摘要

针对高含水原油中大量存在的无机化合物（CaCl

MgCl2）进行研究

得出了不同比例和浓度的双组份矿化度（CaCl

MgCl2）对微波法含水率传感器检测高含水原油含水率的影响规律。利用支持向量机（SVM）对微波法含水率传感器的检测结果进行了误差校正

误差由校正前的±15. 2%减小到了±3. 47%

有效地减小了双组份矿化度对微波法含水率传感器检测精度的影响

同时为校正多组份矿化度造成的高含水原油含水率检测误差提供了方法参考和理论依据。

Abstract

The experimental study on influence of double-component salinity（ CaCl

MgCl

） abounded in hydrous crude oil to the detection precision of microwave moisture content sensor. Support vector machine（ SVM） is used to correct the results of microwave moisture sensor. The error has reduced from ± 15. 2 % to ± 3. 47 %. The influence of double-component salinity on the detection precision of microwave moisture sensor has effectively reduced. The method reference and theoretical basis for correcting the errorcaused by multi-component salinity on the moisture content detection for high water-content crude oil are provided.
