Abstract
A roller drilling rig includes a mast, drive for drill-rod column feeding motion as hydro-cylinders connected to flexible cable con-rods of the type of polyspasts, and centralizers-stabilizers of cross vibrations of the drill-rod column. To exclude or to decrease substantially cross vibrations of the drill-rod column over the walls of the well, to exclude need of rodding the well with pulp, to decrease energy consumption for drilling and to decrease abrasive wear of the rods, the centralizers-stabilizers are arranged as elastic-damping buffers-holders installed normally with respect to the axis of the drill-rod column, at several sides round it in the lower section of the mast of the rig, connected with the devices for pressing those to the drill-rod column, and in contact with it through pair rollers the axes of which are placed at angle to the axis of the drill-rod column. Each pair of rollers is placed at distance of the width of buffers one with respect to another along the axis of the drill-rod column.
