The invention provides a method for maintaining flow conductivity of seams near the wellbore area. The method comprises the steps of firstly, preparing a temporary plugging steering working solution, wherein the temporary plugging steering working solution comprises degradable temporary plugging agents, an equidensity proppant and a low-viscosity carrying liquid; carrying out staged fracturing, wherein the pump injection sequence is a prepad fluid, a sand-carrying fluid and the temporary plugging steering working solution; and after complete fracturing, waiting till the temporary plugging steering working solution is degraded, carrying out fluid drainage, and ensuring that the proppant remains at the seams and forms a seepage channel. According to the method, the degradable temporary plugging agents are formed through mixing multi-scale combined degradable temporary plugging agents according to a certain proportion, the large-particle degradable temporary plugging agents are blocked at the end openings of the seams, and the clearances among the large-particle degradable temporary plugging agents are filled with the small-particle degradable temporary plugging agents, so that the plugging effect is effectively and quickly improved, after fracturing, the degradable temporary plugging agents and the proppant exist in the hydraulic fracture seams, after the degradable temporary plugging agents are degraded, the proppant maintains the flow conductivity of a near mineshaft, the risk that the seams near the wellbore area are closed and do not have the flow conductivity is reduced, and seepage channels of a gas reservoir and a mineshaft are maintained.
