Solvent for solid crude oil deposits, containing an organic extracting substance, distinguished by the fact that it contains a neutral transporting fluid (TF), a dissolving (extracting) substance (DS) and a surfactant in a specific ratio of constituents (mass %) - DS:5-60; surfactant: 0.01-0.8; TF:39.2-94.99. The solvent contains water as the TF, and aromatic, alkyl-aromatic and aliphatic hydrocarbons fractions, and mixtures of these fractions in any mass ratio as the DS. |
