摘　　要：辽河油田已进入开发中后期,为进一步提高开发效果,水平井已成为老区块重要开采方式之一。目前共有水平井1300口,尤其是近几年随着开发的不断深入,油藏边底水活跃锥进速度较快,部分井产水量较大,有的井几乎全部产水,如何找到出水井段并进行封堵已成为难题。辽河油田钻采院通过技术攻关,研制成功水平井找堵水技术,通过现场45井次的应用,堵水增油效果显著。Liaohe Oilfield has entered the middle and late stage of development. There are 1300 horizontal wells in Liaohe Oilfield,which have played more important role in improving the development effect in old liberated area. However,especially in recent years with the development of reservoirs,the rapid active coning speed in edge and bottom water of the reservoir has led to more water produced in some wells,or most are water in some wells. It is difficult to find out water in wells and implement plugging. Horizontal well water detection and plugging has been successfully developed by the Drilling and Production Technology Research Institute of Liaohe Oilfield. The application in 45 wells has proved the effect of water plugging and the output of the wells has been improved significantly.
