Principle of depressurization technology for screw pump mixed flow pump

During the oil field process, it is necessary to collect and transport multiphase mixtures containing oil, gas, water, and impurities directly extracted from oil wells. The gas-liquid ratio of this mixture has exceeded the working range of ordinary pumps and compressors, resulting in a significant decrease in the efficiency of pumps and compressors during gathering and transportation. Although the use of oil and gas separation can solve the problems encountered in these oil fields, the construction of separators and oil and gas pipelines will increase investment and operational management. The use of multiphase oil and gas mixing technology can solve this problem, and oil and gas mixing pumps are the core of oil and gas mixing technology. Oil well production is often accompanied by a large amount of gas, water, and solid particles. In order to reduce wellhead backpressure, increase crude oil production, improve efficiency, and achieve the goal of closed oil and gas transportation, a multiphase mixed flow pump is used to pressurize and transport multiphase mixed media such as oil and gas, in order to use the energy of the mixed flow pump to reduce the pressure of the front-end system of the process.
