| 摘 要： | 根据大庆榆树油田注水井地层，井筒及其配套系统结垢原因，研制了清垢剂（地层解堵剂）YQG和防垢剂YFG；针对该油田储层特点开发了运用暂堵转向技术，能控制处理强度的注水井清垢解堵工艺，应用该工艺和清垢剂YQG在8口注水井进行清垢解堵试验，获得了良好的增注效果；在13口注水井进行连续注入防垢剂YFG的长期（1年）防垢试验中，注入压力上升幅度和视吸水指数下降幅度均显著减小。 |

| Abstract: | Scales of mainly inorganic nature occured in the pip elines, wellbores and near borehole zones of water injection wells at Yushulin O il Field in Daqing. To solve these problems a scale remover, YQG(an organic acid izing fluid), and a phosphonate scale inhibitor, YFG, are prepared and proper te chnologies of applying these chemical agents are developed. The long term field tests of treating near borehole zones of 8 wells by using YQG and a particulated temporarily polugging agent and of continuously treating injection water for 13 wells by using YFG are performed successfully. |
