Efficient cleanup additive for continental facies shale and preparation method of efficient cleanup additive

The invention relates to an efficient cleanup additive for continental facies shale. The efficient cleanup additive comprises a fluorocarbon surfactant, a hydrocarbon surfactant and a fluorosilicone surfactant; the mass ratio of the fluorocarbon surfactant to the hydrocarbon surfactant to the fluorosilicone surfactant is (2-3): (5-7): (8-10); perfluorohexyl polyvinyl ether sulfonate is adopted asthe fluorocarbon surfactant; N-dimethylaminopropyl-N-triethoxysilane is adopted as the fluorosilicone surfactant; and octadecyl dihexyl betaine is adopted as the hydrocarbon surfactant. The efficientcleanup additive for the continental facies shale can effectively increase a contact angle and reduce capillary resistance while reducing surface and interface tension, has an amphiphobic effect, andcan be used for continental facies rock reservoirs with the characteristics of high water saturation, poor self-absorption capacity, high adsorbed gas content and the like. 本发明涉及一种陆相页岩用高效助排剂，包括氟碳类表面活性剂、碳氢类表面活性剂和氟硅表面活性剂，且氟碳类表面活性
