传统的油田油气井采气嘴,一般采用金属材料制成中心带气孔的气嘴构件。存在着耐磨耐冲刷性能差、使用寿命较短、不易于控制生产压差和采气速度及平稳生产等缺点,严重影响了出砂气井正常生产,使稳产难度加大。为了解决普通气嘴在生产中刺坏率高的问题,胜利油气集输总厂开展了实用新型陶瓷气 The traditional oil and gas wells gas wells, the general use of metal materials made with a central hole nozzle components. There are shortcomings of wear resistance and erosion resistance, short service life, not easy to control the production pressure and gas production rate and smooth production, seriously affecting the normal production of sand production wells, making it more difficult to stabilize production. In order to solve the common gas nozzle in the production of thorns high rate of problems, Shengli Oil and Gas Gathering Plant launched a practical new type of ceramic gas
