Improving the effectiveness of acid treatment of wells is an important task. One of the trends in this area is the use of selected high quality acid compositions. The main types of additives for preparing acid compositions are demulsifier, corrosion inhibitor, dispersant, stabilizer iron and mutual solvent. Varying concentrations and ratios of reactants can adjust the properties of the acid composition. The dependence of the contact angle and interfacial tension of the content demulsifier compatibility acid composition of the oil on the concentration of iron and the presence of the stabilizer, and studied the changes of reservoir properties rocks exposed on the core material acid composition based additives ITPS. The methodology of testing acid composition in relation to the given conditions is suggested. Source
