Abstract
Modern and perspective technologies of oil production require operative and reliable data on daily productivity of oil wells separately on oil, water and gas. The complexity of solving this problem is largely determined by the composition and flow patterns of oil well products, which are known to consist of oil, produced water, associated gas and mechanical impurities. The article considers means of determining phase and component composition of heterogeneous flows, including the most promising of them - multiphase flowmeter “Neftemer”, which uses fluctuation method of measuring liquid and gas velocities in gas-liquid flow, Flowmeter is developed in the Central Research Institute of Robotics and Technical Cybernetics in St. Petersburg. The flow meter uses connections between density fluctuation parameters of oil well products and liquid and gas velocities, as well as connections between average values of output signals of multibeam radioisotope density transducer with average content of oil, water and free gas in well products.
