Research And Application In Gas Production With Foam Draining Water

Along with the gas field development further, the production and pressure of gas well gradually reduced, for the gas well with water production, it would be get more and more water in wellbore, which is obstacles that SongYuan gas extraction plant can Normal, long-term and stable production. This paper analyzed and studied using foam drainage technology to solve gas well bottom-hole effusion and gas well production problems.Through comparison of various drainage gas extraction process, first selection technology of drainage gas production, Recovery from foam drainage technology mechanism analysis, in the basis of correct understanding to gas reservoir geological conditions ,Carrying out experiments in indoor. Through the experiment we found that UT - 4, UT - 6, UT - 11D is the right elixir. Application in five gas Wells to find the injection pattern, the period and the dosage of the gas well. After gas well drainage, monitor records and analysis the production data. Optimization of process arameters and get better effect.This paper's analyzed and research has very big effect on water production Wells with liquid and continuous discharge bottom-hole effusion, also has the extremely vital significance on the long-term development of gas field.
