[0002] An acidizing temporary plugging agent is a chemical substance used in oil and gas well acidizing operations, which mainly functions to temporarily reduce the permeability of a formation or plug high-permeability oil layers. The acidizing temporary plugging agent can rapidly form a thin and dense temporary plugging zone in the oil layer under the action of pressure difference after being injected into a well, and can be self-unplugged or manually unplugged after a certain period of time, thereby achieving the purpose of uniform acidizing.
