The invention relates to the technical field of well cementation, in particular to an integrated well cementation fluid system and application thereof. The invention provides an integrated well cementation fluid system. The integrated well cementation fluid system comprises cement paste and epoxy group flushing fluid, the volume ratio of the cement paste to the epoxy group flushing fluid is (4-9): (1-6); the cement paste is prepared from the following components in parts by mass: 100 to 1200 parts of cement, 0.5 to 12 parts of expanding agent, 1 to 40 parts of latex, 2 to 45 parts of reinforcing agent, 5 to 32 parts of fluid loss agent, 250 to 800 parts of water and 0.1 to 10 parts of defoaming agent. The integrated cementing fluid system is more stable in performance, better in cleaning effect and simple in technological process while meeting the environmental protection requirement. 本发明涉及固井技术领域，尤其涉及一种一体化固井液体系及其应用。本发明提供了一种一体化固井液体系，包括水泥浆和环氧基冲洗液；所述水泥浆和环氧基冲洗液的体积比为(4～9)：(1～6)；按质量份数计，所述水泥浆包括以下组分：水泥100～1200份，膨胀剂0.
