Synthesis of Viscosity-Variable Diverting-Acid Main Agent and Diverting Performance Evaluation
Keyword(s):
The viscoelastic surfactant diverting-acidification technology is a new intelligent matrix acidizing technology.Based on the theoretical analysis,viscosity-variable diverting-acid main agent is selected out.Both the rthogonal design and the grey relational analysis are used to determine synthesis conditions and influence of reaction factors.The production structure is verified by the infrared spectra.Then coreflooding experiments are designed to check the diversion effect,and it shows that the system satisfies the need of diverting-acidification in the carbonate formation.
