摘要

双频感应测井仪的误差校正处理是整个仪器设计的关键一环,对后续的信号幅度比和相位差数据处理,以及正确评价地下油层信息具有非常重大的意义。首先描述了双频感应测井仪工作的理论基础,通过分析仪器线圈系的磁偶极子模型寻找到误差的来源;然后基于误差分析方法,提出了一种测量该系统误差的方法并予以电路实现;最后在模拟的现场环境中,进行误差测量与仪器修正值的确定。实测结果表明,该方法能够明显提高仪器测量相应曲线的准确度,达到误差校正的目的。

Abstract

The error correction of Dual-Frequency Induction Tool (DFIT) is a key link in the design of subsequent data processing on signal amplitude and phase difference, and also it is great importance in the correct evaluation of underground reservoir. The theory of the DFIT is described and the error source is found by the analysis of magnetic dipole model on this instrument coils. A method for measuring the system error and also the circuit implementation are proposed based on the error analysis method. Finally in the field of environmental simulation, the error of measurement and the correction of the instrument are determined. It is showed that this method can obviously improve the accuracy of the measuring instruments to achieve the purpose of error correction in the experimental results.
