摘要： 长庆油田储层属于典型的低渗透，需要注水进行开发，随着开发时间的延长，部分区块进入开发中后期，油井含水不断上升，给油井增产改造带来了很大困难。通过对长庆低渗透储层特征、开发现状、见水原因分析的基础上，通过室内研究，形成了注水井深部调剖、油井堵水、堵水压裂、裂缝深部暂堵酸化等中高含水油井增产技术。目前在现场应用６１口井，取得了较好的措施效果，为长庆油田低渗透储层中高含水油井提高单井量进行了有力探索。

Abstract: Reservoirs in Changqing oilfield typically belongs to those with low permeability, which entails water injection for the development. Along with the extension of development, some blocks have entered into the mid-late period of the development, with gradual increase of water-cut, which brings enormous difficulties for the stimulation of producers. On the basis of reservoir features of lower permeability, current status of development and reasons of water breakthrough in Changqing oilfield, comes up with technologies to improve production of single well with mid-high water-cut, such as profile adjustment in deep formation in injectors, water shutoff in oil producers, water shutoff and fracturing and temporary shutoff and acidizing in deep part of fractures. Currently, these technologies have been applied in 61 wells, with effective results obtained, which is a great breakthrough in increasing production of single well with mid-high water-cut in Changqing oilfield where reservoirs are featuring low permeability.
