摘　　要：连续油管冲洗解卡堵技术主要用于高凝油或稠油凝结卡堵,气井中的水合物冰堵、砂卡或砂埋,电泵采油井或自喷井严重结蜡及其它复杂油水井的处理,这类井既无法建立循环又不能起出管柱,用常规方法处理施工难度大,工期长,费用高,易发生卡管事故,而且效果也不理想。用连续油管冲洗则显示出极大的优越性,经济效益显著。The technique of breaking down or releasing stuck by flushing with coiled tubing is mainly used in the cases of high pour-point oil coagulation or heavy oil coagulation in oil wells,hydrate ice plugging,sand plugging in gas wells,serious paraffin deposit in oil/gas wells or other complex cases,when circulation can't be done or pipe string can't be pull up and so conventional methods are very difficult to be used.The technique has been proved having great advantages and benefits.
