Multi-hydrogen Acid MF

Multi-hydrogen acid is a kind of multi-grade acid system to meet the requirement of deep acidizing operation. It is a kind of retarder, which has the function of multi-grade ionization. There are several H⁺ on the body of the molecular of multi-hydrogen acid, and the activities of those H⁺ are different according to their situation but the H⁺ on each grade is similar. When it was used, with the effect of the condition of formation, the more active grade of H⁺ of multi-hydrogen acid firstly produce ionization reaction to provide acid function, then is the second ionization, and react in sequence. That can ensure the gentle release of H⁺ and the balanced concentration of hydrogen ion, and also can decrease the damage of the wells’ nearby. It is supposed to make strong the acid performance of plug removal in the depth. And at the same time, the multi-hydrogen acid has the functions of complexation, anti-emulsification, and anti-acid sludge. In addition, it has a strong adsorption performance with clay and rock. It is a good retarder of HF acid.
