摘要: Abstract A new model has been developed which describes the acidization of sandstone cores. The results show that reaction hydrofloric acid with dissolvable minerals occurs in a narrow zone moves as front through core. width is related to Damkohler Number and velocity capacity number. virtually no adjustable parameters agrees extremely well experimental results.
