Part 11 Tertiary Recovery Equipment

1. Polymer Injection Equipment

        Polymer injection equipment is mainly used to enhance the recovery of oilfield by dissolving polymer powder and water at certain proportion and injecting the polymer solution into formation to increase oil production. All the key parts of the equipment have optimized design, which can effectively control the rate of shear degradation. The equipment can be either skid-mounted or fixed station type and is mainly consisted of dissolving unit, curing unit, feeding unit, injection unit and automatic control system.
       ● Features
