Abstract
Provided herein is a separating device for removing sand and rock particles in the extraction of liquids or gases from wells drilled in rock having a plurality of brittle-hard annular discs stacked one on top of another and axially braced by a supporting structure. The annular discs have at least three spacers uniformly distributed over the circumference on their upper side. The discs are stacked on each other such that the spacers lie one over another and a separating gap with a height of 0.05-1 mm, preferably 0.2-0.5 mm, is present between each of the discs. Similarly, another embodiment of the separating device has a plurality of brittle-hard bush-shaped elements with slits formed therein.
Claims19
A separating device for removing sand and rock particles in an extraction of liquids or gases from wells drilled in rock, comprising a plurality of annular discs (1) of a brittle-hard material stacked one on top of another and axially braced by a supporting structure (7) having springs (15) configured to avoid widening of a gap between the supporting structure and the stack of annular discs, the discs (1) having on their upper side (2) at least three spacers (3) uniformly distributed over a circular circumference of the discs (1), the discs (1) being stacked one on top of the other in such a way that the spacers (3) respectively lie one over the other, and that a separating gap (5) with a height of 0.05-1 mm is present in each case between the individual discs (1).
