At present, there is a general tendency to increase the depth of drilling wells for oil and gas. A significant number of wells, especially in areas with a strong sedimentary cover, are drilled to depths of 5-7 thousand m. Drilling wells to such depths is associated with increasing difficulties in their wiring due to the complexity of mining and geological conditions, which primarily include an increased frequency of meeting strata with abnormally high reservoir pressures.
