FIELD: oil and gas production.
SUBSTANCE: invention can be implemented in oil processing and petrochemistry. The essence of the invention is as follows: ammonia heptamolybdate is subject to interaction with dialkyldithiophosphorus acid at mole ratio of ammonia heptamolybdate:dialkyldithiophosphorus acid equal to 1.0:18.5-22 at presence of aprotonic solvent. Further, prepared molybdenum complex is treated with alkenylsuccinimide at weight ratio correspondingly, 1.0:0.35-0.45. Treatment with alkenylsuccinimide is preferably carried out in medium of mineral oil taken in amount of up to 1.44 wt parts per 1 part of molybdenum complex.
EFFECT: improved antifriction and tribological properties, reduced volume of waste water.
