| titleOfInvention | Composition for calcium salt prevention |
| abstract | FIELD: oil, gas and coke-chemical industries. n SUBSTANCE: invention relates to oil production, namely to compositions for preventing deposition of inorganic salts during oil production and transportation. Composition for preventing calcium salts, including nitrilotrimethylphosphonic acid - NTP, oxyethylenediphosphonic acid - OEDP, monoethanolamine - MEA, methanol and water, additionally contains modifier - neopentyl polyol containing in molecule neopentyl fragment - 2,2-bis(hydroxymethyl)propane-1,3-diol, 2,2-dimethylol propane or trimethylol propane, wherein NTP, OEDP and MEA it contains in form of a mixture in molar ratio of NTP/OEDP = 1.0–2.4 and molar ratio MEA/∑(NTP + OEDP) = 3.7–4.4, solvent in form of a mixture of methanol and water with weight ratio CH 3 OH/H 2 O = 0.4–1.0 at following ratio of components, wt. %: mixture of NTP, OEDP and MEA 30.2–33.7, modifier 0.5–2, solvent is the rest. n EFFECT: technical result is higher efficiency relative to deposits of calcium carbonate and sulphate in conditions of high mineralization of formation water with provision of stability at low temperatures. n 1 cl, 26 ex, 4 tbl |
