Description

Technical field: [0001] The invention relates to an anti-rod column breakage device for pumping wells and a use method thereof. Background technique: [0002] The diameter of the rod column of the pumping well is not large, and sometimes it will break during use. Once it breaks, it will fall into the sleeve. Since the rod column is smooth, it is very difficult to take it out. If you want to take it out, you must disassemble it. Whole pumping unit, not only waste time like this, but also waste manpower, and have a strong impact on the normal use of pumping unit. Invention content: [0003] The object of the present invention is to provide a rod string breakage prevention device for pumping wells that can smoothly take out the broken rod string and has a good use effect and a use method. [0004] Above-mentioned purpose realizes by following technical scheme: [0005] An anti-rod column breaking device for pumping wells, its composition includes: an overcoat, a combined po...
