针对目前液体消泡剂使用的局限性，川西气田引进了XXP‐1固体消泡剂，在含泡沫液天然气进入分离器之前消除其携带的泡沫。在X5、XC6和XY H F‐2井进行了现场试验。试验结果表明， XXP‐1固体消泡剂对X5、XC6和XY HF‐2气井水样具有较好的破泡、抑泡能力，平均破泡时间小于10 s ，平均抑泡时间大于6 min。加注XXP‐1固体消泡剂后，污水罐泡沫高度明显下降，站场月污水拉运量大大提高，天然气出站压力降低，接近管网压力。XXP‐1固体消泡剂能有效消除携液天然气中的泡沫，提高分离器气液分离效率。

Aiming at the application restriction of liquid defoaming agent ,XXP‐1 solid defoaming agent was introduced and field tests were conducted in X5 ,XC6 and XYHF‐2 gas wells of the western Sichuan gas field .T he results indicated that XXP‐1 solid defoamer has good capacity of breaking bub‐bles and inhibiting foam generation ,the defoaming time of XXP‐1 solid defoaming agent was less than 10 s and the inhibiting time was more than 6 min .The height of foam in sewage tank substantially re‐duced ,monthly sewage pull capacity of upstream well station was greatly increased ,and the gas out‐let pressure dropped and approached to the pressure of pipe network after injecting XXP‐1 solid de‐foamer .XXP‐1 solid defoaming agent could efficiently eliminate the bubble and improve the gas‐liquid separation efficiency .
