[Abstract]:On-line accurate measurement of water cut in crude oil pipeline is an important data basis for analyzing the distribution of reservoir characteristics. It can monitor the production status of oil field in real time and adjust the production plan in time. It is of great significance to realize the stable production and high yield of oil fields. This paper aims at the fact that most oil wells in China have entered the stage of high water cut. In this paper, a real-time on-line water content measurement instrument based on electromagnetic induction principle is studied. A water content measurement method based on electromagnetic induction principle is put forward. The related theoretical model is established, and the theoretical calculation and simulation are carried out. Based on the theoretical analysis and simulation results, the structure of non-contact electromagnetic measurement coil is designed, and the related measuring circuit is developed. Based on the debugging of sensors, measuring circuits and upper computer software, A large number of indoor tests have been carried out for different moisture content. The research and test results show that the electromagnetic moisture content measurement system developed in this paper has reasonable structure design and good performance. A new non-contact measurement method is provided for the real-time measurement of water content in crude oil pipeline. Compared with the existing measurement methods at home and abroad, the advantage of the system is that it does not need to be contacted with the medium to be measured, and it can realize the real-time on-line measurement of water content. It has a good application prospect in the measurement of water cut in petroleum industry.
