The invention relates to a high sulfur-containing gas well gas testing commissioning operation temporary plugging agent, concretely relates to the temporary plugging agent for guaranteeing operation construction safety and protecting a reservoir during a high sulfur-containing gas well gas testing commissioning operation process, the temporary plugging agent consists of a swelling material, a bridging material, a filling material and a suspending agent. By temporarily blocking a canon eye near bore zone by the temporary plugging agent, the complex cases of well leakage or overflow due to a lower tubing string during the high sulfur-containing gas well gas testing commissioning operation can be effectively avoided, the reservoir can be protected, acid dissolution rate of the formed temporary plugging agent is greater than 90%, the temporary blockage strength is greater than 10 MPa, and the expiration date of high temperature (130 DEG C) can reach more than 15 days.
