| Abstract: | On the basis of the principle of diverting and profile control, it's technology and research orientation of diverting agent are analyzed. A kind of formula of diverting agent is developed for profile control in water injection well through laboratory experiments of studying blocking ratio, pressure?tight strength, temporary blocking time and grain size etc of a kind of particle type water?soluble diverting agent. Field application shows that the technology is successful with obvious improvement on profile, and oil production response in oil well is better than that by regular profile control. |
