摘　　要：泡沫在三次采油中的研究已有30多年的历史，并被应用于现场，取得了一定的成效。针对高温高矿化度油藏的特征，在80℃下，分别在不同类型及其浓度的盐溶液中，对几种稳泡剂的抗盐性进行了评价，筛选出了抗盐性能最佳的稳泡剂HXYP。0．2％稳泡剂HXYP＋0．2％起泡剂HXY-1泡沫体系在80℃下抗NaCl、CaCl2以及NaCl和CaCl2混合盐的浓度分别达到16×10^4mg／L、4×10^3mg／L、14×10^4mg／L。Foam flooding has been studied for more than 30 years in TOR (tertiary oil recovery).Being widely used in the field,it has seen good effect.Aiming at the character- istics of the high salt and temperature-resistant oil reser- voir,the salt resistance of several kinds of foam stabilizer has been evaluated respectively in different salt types,un- der the temperature of 80℃.The selected foam stabilizer HXYP has the optimal salt-resistant capability.Com- posing of 0.2% foam stabilizer HXYP and 0.2% foaming agent HXY-1,the foaming system has excellent charac- teristics when the concentration of sodium chloride/calci um chloride or salinity is 16×104mg/L,4×103mg/L, 14.18×104mg/L respectively under the same temperature of 80℃.
