Abstract

In petrochemical production, the flow of oil-water mixture in pipelines is a common phenomenon referred to as oil-water two-phase flow. The main purpose of oil-water two-phase flow detection is to detect the proportion of oil or water in the liquid to be tested, which is significant for crude oil extraction, storage and transportation and even sales. This article analyzes the impact of complex environments on the detection results of oil-water two-phase flow and introduces the basic principle of oil or water content detection methods in oil-water two-phase flow detection as well as the applicability, advantages and disadvantages of various detection methods. Then the domestic and foreign scholars’ efforts toward the fundamentals are briefly introduced. Finally, existing methods are summarized, together with research trends for oil-water two-phase flow.
