ABSTRACT:
A method of providing a conductor pipe to an opening portion of a well such as an oil well, gas well, geothermal power well or the like. A bore is formed in the ground with a casing tube and an auger screw, inserted into the casing tube, to a predetermined depth, after which the auger screw is withdrawn from the casing tube. Then, the conductor pipe is inserted and concentrically positioned in the casing tube, placed in the bore, to form an annular space between them, to which space a solidifiable filler is supplied from the bottom portion of the space to the upper portion thereof. The casing tube is thereafter withdrawn from the bore and then the filler is solidified to thereby fix the conductor pipe to the opening portion of the well.
