Zusammenfassung:The invention discloses a high density fracturing fluid and further provides a method for preparing the fracturing fluid. To solve the technical problem, the following technical scheme is adopted, wherein a formula of the high density fracturing fluid comprises, by weight, 0.4-0.5% of a thickening agent, 25-47% of a weighting agent, 0.2-0.4% of a multi-effect additive, 0.4-0.6% of a cleanup additive, 0.4-0.6% of a cross-linking agent, 0.001-0.1% of a gel breaker, and the balance of water.
