油井出水是目前油田开发过程中普遍存在的一个问题,特别是为了保持地层压力,采用早期注水开发的油田,出水尤为严重。这不仅使地面脱水工作量越来越大,而且最后会导致原来经济效果好的生产井,变为无工业开采价值。因此,油井堵水是保持油田稳产、增产的一项技 Water outflow from oil well is a common problem in oilfield development at present. Especially in order to maintain formation pressure, it is very serious to use oilfield developed by early waterflooding. This not only makes the work on the ground dehydration more and more large, but also finally leads to the originally economically productive production wells, turning into non-industrial production value. Therefore, oil well water shut down is to maintain a stable oil production, increase production technology
