摘　　要： 简要分析了埕岛油田先后采用的3种分层防砂分层注水工艺的特点。由于密闭注水分层防砂同心双管注水工艺和密闭注水分层防砂同心单管注水工艺不能满足海上注水要求,逐渐被淘汰。大通径分层防砂二次完井分层注水工艺成为目前海上注水主导工艺技术。同时介绍了以大通径分层防砂为主的二次完井的类型特点及应用情况。 First the characteristic of three different kinds of separate layer sand control and zoon water injection technologies one after another used in Chengdao oilfield are introduced. Because the first two technologies can＇t meet the need of water injection,they were gradually replaced. At present the large-diameter separate layer sand control and zoon water injection technology is dominant in Chengdao oilfield. At last the types of water injection on a base of large-diameter separate layer sand control technology are introduced.
