摘　　要：介绍了机械找堵水一体化管柱的结构、工作原理、技术特点及在大港油田的应用情况。该项技术主要是用自验封封隔器将各产层分隔开,对应各产层位置下入一个找堵水开关,通过地面液压控制来调整各产层开关的工作状态,对各目的层进行生产;通过地层正常生产时产出液的情况来判断各层含水情况,确定高含水层,开关并能重复多次换层生产,达到不动管柱完成找堵水的目的。Introduced integration string structure,operating principle,technique feature and application in Dagang Oilfield of machine water plugging.This technology uses self-seal-check packer to separate every layer and put a water plugging switch,control switch working state with surface hydraulic.Diagnose water cut of every layer from produced fluid,and find high water cut layer.Switch can be reused and change layer to producing,and can realize water plugging but not need to remove string.
