Zusammenfassung:The invention relates to a composite synergistic discharge aiding agent and a preparation method thereof, and belongs to the technical field of oil and gas exploitation. Comprising the following components in parts by weight: 2-3 parts of betaine, 5-8 parts of fatty alcohol-polyoxyethylene ether, 2-4 parts of didodecyl trimethyl ammonium chloride, 10-15 parts of alkyl glycoside APG 1214 and 70-81 parts of water. The composite synergistic discharge aiding agent disclosed by the invention does not contain fluorine, and can effectively solve the problem that the existing discharge aiding agent is harmful to the environment and human bodies. In the used materials, such as didodecyl trimethyl ammonium chloride, the didodecyl trimethyl ammonium chloride has good compatibility with betaine and fatty alcohol-polyoxyethylene ether, so that the surface and interfacial tension of the fracturing fluid of the oil and gas field can be reduced. The composite synergistic discharge aiding agent can be prepared on a constructi
