Multi-scale pore structure transformation of shale under mixed acid acidification method

Multi-scale pore structure transformation of shale under mixed acid acidification method

Most of the acid fluids used in the existing acidfrac process have the shortcomings of plugging pores, polluting formation and poor effect. The method of adding nitric acid in a specific proportion to conventional acid can avoid the above problems to a certain extent. A mixture of HCl: HF: HNO3 (3:1...
