摘　　要：针对目前国内在油田水水质监测方面存在诸多技术问题,应用多波长融合技术(不同组分采用不同波长光波测量,不同波长之间的测量互不影响)、嵌入式探头设计技术(有效缩小设备尺寸,方便安装,实现实时在线测量)、温度补偿技术(消除温度对测量的影响)、探头加温技术(防止内外温差对探头的损坏),对油田回注水水质在线监测技术和仪器设计进行了研究。结果表明,建立了油分和悬浮物在线同步测试模型,提出了“先荧光后散射”的测量方法,在一套光路系统中同步实现了油分和悬浮物浓度的检测;采用嵌入式探头设计,实现了污水水质的实时在线连续测量;充分考虑石油化工污水管道工作环境,消除温度、湿度等因素对测量的影响,通过多重措施保证仪器测量精度。In view of the current domestic oilfield water quality monitoring in many technical problems, the application of multi-wavelength fusion technology (different components using different wave-lengths of light wave measurement;the measurements between different wavelengths do not affect each other), embedded probe design technology (effectively reduce the size of the equipment, con-venient installation, realize real-time online measurement), temperature compensation technology (eliminate the influence of temperature on measurement), probe heating technology (prevent in-ternal and external temperature difference to probe damage), the oil field reinjection water quality online monitoring technology and instrument design were studied. The results show that the on-line synchronous testing model of oil and suspended matter is established, and the measure-ment method of “fluorescence before scattering” is proposed. The detection of oil and suspended matter concentration is realized synchronously in a set of optical path system. The embedded probe design realizes the real-time on-line continuous measurement of sewage quality. Fully considering the working environment of petrochemical sewage pipelines, eliminating temperature, humidity and other factors on the impact of measurement, the accuracy of the instrument measurement is ensured through multiple measures.
