WATER TREATMENT SYSTEM

摘要

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.

1. A water treatment system comprising:
a fresh water flow path through which fresh water flows from a seawater desalination device for obtaining the fresh water by desalination of seawater; a treated water flow path through which treated water flows from an oil-water separator for obtaining the treated water by removing oil contained in produced water from an oilfield; and an injection water production flow path for preparing injection water to be injected to the oilfield by merging the fresh water flowing through the fresh water flow path with the treated water flowing through the treated water flow path.
