The physical and chemical properties of non - active nitric acid powder were introduced. The dissolving power of the non - active nitric acid powder and its difference from the conventional acidizing process were analyzed. The factors that increased the yield of non - active nitric acid powder acidizing process were analyzed. Field tests show that the nitric acid powder with other acids used in conjunction, can increase the acidification area, reduce acidification costs, but also can effectively reduce the formation of secondary pollution. The special role of non-active nitric acid in the acidification process was discussed. The process is simple and easy to implement, increase production significantly.
