摘要： 针对苏里格气田低压、低产气井的产水气状况及特点，开展了泡沫排水采气工艺技术研究。通过室内实验，对4种泡沫排水剂在90 ℃条件下进行了携液力、动态携水和配伍性试验，结果表明，0.5%的UT-11C泡沫排水剂泡沫稳定性好，动态携液能力强，单井产气量较试验前有所增加，并具有良好的缓蚀性能。这项工艺为苏里格气田泡沫排水采气的推广、应用打下坚实基础。

Abstract: In view of producing water?bearing gas from gas wells with low pressure, low productivity in Sulige gas field, the foam drainage gas recovery technology is studied. The experiments of four types of foaming agents in fluid?carrying capacity, dynamic carrying water and compatibility at 90℃ are tested. The results show that the foaming agent of 0.5% UT?11C is of good stability, good dynamic liquid carrying capacity and good corrosion inhibition performance. And the gas production of well has more increased than before for its better liquid carrying effect, bringing about the expected target for foam?drainage enhancing gas recovery
