泡排剂性能评价实验研究

Experimental Research and Assessment on Foaming Agent Performance

起泡剂在井底条件下的发泡性能直接影响气井的排水效率,从而影响气井产能的恢复状况。文章从浊点、动态表面张力、泡沫高度及半衰期等方面对3种起泡剂的性能进行了评价,优选出了一种适合中原油田高温高矿化度的泡排剂。

The foaming performance of foaming agent under downhole conditions influences directly the drainage efficiency,thus influences the restoration of gas-well productivity.Three different foaming agents were evaluated in terms of cloud point,dynamic surface tension,foam height and half life.The foaming agent which is suitable for high-temperature and high-salinity gas wells in Zhongyuan Oilfield has been selected.
