A study of the reservoir characteristics of the Tournaisian formation in the Yablunivske oil and gas condensate filed shows that the pore structure of the reservoir in this area is complex and the pore permeability varies widely. Based on the reservoir logging response characteristics, core analysis data and logging curves GR, DT and normal resistivity curves, the reservoir mud content, porosity, permeability, bound water saturation and gas saturation parameters were calculated by statistical regression methods. The calculation accuracy of the established log interpretation models is high, which can meet the development needs of the oilfield and also lay the foundation for the subsequent study of the reservoir.
