摘　　要：针对煤层气井用射流泵返排压裂液效率过低的问题,基于RNGκ-ε湍流模型和Mixture多相流模型分析了砂粒直径对射流泵内流场、压力和效率的影响,并开展了相似参数准则实验。研究结果为射流泵应用于油井除砂排放工程提供了一定的理论指导。Aiming at the problem that the efficiency of fracturing fluid flowing back by jet pump in coalbed methane well is too low,based on RNG κ-ε turbulence model and Mixture multiphase flow model,analyzed the influence of sand particle diameter on the flow field,pressure and efficiency of jet pump,and carried out indoor similar parameter criterion experiment. The research results provide a certain theoretical guidance for the application of jet pump in oil well desanding and drainage engineering.
