摘要
基于近红外光谱吸收原理和光纤传感器技术，提出了用于原油低含水率测量的方法和实验系统。该方法具有测量速度快，精度高，对油品无污染，适合于长期在线连续测量的特点。特别适合于油田转油站、脱水站、联合站等生产单位对原油的含水质量检测和生产过程控制要求较高的场合。在体积含水率0～5％的测量范围内，体积含水率的测量分辨率好于0．005％，体积含水率0～1％范围内的测量误差可达±0.01％。
Based on near-infrared spectral absorption and fiber-optic sensor technology, an experimental setup for low-water-content measurement of crude oil is developed. The advantages of this method include fast measurement, high accuracy, being free of pollution to measured oil, and being suitable for long-term on-line continuous monitoring. This technology can be used for those applications which have high quality water-in-oil measurement and process control requests. The measurement resolution of water-content can be estimated to be better than 0. 005 % in the range from zero to 5% by volume, and ±0.01% in range of zero to 1%.
