METHOD FOR MANAGING MINERALIZATION OF SUPPLY WATER WHEN COMMISSIONING A PRESSURE WELL

摘要

The application describes a complex system, including a demineralization unit, comprising a reverse osmosis unit (RO) for generating a mixed stream of OO permeate and a nanofiltration unit (NF) for generating a mixed stream of NF permeate; mixing system; a control unit and an injection system for an injection well drilled into the oil layer of the reservoir; moreover, the mixing system is designed to mix the mixed flow of OO-permeate and the mixed flow of NF-permeate, to obtain a mixed flow of injected water, the control unit provides a dynamic change in the operation of the mixing system to control the amount of at least one of the mixed flows of OO-permeate and NF-permeate , to change the composition of the mixed flow of injected water compared with the initial composition, to obtain the target composition.
