摘要
The boring fluid suspension, the composition of which is not as required, is subjected to a separating process in two stages, for its adaptation to the conditions prevailing in the hole being bored into the earth by a rotary drilling head. The stages comprise screening and pressure filtration. The boring fluid still adhering to the solid matter held back by the screen, is sucked away by vacuum. The fluid resulting from the separation process is delivered for the desired adjustment of the composition of the boring fluid, to the suspension storage tanks. The solid matter obtained is dried and processed for the recovery of solid matter to be used in the boring fluid suspension. Provides a method by which the composition of the boring fluid suspension can be adjusted to suit the conditions in the borehole. At the same time, the loss of material and the consequent pollution of the environment are kept as low as possible, without prejudice to the economics of the boring operation.
