The authors of the article present the results of studying the influence of some inhibitory additives on clay rocks stability during drilling. A certified method for measuring the steady state period under uniaxial compression and relative vertical deformation during artificial cores swelling in a liquid medium FR.1.28.2022.41903 was used. The studies were carried out using artificial cores manufactured by pressing from non-treated bentonite clay powder of PBN grade. This material is representative of clay deposits upper layers of oil and gas fields, characterized by high activity and ion-exchange capacity. Comparative data on the swelling and creep parameters for samples being in contact with distilled water, solutions of NaCl and KCl salts, and commercial samples of inhibitors (sulfonated asphalt, PHPAA, polyglycols, etc.) were obtained. It was revealed that solutions of KCl, polyglycol, PHPAA and sulphonated asphalt demonstrated better inhibiting efficiency, significantly reducing both swelling deformation and slowing down the destruction of samples under load.
