Method and apparatus for separating solid phase from drilling mud

Patent ·
OSTI ID:5528087
A method is disclosed for separating solid phase from driling mud, comprising forming from drilling mud an adhesive layer on a rotary closed curvilinear surface partly placed in the drilling mud, with subsequent feeding of an ionized gas jet along a tangent line to the adhesive layer, the gas jet entraining and removing solid phase particles from the drilling mud. The linear velocity of the adhesive layer in the zone of its contact with the gas jet is controlled by changing the velocity the gas jet. An apparatus for carrying out the method comprises: a tank filled with drilling mud accommodating a drum installed for rotation for forming an adhesive layer of drilling mud on its cylindrical surface during rotation of the drum; a nozzle which is arranged in parallel to a tange line to the drum surface and communicates with a source of a gas under pressure for forming a jet gas that entrains and removes solid phase particles from the drilling mud; a pair of electrodes connected to a high-voltage d-c supply source for ionizing the gas jet.
