The invention relates to the technical field of fracture acidizing of oil fields, in particular to a tip screen-out fracturing method. The tip screen-out fracturing method comprises the steps that firstly, a prepad fluid is pumped into a fracturing formation; secondly, and when a major fracture of the fracturing formation grows to a target fracturing design value, efficient filtrate-loss reducingliquid is pumped; thirdly, when the efficient filtrate-loss reducing liquid is pumped and pressure is increased, sand-carrying fluid is pumped; and fourthly, displacing liquid is injected, and oil andgas production is tested. According to the tip screen-out fracturing method, when the efficient filtrate-loss reducing liquid is pumped, it is not required to change the construction displacement, the construction procedure is simple, and field operation is facilitated. The efficient filtrate-loss reducing liquid contains a cleanup additive, a clay stabilizer and a gel breaker, the damage of a filtrate to the formation can be reduced, and after five hours, the residual rate of the filtrate-loss reducing liquid is about 30%; compared with the prior art, the fracturing yield of the tip screen-out fracturing method is increased by 80%-160%, and the stable production period after fracturing is prolonged by 2-3 time; and after the method is adopted, the yield-increasing effect obtained after fracturing is obvious, and no phenomenon of near-well pressure channeling occurs.
