Development of tools for cleaning well downhole from metallic items (in the order of discussion)
R.A. HasanovThe paper considers the process and design of well equipment for cleaning well from junk. Possibility of catching and removing junk from the well via friction welding that enables simplification the structure, as well as decrease overhauls labor content using fishing tools is confirmed and experimentally proved. Satisfactory quality of welding joint for fishing junk (by typical size and material) can be obtained in certain diapasons, rotation rate and value of axial load in cocking, as well as realization time of connection process with emergency tool.
