摘　　要：本文介绍了大庆油田侧钻水平井机械堵水的工艺技术，并从工艺的可行性、安全性、经济合理性进行论证。为确保堵水管柱安全起下，对插入密封段的合理长度进行了理论计算，用计算机程序模拟计算了管柱起下时的受力情况，并给出了计算结果，为侧钻水平井堵水工艺的实施提供了科学的理论依据。The paper introduces the mechanical water plugging technologies in a laterally drilled horizontal well of Daqing Oilfield and demonstrates the feasibility,safety and economic rationality of the technologies.In order to make sure of plugging pipe string run safely,the reasonable length of inserting into the sealed interval is calculated in theory and furthermore the stretched and compressed conditions of the running pipe string are also simulated and calculated by computer program.The above calculated results provide scientific basis in theory for practising water plugging technologies in a laterally drilled horizontal well.
