What aspects should be paid attention to in the drilling process of water well drilling rig?
After the drill bit is drilled into the structure from the drilling
platform, the central drilling tool shall be replaced in time.
First, you need to clean the bottom of the hole, and then blow off
the residue at the bottom of the hole. When the lifting force is
sufficient to lift the drill bit, slow lifting force is good.
During the drilling process, the drill bit was summarized, the
follow-up situation of the casing was noted, the specific situation
of the borehole was determined within a certain time, the borehole
was kept clean in time, and the drill bit was put into the drill.
You need training. During this process, forced lifting is
prohibited.
Sometimes, there will be a lot of residual rock slag at the bottom
of the hole of the water well drilling rig, and the rotary part of
the eccentric drill bit will be stuck by the rock slag, which will
affect its gathering and production. At this time, it is necessary
to convey compressed air to clean the hole again, and make the DTH
hammer work for a short time, and then carry out the lifting
operation of the central drilling tool again.
