| Abstract: | HGA 1 is a double fluid chemical agent. Fluid A is a hydrochloric or mud acid solution containing surfactants, corrosion inhibitor and organic aminocompound (OAC), B is a solution of inorganic sodium salt (ISS) and surfactants. Being injected into the near borehole zones, A and B are mixed and form foam, OAC and ISS react to generate N 2 gas and heat, the acid foamed slowly dissovles various reservoir blockages and rock minerals. The field tests on HGA 1 in two water injection wells for blockage relieving and enhancing water injectivity are successful. For formulating HGA 1, the effects of molar ratio and concentration of OAC and ISS, type and concentration of acid, environmental temperature of reaction, concentration of surfactants (ABS, OP 10) on N 2 gas and heat generation are studied. |
