Temporary plugging and fracturing process in degradable fiber clearance

The invention relates to a novel temporary plugging and fracturing process in a degradable fiber clearance. According to the temporary plugging and fracturing process, work liquid composed 1.0%-2.0% of degradable polyester fibers, 0.45% of linear glue and 20%-35% of propping agents is poured into a fracturing layer section, and a plurality of branch cracks are generated. The temporary plugging and fracturing process has the advantages that operability of the construction process is strong, the branch cracks are formed in a fracturing mode, the oil drainage area is expanded, fracturing yield is improved, an effective driving system can be built through a formed branch crack system and a well, cost is low, and the exploitation benefit of an oilfield is greatly improved, and the problems that permeability is low, exploitation is hard and the reserve fracturing reforestation effect is poor are solved.
