Velocity 管柱通过石盐沉积恢复深层气井的生产

本文介绍了通过安装速度管柱来处理石盐沉积的深层气井,该速度管柱在气井反液化和石盐管理之间产生协同作用。

完整的论文描述了这样一种情况:在通过耗尽压缩降低系统压力后,超过 150 个深层气井开始出现岩盐沉积。许多存在此问题的井也遭受了液体负荷的困扰。安装速度管柱(VS)作为气孔反液化的主要手段。许多带有 VS 的井没有显示出进一步的石盐沉积。

Velocity String Revives Production of Deep Gas Wells With Halite Deposition

This paper describes treatment of deep gas wells experiencing halite deposition by installation of a velocity string that creates synergy between gas-well deliquefication and halite management.

The complete paper describes a scenario in which, following the reduction of system pressure through depletion compression, more than 150 deep gas wells began experiencing halite deposition. Many of the wells with this issue were also suffering from liquid loading. Velocity strings (VS) were installed as the primary means of gas‑well deliquefication. Many of these wells with VS showed no further halite deposition.
