摘　　要：针对苏里格气田井内积液严重且存在高矿化度高温的实际开采情况,文章采用气流法考察了苏格里现役液体泡排剂、纳米泡排剂、固体泡排剂、十二烷基硫酸钠、α-烯基磺酸钠和脂肪醇聚氧乙烯醚六种不同泡排剂的起泡性能,对它们产生泡沫的稳定性、携液能力及表面张力进行了测试,得到结果:纳米泡排剂>α-烯基磺酸钠>液体泡排剂>十二烷基硫酸钠>脂肪醇聚氧乙烯醚>固体泡排剂。后续测试了地层矿化度和凝析油对泡沫性能的影响,最后根据综合结果得出,纳米泡排剂是最适宜苏里格气田使用的泡排剂。In view of the actual production situation of Sulige gas f ield with serious fluid accumulation and high salinity and high temperature,this paper uses the gas flow method to investigate the bubbliness properties of six different bubbliness discharge agents,namely liquid foaming agent,nanofoaming agent,solid foaming agent,sodium dodecyl sulfate,sodiumα-enyl sulfonate and fatty alcohol polyoxyethylene ether.Their foaming stability,liquid carrying capacity and surface tension were tested,and the results were as follows:nanobubble effluents>α-enyl sulfonate>liquid foaming agent>Sodium dodecyl sulfate>fatty alcohol polyoxyethylene ether>solid foam discharge agent.The influence of formation salinity and condensate oil on foam performance was tested.Finally,according to the comprehensive results,nano-bubble discharge agent is the most suitable foam discharge agent for Sulige gas f ield.
