Study of Nanobentonite Suspensions Parameters to Create Ecological Safely Technologies

The paper deals with enrichment problems and research of rheological properties of aqueous suspension of montmorillonite clay as well as its swelling process. Due to the conducted investigations, it has been determined that its enrichment with the nanosize particles can be achieved by regulation of the granulometric composition of the crude montmorillonite clay. The rheological properties of suspension and swelling of enriched and unenriched clays have been studied due to the comparison of results. It has been shown that these properties in enriched bentonite are more pronounced. The new composition of fringe based on nanobentonite and technology of its use for enhanced oil recovery of heterogeneous reservoirs have been developed by using these properties of enriched bentonite.
