Introduction
In the process of oil production and management, it is very important to constantly monitor the changes in crude oil moisture content for dynamic analysis of oil wells, control of the working conditions of oil station facilities, and mastery of the quality of exported crude oil.
The method of manual sampling and testing is currently the most popularly used for water content detection in oil fields. Both the wellhead and the oil pipeline require regular manual extraction of oil samples and sending them to the laboratory for manual testing operations. The measurement operation process requires programs such as water bath heating, rough measurement of moisture content using a graduated cylinder, sample shaking or distillation in a centrifuge, and manual calculation. Analyzing a sample takes a lot of time, and the sampling volume of this method is very small compared to the amount of liquid flowing through the pipeline. Therefore, the representativeness of the sampling is poor. The fluid obtained from manual sampling cannot represent the composition of all fluids in the oil pipeline, which results in discontinuous sampling and inaccurate reflection of the true water content of crude oil in the pipeline in laboratory results.
Therefore, traditional manual sampling methods have high randomness and can not reflect changes in the water content of crude oil in the pipeline immediately. Also traditional manual measurement methods are unable to perform accurate online measurements and cannot meet the needs of digital oilfield production management today.
Oil and water have different degrees of energy absorption for high-frequency electromagnetic waves. Due to the much higher dielectric constant of water than oil, the absorption rate of high-frequency electromagnetic waves by water is much higher than that of oil. Based on the measurement of the electromagnetic wave energy in the electromagnetic resonance cavity probe, the water content ratio in oil can be obtained after data processing and analysis.
Working Principle
The sensing probe adopts a high-frequency electromagnetic wave resonant cavity structure. This structure has the characteristics of concentrated electromagnetic wave energy inside the probe, good signal stability, low wax deposition, and is not affected by oil in water or water in oil. The excitation signal adopts a 1GHz high-frequency signal, and the 1GHz signal source has the characteristics of small frequency broadening and less impact of water mineralization on the detection results at this frequency.
