摘要
本文从高频感应测井仪器(VIKIZ)的线圈系结构及其工作原理出发,研究了仪器响应中井眼和偶极子模型的影响,获得了井眼校正方法和偶极子校正方法.同时提出了从高频测量信号中提取介电常数方法.研究表明,在盐水泥浆情况下,井眼因素对测井响应的影响不能忽略,要进行井眼校正.研究成果针对理想地层模型进行了验证,所开发处理软件已经成功用于处理实际测井资料中.
Based on the coil structure and its working principle of the High-Frequency Induction Logging Isoparametric Sounding （VIKIZ）, this paper studies the effects of the borehole and dipole model on the instrument response. The corresponding correction methods are proposed, and dielectric constant is extracted as a result of analysis of high frequency signal. The study has shown that in salt mud boreholes, the effects of the borehole cannot be neglected and need to he corrected. The theory has been validated by the modeling and the resulting code has been successfully applied to logging data.
