FIELD: oil and gas industry.SUBSTANCE: invention relates to the oil and gas industry and can be used in the oil and gas wells drilling in swelling and dispersing clays. Drilling mud inhibitory properties determining method is in fact, that, based on the drilling results in the selected area, determining the amount of operating time when drilling with design solutions (V) and the operating time actual amount (V) during drilling with the test solution, determining the operating factor Kas ratio of the operating time actual amount Vduring drilling with the test solution to the certain amount of operating time during drilling with design solutions (V): K=V/V=(V-V)/V, where Vis solution on the surface total amount; Vis the solution on the surface required amount; by recorded in the generated reference database the operating time factors, estimating the test solution inhibitory properties as high at 0≤K1 and determining the accumulated during the well construction at particular field disposed solution amount.EFFECT: increase in the drilling efficiency.1 cl, 2 tbl
