More Information
Summary:The invention discloses a modified oilfield acid regulation integrated technique and aims to provide an oilfield deep profile controlling and flooding technique which allows continuous construction, fewer moving string steps, simple process, low risk and low cost. The acid regulation integrated technique is continuously carried out for construction according to a sequence of temporary plugging process, acid regulation process and profile regulation process. The technique also comprises a cleaner injection process. The technique is suitable for water injection wells, having great inter-reservoir differences, non-uniform inter-reservoir suction profiles, low water injection pressure with high water injection quantity, and severe injected water rush in high permeable layers.
