NOVELTY - Modified nano foam stabilizer obtained by copolymerization modification of a nano substrate, a polymer monomer and a surface active monomer. USE - The modified nano foam stabilizer is useful in effect of stable foam, and in oil field technology (claimed). ADVANTAGE - The stabilizer: can enhance stability of foam in high temperature and high salt environment, and does not reduce foam volume. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing modified nano foam stabilizer comprising copolymerizing a solution I containing a nano substrate, a polymer monomer, a surface active monomer, and an initiator, to obtain the modified nano foam stabilizer.
