摘要： 针对我国油田水含量日益增高的现状,泡沫具有良好的封堵性能和液流改向作用,拥有广阔的应用前景。主要对泡沫的封堵特性和液流改向作用进行了研究,分别考察了不同条件下泡沫的封堵特性,并考察了泡沫的液流改向作用及提高采收率效果。结果表明,泡沫具备良好的封堵特性,可在适宜条件下实现有效封堵。回压越高、气液体积比越大、岩心渗透率越大、泡沫注入速度越低,泡沫的阻力系数和残余阻力系数越大,泡沫的封堵越强。对于渗透率级差为5.56的非均质油藏,泡沫具备液流改向作用,可以对高渗层选择性封堵,使后续注入水进入低渗层驱出残余油,泡沫驱提高采收率幅度达28%。

Abstract: In view of the increasing water content in China's oil fields, foam has good pugging performance and flow redirection effect, and has broad application prospects. In this paper, the sealing characteristics of bubble redirection effect was studied, the fluid flow was investigated under the condition of different seal characteristics of foam, and effect of flow redirection and enhancing oil recovery was examined. The results show that the foam has good plugging performance, and can be effectively blocked under suitable conditions. The higher the back pressure, gas liquid ratio and core permeability are, the lower the injection speed is, the bigger the resistance factor and residual resistance factor of the foam are, the greater the plugging is. For non-homogeneous reservoirs with a permeability differential of 5.56, foam has effect of flow redirection and can plug the high permeability layer in core selectively. The subsequent injection of water into the low permeability layer will drive out the residual oil, and the bubble drive will increase the recovery rate by 28%.
