| titleOfInvention | Composition for removing asphaltene-tar-paraffin deposits |
| abstract | FIELD: oil and gas production. SUBSTANCE: composition contains hydrocarbon solvent and additive: mixture of 47.5-49.95% of nitrogen-containing ethylene oxide/propylene oxide block copolymer with molecular weight 5000 and 47.5-49.95% of isopropylbenzene- polyalkylbenzene tar with 0.1-5.0% of polyglycols at weight ratio 1:1?0.002- 0.1), respectively. To improve working characteristics of additive under winter conditions, it can be used in the form of solution in alkylbenzene fraction at weight ratio 1:1, said alkylbenzene being, in particular, isopropyl-, ethyl-, or butylbenzene. EFFECT: improved deposit removal efficiency both in summer and winter periods. 2 cl, 7 tbl, 4 ex |
