| Abstract: | Plugging removal with high pressure pulse jet acidization is new technique to be used for increment of production and injection in low permeability oil fields. Acidizing fluids' type, concentration, jet pulse frequency, treatment time and interval treated may be selected according to degree of formation plugging. In terms of hydrodynamics and acidizing theory, this paper discusses the basic principle, technology and calculation method concerned of plugging removal technique with high pressure pulse jet acidization, and the obvious effect of the technique is proved by actual well examples. |
