摘　　要：井筒积液会使气井正常生产受到影响,严重时会导致水淹而停产,目前现场常用气井积液预测的临界携液流量模型均有一定的局限性。为了更准确地预测涩北气田气井临界携液流量,根据椭球模型,推导出适合涩北低渗透气田的临界携液流量模型。Well bore fluid will affect the normal production of gas wells,and even cause water to be flooded and production shut down. The commonly used critical carrying fluid flow model has some limitations. In order to predict the critical liquid carrying capacity of gas wells in the Sebei gas field more accurately,a critical liquid carrying flow model suitable for low permeability gas fields in Sebei is derived in this paper,based on ellipsoid model.
