IMPACT ASSESSMENT OF VARIOUS COMPOSITIONS AND COMPLEXES OF SPACER FLUIDS ON THE DENSITY OF CONTACT OF THE GROUTING STONE WITH CONTIGUOUS MEDIA IN THE INTER-COLUMN SPACE
The paper presents the results of laboratory studies to assess the washing capacity of various spacers, including detergent, sodium metasilicate and an adhesive additive. The complex of theoretical and experimental studies performed in this work allowed us to visually evaluate the effectiveness of buffer fluid compositions for the use of polymer-clay drilling mud using the developed methodology.
