The latest development of multi-interface detection sensor technology for crude oil

Petroleum is still an important source of energy and chemical raw materials in today's industrial society. Oil, water and sludge are included in the process of crude oil exploitation, and the dynamic monitoring of the interface between oil and water and oil and gas provides the basis for oil-water separation and production. In this paper, several common multi-interface detection methods for crude oil are introduced, and their advantages are analyzed and summarized. Aiming at the analysis of capacitive detection method, this paper introduces the structure and detection principle of several main capacitive sensors, and analyzes their advantages and development trend.
