摘要: 为了明确出砂对气井临界携液流量的影响，优选出适合现场的临界携液流量模型并进行修正，通过配制与实际气田地层水相同矿化度的液体介质及筛选现场目数相同的砂粒，进行室内气流携液携砂模拟实验，最终建立了出砂情况下气井临界携液流量新模型。现场实际数据验证发现，新模型具有良好的精度，且在出砂情况下新模型积液判断更加贴合实际情况。新模型可为出砂气井的生产设计提供理论指导。
Abstract: In order to clarify the influence of sand production on the critical liquid carrying flow rate of gas wells, the critical liquid carrying flow model suitable for the site is optimized and corrected. The liquid medium with the same salinity as the actual gas field formation water and the screen number of the screening site are the same. The sand particles were subjected to the simulation experiment of carrying air in the indoor air stream, and finally a new model of the critical liquid carrying flow rate of the gas well was established. The actual data verification at the site found that the new model has good accuracy, and effusion judgment of the new model is more suitable for the actual situation in the case of sand production. The new model provides theoretical guidance for the production design of sand production wells.
