气井合理生产,关键是个控制间题。气井控制在合理压差下生产,对于保持气井稳产、减缓气井递减、延长气井寿命,提高气田最终采收率有十分重要的意义,也是气井管理的主要任务。对于象威远这样的有底水的气田来说,控制合理压差,就是要控制水对气层的侵染,尽量避免和防马水对产能的 Gas well to produce, the key is a control problem. Gas well control is produced under a reasonable pressure difference. It is of great significance for maintaining stable production of gas wells, slowing down of gas wells, prolonging the life of gas wells and increasing the ultimate recovery of gas fields. It is also the main task of gas well management. For a gas field with bottom water like Weiyuan, controlling the reasonable pressure difference is to control the water infiltration to the gas layer, try to avoid the water resistance
