长庆气田大部分气井主力气层为不含边、底水的马五１储气层，但目前发现，由于马五含有滞溜水，部分气井有大量的地层水产出。即使气井不产地层水，也会由于井底、井口状态参数的变化而产凝析水。为了防止地层水及凝析水在井底聚积，增大井底回压，降低气井产量，确定气井...
Most gas wells in Changqing gas field are mainly gas reservoirs without side and bottom water. However, it has been found that due to the presence of stagnant water in Mawu, some gas wells have a large amount of water produced by formation. Even if the gas well does not produce formation water, condensate water will also be produced due to the change of the well bottom and wellhead state parameters. In order to prevent the accumulation of formation water and condensate water at the bottom of the well, increase bottom hole back pressure, reduce gas well output, and determine gas well ...
