Scale inhibition fracturing fluid and preparation method thereof

The invention discloses a scale inhibition fracturing fluid and a preparation method thereof, and belongs to the technical field of fracturing fluids. The scale inhibition fracturing fluid specifically comprises the following components in parts by weight: 0.5-5 parts of a modified cellulose thickening agent, 5-10 parts of a composite scale inhibitor, 1-5 parts of a gel breaker, 0.5-3 parts of an emulsifier, 0.5-3 parts of a fluorocarbon surfactant and 120-180 parts of water. The composite scale inhibitor, the modified cellulose thickening agent, the fluorocarbon surfactant and the like are compounded together to prepare the fracturing fluid with the anti-scale effect, the composite scale inhibitor can enable ions such as calcium and magnesium to be not prone to being combined with carbonate to form scales through the ion exchange effect, and therefore the scale inhibition effect is achieved; the modified cellulose thickening agent can further prevent generation of inorganic salt precipitation, and the fluoro
