Research of influence of fractional composition of bentonite clay on plug appearance in gas-lift wells
The article presents results of studies aimed at prevention of fallout of a solid phase contained in a 3,5 % gas liquid mixture while lifting mixtures with Newtonian properties. It is substantiated that while introducing some gas liquid mixture containing a considerable quantity of sand of 0,50...0,85 mm diameter into a composition there exists possibility of preventing their fallout by means of 0,011 % nanoparticles injection of clay from Goy-gol or Hyrdalan into a mixture composition. Results of studies of clay swelling from Goy-gol, Shamkhor and Hyrdalan in alkaline water of a formation are presented.
