Integrated Intelligent Boosting Water Injection Device is a boosting equipment used for boosting at the terminal of oilfield water injection pipelines or boosting at water injection wells. This device consists of boosting water injection pumps, high-pressure basket filters, intelligent precision injectors, electric multi-stage regulating valves, process pipelines, and supporting valves. It integrates functions such as filtration, boosting, metering, and automatic control. It is suitable for water injection projects in low-permeability oilfields with high-pressure under-injected wells and locally under-injected small blocks. The skid-mounted device can be transported to the well site and connected to the water distribution valve assembly for immediate use, replacing conventional boosting water injection stations in oilfields. This approach minimizes construction time, investment costs, and maintenance expenses to the greatest extent possible.
