INVESTIGATION OF THE EFFICIENCY OF THE TURBULIZING-ABRASIVE ADDITIVE IN BUFFER LIQUIDS "SDIR"
A laboratory installation has been created to investigate the washing-abrasive action of buffer liquids used in cementing casing strings in wells. Unlike the known installations intended for the same purposes, in the new installation the geometrical, hydraulic and technological similarity to the real conditions is observed to a great extent. The studies carried out on the installation showed that the effectiveness of the action of buffer liquids in removing and displacing clay and other residues from the annular of the well can be significantly increased by adding in the liquid the turbulent abrasive additive proposed by the authors.
