technical field

The invention belongs to the technical field of oil drilling equipment, in particular to an automatic vertical drilling tool stable platform function debugging experimental device.

Background technique

In oil drilling, a prominent problem that is often encountered is how to prevent the well deviation in the vertical well section, that is, to realize vertical drilling. The well deviation control of domestic vertical wells mainly adopts the pendulum combination drilling tool.
