FIELD: petroleum and gas industry. SUBSTANCE: composition for removing and preventing formation of asphaltene-resin-paraffin-hydrate deposits in oil and gas wells and pipelines comprises alkali metals, aluminium, and/or calcium, and/or magnesium, and/or iron, and/or silicon, in the following weight ratio, mass%: aluminium, 1.5-15; calcium, 1.0-60; magnesium, 1.0-25; iron, 1.0-10; silicon, 1.0-5. Method resides in feeding said composition comprising above-mentioned metals taken in weight ratio into well using standard lubricator enclosed in container made in the form of pipes made of aluminium, and/or iron, and/or calcium, and/or magnesium, and/or silicon. EFFECT: higher efficiency. |
