The article describes tests on the core to select the optimal drilling fluid formulation when drilling wells of the Parfenov horizon. The purpose of the research work is to study the effect of drilling fluid filtrates on rock permeability. The study was carried out in four stages. At the first stage, the initial permeability was measured. At the second stage, modeling of drilling fluid infiltration in the formation was performed. At the third stage, the drilling fluid was subjected to aging treatment was. At the fourth stage was devoted to the inflow stimulation, cleaning of the near-wellbore zone and measuring of the restored permeability. Summary results of testing the properties of solutions for the Parfenov horizon are presented.
