Systems of drilling solutions for the disclosure of productive oil seams that are used in the deposits of Ukraine are analyzed. The attention is paid to the factors influencing the deterioration of the permeability of the productive strata. The model is improved and the criteria of optimality of the choice of drilling solution formulations for qualitative disclosure of productive oil reservoirs are substantiated. The two-step procedure for choosing optimal drilling fluid formulations is proposed. In the first stage, the basic formulation of drilling solutions is chosen from the solution of the auxiliary quasi-equivalence problem, and in the second stage, based on the basic formulation, the optimal composition of the surfactant is chosen from the condition of minimizing the interfacial tension at the interface of the phases of the drilling mud oil filtrate. The influence of the most common surfactant drilling on the coefficient of interphase tension and the critical concentrations of micelles formation has been studied. Based on the criterion of minimum interphase tension, the optimal formulations of humate-biopolymer drilling mud (HBBD) and biopolymer (BBB) ??drilling fluids for the disclosure of productive strata have been substantiated. The rheological properties were studied and the structure of the emulsions of filtrate biopolymer solutions with oil from the Milkovsk and Bugrutov deposits was studied. The optimal composition of surfactant was selected and an industrial test of Bio-polymer biopolymer drilling solution was conducted on one of the wells of Semerenkovsky deposit.
