During drilling process,drilling fishing cup is applled mainly for
fishing of shivers and fallen objects such as carbide tooth,drill
bit and bearing which can not be carried out of hole by
conventional fluid circulartion,etc it possesses important
functions to keep hole toe cleaning ,increase bit service
life,reduce and prevent drill bit from unexpeeted damage.
Structure
Due to the fact that the O.D of external bowl of fishing cup is
bigger and a smaller circular space is available between extemal
bowl of fishig cup and well hole; the mandrel diameter at cup mouth
is larger so that it has a bigger annular space, therefore, the
fluid at the cup mouth form a swirls and suddenly fall down so as
to reduce the carrying capacity.By this way,some heavy objects will
drop in cup and be fished out so that the purpose of cleaning of
hole toe is carried out.
