Experimental studies of the effect waterproofing compounds on the permeability of saturated sandstones

摘要

The authors describe a series of experiments conducted to develop compositions with optimal concentrations of reagents, ensuring the creation of durable low-permeability waterproof barrier in lowmineralized reservoir water presence in holebottom region. Theoretical and experimental researches have explained the mechanism of physical-chemical sedimentation of reservoir by silicate-hydrolysis-lignin solution. The article contains experimental results and recommendations for the use of different compositions and sequence of carrying out the primary steps of waterproofing.
