Zusammenfassung:	FIELD: oil extracting industry. SUBSTANCE: compound has, in percents of mass: hydrocarbon fraction at 70-165 centigrade, received from benzine fraction of reforming process with addition of 15.9-17.3% dicyclopentadiene, or said fraction, received by means of rectification of liquid pyrolysis products, which has 15.9-17.3% cyclopentadiene and dicyclopentadiene mixture - 98.8-99.2, surface-active substance - 0.3-0.5 and polar nonelectrolyte - 0.5-0.7. EFFECT: increased speed of asphalt-resin-paraffin sedimentations removal and increased dissolvent capacity. 4 tbl
