In this paper, the cause of blockage in a heavy oil field well is analyzed, and a new solid acid plugging removal system is adopted, which achieved good plugging removal and injection effect in field application. The solid acid plugging removal system is a new type of oilfield multi-dimensional three-dimensional plugging removal system, which belongs to the polyhydroic acid system, combined with the lipophilic surfactant factor, and has various functions such as dissolution penetration, broken chain degradation, sterilization and anticorrosion, and three-dimensional dispersion. Through the evaluation of compatibility, dissolution and corrosivity of the solid acid plugging removal system, solid acids perform well. The plugging removal effect of an oilfield is remarkable, the acid system is suitable for the near well blockage or deep blockage of the heavy oil block well, which can relieve the blockage of inorganic matter, and also relieve the blockage of some organic matter and crude oil or microorganisms. Solid acids are superior to conventional acids in transportation, preparation and use, and have good application prospects.
