parameters of the ball, column, and plate-shaped body made a logging model. Now take some of its more typical analog curve (Mainly plate-shaped body, for example) to the results for a brief
