Abstract
636,879. Drilling wells. JOANNESJAN, R. A., TAGUIEV, A. I., GOUSSMAN, M. T., and FISH, J. L. July 12, 1946, No. 20941. Drawings to Specification. [Class 85] In the directed drilling of deep wells there is angular displacement between the rigid end of a non-rotating drilling column and a toolrotating turbine. Preferably the column is formed by a string of piping, whilst the angular displacement may be effected by means of a bent thick-walled drilling tube, a bent tube or an eccentric setting device between the column and the turbine, or a deviating slide on the turbine.
