Dewaxing agent and natural gas dewaxing treatment method

The invention relates to a dewaxing agent and a natural gas dewaxing treatment method, and belongs to the technical field of natural gas treatment. The dewaxing agent comprises, by weight, 0.1-20% of polyisobutene, 0.1-30% of ethylene glycol, 0.5-10% of a surfactant and 40-99% of alkane. The alkane is at least one of straight-chain alkane of C5-C35 and cycloalkane of C5-C35. According to the present invention, the solid wax can be well dissolved by the dewaxing agent; the boiling point of the dewaxing agent is increased, and the freezing point of the dewaxing agent is reduced; the surface tension of the dewaxing agent is increased, so that all the components in the dewaxing agent form a synergistic effect; and by matching with the surfactant, the components in the dewaxing agent form a uniform system, so that the dissolution of the solid wax is further promoted, the viscosity of a liquid system is reduced, the adhesive force of the solid wax on a metal wall surface is reduced, the deposition of the solid wax
