| Abstract: | In order to solve the problem of sand plugging in the process of fracturing flowback in deep coal measure gas wells,through full investigation and field analysis,the method of changing the conventional workover operation mode and using coiled tubing to solve the problem of sand plugging is proposed.This method has been practiced in the production field of Shixi coal measure gas wells,and the sand plugging caused in the fracturing process of the SX-012 well has been successfully removed,and good gas production effect has been achieved,which can be widely used to solve the problem of sand blocking in the process of deep gas well development. |
