Experimental study of acidizing diversion effect on different permeability of heterogeneity sandstone reservoirs
Abstract In the paper, the diversion laws between VES acid and heterogeneous sandstone were carried out by diversion acidizing experiments. The results showed that the viscoelastic surfactants of diversion acid reached the maximum value at hydrochloric acid concentration between 5 and 11%, when high...

| description | Abstract In the paper, the diversion laws between VES acid and heterogeneous sandstone were carried out by diversion acidizing experiments. The results showed that the viscoelastic surfactants of diversion acid reached the maximum value at hydrochloric acid concentration between 5 and 11%, when higher than 13% and the diversion acid with low viscosity which was beneficial to acid injecting construction. The results of parallel core experiment revealed that diversion acid has better divert effect in the reservoir with better homogeneity, and injected acid PV of diversion acid conforms to the Darcy’s law when the permeability of glass core is less than 1000 mD. From the overall results, it can be concluded that diversion acid is suitable for heterogeneous sandstone reservoirs, and the conclusion is suitable for pilot tests in oil field. |
