| description | The invention relates to the technical field of oil field water plugging agents, and discloses a high-strength high-temperature acid fracturing temporary plugging agent and a preparation method and application thereof. The high-strength high-temperature acid fracturing temporary plugging agent comprises the following components in parts by weight: 20-45 parts of polyvinyl alcohol; 15-40 parts of polylactic acid; 1-36 parts of an inorganic salt; 0.02-0.16 part of a composite plasticizer; 0.02-0.3 part of a silane coupling agent; 0.02-0.2 part of a cross-linking agent; and 0.1-1 part of an auxiliary modifier. The high-strength high-temperature acid fracturing temporary plugging agent is high in bearing strength; the dissolving time is controllable; the dispersibility in the dissolving process is good; high temperature resistance is realized; the compatibility is good; the raw materials are cheap and easily available; and the preparation process is simple and convenient for grinding.
