RACK MODULE FOR CASING PIPES Russian patent published in 2020 - IPC E21B19/14 

FIELD: drilling of wells.

SUBSTANCE: group of inventions relates to rack modules for casing pipes. Rack module for casing pipes includes: frame for casing pipes forming multiple rows; plurality of levers, connected with possibility of rotation with frame and made with possibility of rotation between first position of levers and second position of levers; plurality of shock absorbers, connected with possibility of rotation with frame and made with possibility of rotation between the first position of shock absorbers and the second position of shock-absorbers. Levers pass in rows in the first position of levers. Levers pass above the casing for casing in the second position of levers. Shock absorbers pass above frame for casing pipes in the first position of shock-absorbers. Shock absorbers pass in rows in the second position of shock-absorbers.

EFFECT: technical result consists in position control of lower end of casing pipes candles in such a way, which provides accuracy and protection of threads of casing pipes.
