Abstract

A complex study of surface-active substance SCA-515 containing Neonol AF 9-12 - oxyethylated monoalkylphenol as a nonionic surfactant has been performed. It is shown that the SCA-515 does not interact with the deposit water, shows demulsifying properties, reduces the interfacial tension to ultralow values, adsorbs slightly on the core. The effects of ionic strength and nature of electrolyte on the surface properties of surfactant have been studied. The composition of the punching liquid for secondary access technologies based on the surface-active substance SCA-515 and an aqueous solution of potassium chloride has been found. Researches of the designed punching fluid have shown its high inhibitory ability, compatibility with formation fluid and mud filtrate. Industrial (Peschanoozerskoe field) tests have shown high efficiency of surfactants: flow rates increasing, the term reduction of well development and decrease of skin effect.
