Composite oil gel and preparation method thereof

The invention discloses a composite oil gelling agent and a preparation method thereof, and belongs to the technical field of oil gels, and the method comprises the following steps: co-dissolving ethyl cellulose and a small molecule oil gelling agent in an organic solvent to obtain a spinning solution, and carrying out electrostatic spinning by using the spinning solution to obtain the composite oil gelling agent, the prepared oil gel does not need to be heated, can be used at high temperature, normal temperature and low temperature, can be formed only by uniformly stirring with oil liquid, and is convenient and quick to use; different from the mode that nanofibers are dispersed in small molecule oil gel, ethyl cellulose serves as a carrier, the small molecule oil gel is loaded on the surfaces of the nanofibers of the ethyl cellulose through electrostatic spinning, the integration of the ethyl cellulose and the small molecule oil gel is better, the ethyl cellulose and small molecules are jointly dissolved in
