PROBLEM TO BE SOLVED: To provide a water treatment system capable of preparing, from seawater and accompanying water, injection water enabling oil drilling without abating the oil collecting efficiency while environmental protection is being taken into account.SOLUTION: The provided water treatment system is furnished with: a freshwater flow channel through which freshwater from a seawater desalinator 3 for obtaining freshwater by desalinating seawater is permeated; a treated water flow channel through which treated water from an oil-water separator 10 for obtaining treated water by removing the oil content included within accompanying water from an oil field is permeated; and an injection water preparation flow channel for preparing injection water to be injected into the oil field by merging the treated water permeated through the treated water flow channel and the freshwater permeated through the freshwater flow channel. 【課題】環境保全を考慮しつつ、採油効率を低下させることなく採油可能な圧入水を、海水と随伴水とから調製可能な水処理システムを提供する。【解決手段】海水を淡水化して淡水を得る海水淡水化装置３からの淡水が通流される淡水流路と、油田からの随伴水に含まれる油分を除去して処理水を得る油水分離装置１０からの処理水が通流される処理水流路と、前記処理水流路を通流する処理水と、前記淡水流路を通流する淡水とを合流させて、油田に圧入する圧入水を調製する圧入水調製流路とを具備することを特徴とする、水処理システム。【選択図】図１
