摘　　要：二连油田针对“双高注水”产生的一系列矛盾有效开展了以“提液降压”为主的油田综合治理工作。在解堵工艺上初步形成了以有机复合解堵为主多种工艺方法并存的基本框架。通过对堵塞机理的深入研究及解堵工艺的适应性分析 ,加大了经济适用型解堵工艺的应用力度 ,取得了很好的增油效果。An effective comprehensively broken down works have been implemented aimed to increasing production and decreasing pressure to the contradiction caused by dual high water injection in Erlian oilfield.Based on it,a structure of taking organic composite to break down as the prime consideration and combining multiple technologies presence has been competed.By deep study to the plugging mechanism and analysis to the broken down adaptability,the application of economical type of technique has been strengthen and gained a good result of increasing oil production.
