APPLICATION OF FISHING TOOLS IN LIQUIDATION OF CAPILLARY TUBES BREAKAGE IN OIL WELLS

Annotation. This article discusses one of the most common accidents that occur during mechanized oil production – these are capillary tube breaks, which require significant time and material costs to eliminate. Therefore, the solution to this issue requires the modernization of equipment during the relevant operational fishing operations. Currently, they are the most complex and time-consuming types of emergency work performed during major well repairs. To solve the problem, it is proposed to use an upgraded fishing tool, the use of which will significantly reduce the cost of repairing wells, as well as work related to the replacement of logging cables, electrical cables, ropes, wires, and capillary tubes. The reliability of using this tool is proved by the obtained operational characteristics of wells.

Keywords: mechanized oil production, capillary supply systems, capillary tube breaks, borehole, fishing tool.
