为了评述原油对水相泡沫稳定性的影响机理,分别介绍了原油在水相泡沫中的存在状态,原油对泡沫的稳定或破坏机理.原油对泡沫的稳定性有着显著影响,稳泡或消泡也极大程度上决定了石油与天然气开采作业中,诸如泡沫驱油、泡沫堵水、堵气、泡沫排液、泡沫压裂等作业效率.重点阐述了假乳液膜对泡沫稳定性的影响机理,总结出原油在水相泡沫体系中以溶解油或乳化油两种状态存在.原油溶解于水相胶束中(溶解油)可降低泡沫的稳定性.大多原油在水相泡沫中以乳化油滴形式存在,油滴与气泡之间被假乳液膜隔开,假乳液膜决定了泡沫体系的稳定性.假乳液膜稳定性好能促进三相泡沫的稳定性;而假乳液膜稳定性差就加剧了三相泡沫地破裂.通过评述指出了原油与水相泡沫相互作用研究领域今后的研究方向.

In order to study the mechanism for the effect of crude oil on the stability of aqueous foam,behavior of crude oil in aqueous foam and the phenomena of the effect of crude oil on the stabilizing or destabilizing the aqueous foam were reviewed.The crude oil exerts a significant effect on stability of aqueous foam,since it could stabilize or destabilize the aqueous foam,which decides the efficiency of petroleum and natural gas enhanced recovery operations to a very big extent,such as foam flooding,gas (water)-blocking,foam fracturing and foam deliquification.The effect of pseudoemulsion film on the stability of foam system was focused.In the aqueous foam system,crude oil exists as solubilized state or emulsified state.In case the crude oil is solublized in micelles,the foam stability would be depressed.In majority cases,the crude oil is existed as emulsified droplets state while the oil droplets are separated with the gas bubbles by pseudoemulsion film.The pseudoemulsion film decides the stability of the foam system.Pseudoemulsion film with good stability will enhance the stability of the three phase foam system;while on the contrary,pseudoemulsion film with lower stability would cause the rapture of three phase foam.Outlook of the research work in this field was prospected.
