针对油水井检泵、压裂、换封等作业过程中,探冲砂和通井是都要下一趟管柱、起一趟管柱,下管柱和上提管柱占去这两个工序的大部分时间的问题,冲砂通井器的研发可以使探冲砂和通井工作通过下一趟管柱来一次完成,节约了作业时间,降低了工作量,提高了作业效率。 For oil and water well inspection pump, fracturing, changing the seal and other operations in the process of exploration sand and through wells are the next trip to the next column, from a trip column, the next column and the lifting of the possession of these two columns Most of the time the process of the problem, the research and development of red sand through the well can make the exploration of sand and pass through the next pass to complete a column, saving time, reducing the workload and improve operational efficiency.
