二元超低界面张力泡沫体系渗流特性
FILTRATIONAL CHARACTERISTICS OF THE BINARY FOAM SYSTEM WITH ULTRA-LOW INTERFACIAL TENSION
摘要
Abstract
In order to completely understand and study the flow mechanism of binary foam system in porous media, the filtrational characteristics of a new-type polymer/surfactant binary foam system are figured out in quartz-sand filled tube model with 20 cm length and 2. 0 cm diameter. The results show that the changes of both foam uniformity and its time coming out of the core are not obvious under the different shear conditions and moreover in the state of flowing, the system possesses much better stability and foam shut-off capacity; at the same time, the pressure differential of the foam flooding increases with the rise of gas-liquid ratio, but the degree is not great; under the conditions of the same formulation, drag coefficient and residual resistance coefficient rise with the increase of the above ratio. The results confirm that the binary system has good capacities of both injection and close-off.关键词
