Research methods - analysis and generalization of experience in drilling wells in difficult conditions. The experience of well construction in sections with complicated conditions is described: quality systems of well construction, requirements for well constructions, drilling fluids, innovative technologies of deepening and well control. The technologies of drilling for production columns of wells 72- and 75-Semirenkivska are analyzed: drilling muds, geometrical parameters of wells, bottom drill string assembly, complications. The causes of complications are specified. The indicators of the balance of the calendar time of drilling are given. The strategy of controlling the stability of well walls is substantiated. A set of measures for the selection of the composition and properties of drilling mud for drilling complex intervals under the production string is proposed. The efficiency of the possible application of the WITER II invert-emulsion system for drilling under the production string was evaluated. The expediency of using drilling technology with simultaneous expansion of the wellbore, as well as an alternative well design.
