Method for realizing temporary plugging redirecting multiple crack fracturing inside horizontal well section

The invention relates to a method for realizing temporary plugging redirecting multiple crack fracturing inside a horizontal well section. The method comprises the following steps: firstly preparing a temporary plugging redirecting working liquid which includes a degradable temporary plugging agent, degradable fibers, and a low-viscosity transport liquid; conducting sectional fracturing, and conducting pump casting in an order of a preset liquid-a sand carrying fluid-the temporary redirecting working liquid; and after the completion of the entire fracturing, waiting for the temporary redirecting working liquid to degrade, and discharging the temporary redirecting working liquid. According to the method, plugging efficiency is increased through the adoption of the multiple dimension degradable temporary plugging agent, leakage loss among inter-crack liquid is reduced, and plugging success rate is increased. After construction, the degradable temporary plugging agent, and the degradable fibers are completely de
