出砂是砂岩气藏开采过程中的常见问题。出砂严重时引起井壁坍塌而损坏套管,严重影响了气井的正常生产。在开发过程中如何控制气井出砂,改善浅气藏开发效果,成为至关重要的问题。
Sand production is a common problem in the exploitation of sandstone gas reservoirs. When the sand is serious, it can cause collapse of the shaft wall and damage the casing, seriously affecting the normal production of the gas well. How to control the gas sands in the process of development and improve the development effect of shallow gas reservoirs has become a crucial issue.
