    摘要: A method and apparatus for transmitting light through a light absorbing medium in which a light transmissive fluid column or channel contiguous with the light absorbing medium is formed in the light absorbing medium. The light is introduced into a light inlet end of the column of light transmissive fluid, whereby the light is transmitted in the column of light transmissive fluid through the light absorbing medium until exiting a light outlet end of the column. The invention has applicability to the field of fiber optics and downhole applications of lasers, such as for wellbore drilling and completion activities.

    摘要: A rotary joint for use in directional control of a subterranean rotary steerable drilling apparatus. The rotary joint is formed by mated spherical-shaped sockets, each of which is connected with a hollow rod. By virtue of this arrangement, a continuous passageway is provided for fluid to flow through the rotary joint, which fluid may be used for cooling the rotary joint during operation of the rotary steerable drilling system.

    摘要: A method for purging of, and debris removal from, a hole created with laser energy in which a swirling purge gas stream is provided in a hole containing debris to be removed, imparting a swirl to the debris and lifting the debris from a bottom of the hole. In accordance with one embodiment, the purge gas is swirled in a purge gas nozzle providing purge gas into the hole. In accordance with another embodiment of this invention, the purge gas is swirled directly in the hole.
