摘　　要：用阴离子、非离子和氟化表面活性剂、三聚磷酸钠、水玻璃及胜利金家油田注入水配制的起泡液，起泡能力强，形成的泡沫稳定性好，可通过乳化作用降低金家粘性原油的表观粘度。在人工填砂模型上，该起泡液与８倍体积的氮气形成的泡沫驱出了水驱残余油１６．４％，提高采收率６．９８％。A foaming solution is prepared from an anionic, a nonionic and a fluorinated surfactants (as foamers), sodium triphosphate and water glass in injection water for Jinjia Oil Fields of Shengli. The foaming capacity of this solution is high and the life of foam created is long. This solution can readily emulsify Jinjia's crude and thus reduce its viscosity dramatically. In a foam flooding experiment on a artificial core, 16.4% residual oil of water flood is recovered, that is, oil recovery enhancement is 6.98%.
