二元泡沫流动性能影响因素研究
摘要
Abstract
The foam effect on improving the core sweep efficiency and reducing permeability are investigated by foam flooding in porous media experiments. The influence of a-olefin sulfonate(AOS), hydrolyzed polyacry-lamide (HPAM) concentration, gas liquid ratio, core permeability, and injection methods on foam flooding property are explored. The experiment results show that foam flooding resistance coefficient and residual resistance coefficient increase with the increasing concentration of AOS and HPAM. The foam flooding resistance coefficient and residual resistance coefficient in the non-oil rock heart are more than three times of those in the oil-bearing rock. Under the condition that AOS and HPAM concentration are greater than a certain value, foam flooding resistance coefficient and residual resistance coefficient are stabilized. Appropriate increasing ratio of gas-liquid can improve foam flooding control ability, but too much ratio of gas-liquid will cause gas channeling. The same foam system does not improve flooding control ability of all different permeability cores. Advanced foam injection leads to the best mobility control than other ways. The mobility control of the alternating injection of liquid and gas foam decrease with the increase of alternating slug.关键词
