The inhibiting drilling muds and stability of clay rocks

Authors: A.A. Khubbatov, A.M. Gaydarov, A.D. Norov, M.M. Gaydarov (Gazprom VNIIGAZ LLC, RF, Moscow)

Key words: inhibition, drilling mud, clay rock, drilling, research, polymer.

The article considers inhibiting properties of drilling muds and stability of walls of wells. Traditionally used inhibiting drilling muds at well drilling in thicknesses of swelling clay rocks do not reduce operating time of excess mud volumes and do not provide stabilization well bore. For the first time, it is offered, the developed drilling muds stabilized cationic the polymers, not having analogs, one of which updating has successfully passed trade tests on well of No. 939 Astrakhan gas-condensate field.
