集中注水工艺将注水站建在联合站或转油站内，站外系统均为高压管网，源水经过配水阀组调节分配后输至注水井口、集中注水工艺中，注水泵排量大，数量少并集中建设，所带井数多（一般在２０ 口以上）。分散注水工艺将水质处理部分建在转油站内，转油站至注配站之间采用低压供水，注配站则采用高压注水管线将源水输至注水井口。分散注水工艺中，注水泵排量小，数量多，分散建设。开发面积较大，注水井公布集中的新建产能区块，应采用集中注水工艺，零散井及扩边井工程则应用分散注水工艺。
Concentrated water injection process will be built at the joint station or transfer station filling stations outside the station system are high pressure pipe network, the source water through the water distribution valve group assigned to the injection wellhead after adjustment, focus on water injection process, injection pump displacement, the number of Less and focus on construction, with the number of well (usually more than 20). Dispersed water injection process will be part of the water quality built in the conversion station, transfer stations to the injection station using low pressure water supply, injection stations are used to high-pressure water injection pipeline to the source of water injection wellhead. Dispersed water injection process, injection pump displacement is small, the number of decentralized construction. Development of large area, well announced focus on the new production capacity of the block should be used to focus on water injection technology, scattered wells and expansion wells project is the application of distributed water injection process.
