在四川石油地质勘探开发研究院的指导下,近三年多来,川南矿区先后在39口四种类型井上开展了泡沫排水采气试验,在22口井上获得成功,累计产气量4649万米~3,纯增产总价值达367.9万元,并在试验中较好地解决了消泡和注入设备问题。一、化学泡沫排水对不同类型气水井的适应能 Under the guidance of Sichuan Petroleum Geological Exploration and Development Research Institute, in the past three years and more, the coal mining area in southern Sichuan has carried out a foam drainage and gas recovery test on 39 types of four wells and succeeded in 22 wells with a total gas production of 46.49 million meters ~ 3, the total net production value of 3679000 yuan, and in the experiment to better solve the problem of defoaming and injection equipment. First, the chemical foam drainage adapts to different types of gas wells
