发明名称 Method for reducing the injection pressure of a polymer solution in an oil well without shear degradation
摘要 The method involves inserting a main displacement pump between an injection pump and an oil well, where the displacement pump is a gear pump. Speed of the displacement pump is controlled using Telma(RTM: electric brake), where the displacement pump is reversible. The brake is connected to an engine shaft, where speed of the displacement pump is controlled by a valve that is located in downstream of the displacement pump. Closing and opening processes of the displacement pump are managed according to injection pressure determined for the well.
