The investigation of influence of explosion-forming substance volume and location in bank on displacement efficiency of mixtures from the layer model
I.A. SharonovaIn the article the results of oil mixtures and formation water displacement from porous medium via bank with explosion forming substance are given. The mixtures of formation hard and alkaline waters and oils with different rheological properties have been studied. It was established, that in other equal circumstances the bank enhancement via explosion forming substance promotes displacement efficiency increase for 10-12 %. It was shown, that the best result is achieved, when the 40 % volume of bank is enhanced via SIJ-26 polymer type within 1.2 %, which allows to raise stability and elasticity of bank for 25-30 %. The practicability of explosion-forming substance bank injection with the following order has been justified: first the 40 % of bank volume is injected, then the explosion forming substance in 30 % from the bank, and then remaining 30 % of the bank and the mixture are interfused in porous medium with oxygen-containing gas compressed by air.
