PBS (Phosphate Buffer Solution) fusion technical system of poly-surfactant and synergistic technology

The invention discloses a poly-surfactant and synergistic technology PBS fusion technology system, which comprises a composite surfactant, an amphiphilic poly-surfactant and an ion auxiliary agent, the composite surfactant is prepared from the following components in percentage by weight: 13.0 to 15.0 percent of isomeric alcohol ether polyoxyethylene ether hydroxypropyl dialkyl carboxyl betaine, 8.0 to 12.0 percent of fatty acylamino propyl dimethyl carboxyl betaine, 5.0 to 8.0 percent of alkanolamide, 4.0 to 10.0 percent of fatty alcohol polyoxyethylene ether (2) sodium carboxylate component, 4.0 to 8.0 percent of cosolvent, 0.5 to 1.5 percent of complexing agent and 65.5 to 45.5 percent of water. The surfactant can achieve the effect of three-component combination flooding, can reduce the scaling problem of three-component combination flooding, is a novel single-component chemical displacement agent multi-component graft copolymer surfactant, and can show the dual characteristics of the surfactant and a pol
