| 摘 要： | 目前Schlumbeger提供11张图版用于ARC仪器的围岩校正,利用这些图版校正的优点是操作简单,快捷,但图版数量少且不考虑井轨迹与地层角度变化,适用范围有限。本文从测井仪器响应出发采用反演的方法对围岩进行校正,适用于各种条件下的围岩校正,应用实例表明,该法结果可靠,具有较好的应用价值。

SURROUNDING ROCK INVERSION CORRECTION OF LOGGING-WHILE-DRILLING RESISTIVITY LOGGING |

| Abstract: | Schlumbeger has provided 11 plots for surrounding rock correction of ARC tool.These plots have advantages of simple and fast operation. But there are less plots without regard for well trace and angular change of formation.They are restricted in application.The paper introduces an inversion method to correct the surrounding rock from logging tool response which can be used in different kinds of conditions. Cases indicate that it is reliable and has good application value. |
