Abstract
Abstract This disclosure relates to apparatus for drilling wells for oil, gas, water, etc., wherein the device for drilling is placed in a rigid cylindrical collar which is expanded and pressed in the walls of the well. The collar absorbs a reactive torque from drilling. In the upper part of the walls of the collar control devices are installed which send up the signals about outside collar pressure, temperature, etc., and thus indicate any complications in the process of drilling. The collar is coaxially joined at its upper end to a thin-walled, continuous tube which is formed from a coiled sheet by drawing the sheet through a rolling-up system of rollers. The tube is axially extended and retracted by a mechanism which has two or more systems of tube moving elements which are symmetrically disposed relatively to a longitudinal axis of the tube and engage the external surface of the pipe column with forces which are sufficient to create the necessary friction forces for moving the tube. As the tube is extended, it draws a continuous sheet through the rolling-up system of rollers. The sheet at the time of the rolling-up embraces communication such as the pipes for feeding liquid to remove earth or rock, the electrical cable, the auxiliary flexible pipe for feeding liquid to a hydraulic cylinder, etc. During retraction, the tube is drawn through the unrolling system of rollers, unrolling it into a sheet which is wound in a coil by the winding mechanism.
