More Information
Summary:Provided is a water treatment system with which it is possible for injection water suitable for drilling to be prepared from seawater and produced water, without decreasing drilling efficiency, and with consideration to environmental protection. To achieve this, the system is equipped with: a fresh water flow passage for conducting fresh water from a desalination apparatus which desalinates seawater to obtain fresh water; a treated water flow passage for conducting treated water from a water/oil separation apparatus which removes the oil component contained in the produced water from an oilfield, to obtain treated water; and an injection water preparation flow passage in which the flows of treated water conducted through the treated water flow passage and the fresh water conducted through the fresh water flow passage converge, and injection water for injection into the oilfield is prepared.
