FIELD: oil production, particularly for preventing salt formation in produced fluid in bottomhole zone, on pumping equipment inside wells characterized by different reservoir pressure and by extractable liquid temperature up to 95°C.
SUBSTANCE: composition includes oxyethylidenediphosphonic acid and building oil asphalt. The composition additionally has polypropylene. The components are taken in the following proportion (% by weight): oxyethylidenediphosphonic acid - 5-80, polypropylene - 1-10, remainder - building oil asphalt.
EFFECT: reduced time of equipment protection against salt formation due to reduced speed of carrier substance solution during oil production with different yields, water content, produced water mineralization and with extractable fluid temperature up to 95°C.
