采用常规方法对作业井泵注作业,成本大、风险高,且泵注效果不好。通过连续油管配备相应工具,可实现不起出原井管柱、不停泵的连续进行泵注,另可配备其他工具,实现钻磨、酸化、解堵等多种作业,取得了良好的经济效益和社会效益。 Using conventional methods to pump work wells, the cost is high, the risk is high, and the pumping effect is not good. By coiled tubing equipped with the appropriate tools, can not achieve the original well string, continuous pump continuous pump injection, the other can be equipped with other tools to achieve drilling, acidification, plugging and other operations, and achieved good economic returns And social benefits.
