摘　　要：介绍了化学堵水工艺在彩南油田的运用情况,根据彩南油田2口高含水水平井CHW04和CHW16井的情况,在分析了2口水平井出水原因的基础上,室内研制了化学暂堵剂和高强度堵剂,并研究出了施工工艺,采用研制的堵剂和工艺对CHW04和CHW16水平井各3次现场堵水施工后,取得了很好的增油降水效果,为水平井堵水在新疆油田的运用取得了一定的经验。This paper describes the use of chemical water shutoff at Cainan Oilfield.Based on the production and the analysis of water,of the two horizontal wells CHW04 and CHW16 with high water cut,the writes have invented chemical temporary blocking gel and high - intensitywater plugging agent,and also developed a construction technique.With the use of the developed blocking agent and technological,Every three times water shut - off on the two horizontal wells were made.After water shut - off construction,the two horizontal wells achieved very good effect of increasing oil precipitation.Successful horizontal wells in water shutoff provides a certain amount of experience for horizontal wells in Xinjiang Oilfield.
