捞砂工艺是适用于低压油水井清砂的一种工艺技术，但在捞油作业过程中往往遇到需要先捞砂的特殊情况，因此研究出新型捞油及捞砂悬绳器将捞砂工艺与捞油工艺融合为一套新工艺技术，用一套工艺设备即可完成捞油、捞砂任务。该技术具有施工周期短、易于操作、节省成本、减少地层污染等诸多优点，大大的提高了作业效率。%Tailing technology is suitable for low pressure oil-water well sand cleaning. The special situation that sand tailing needs to be done first in oil tailing process can happen very often. So a new type oil and sand tailing beam hanger is developed which combines the oil tailing technology and sand tailing technology. The single process can accomplish oil and sand tailing. It has advantages including short construction time, easy operation, low cost, less stratum pollution and so on, greatly improving the working efficiency.
