FIELD: chemistry.
SUBSTANCE: conducted is the separation of drilling fluid on the drilling mud and the cleaning fluid, returning the later to the drilling process, supplying the drilling mud to the bioreactor with layer by layer arrangement in the following order: plamilon, additional soil, drilling mud, then aeration, adding of diammophos in the quantity 0.1-0.3 wt %, and the association of petroleum decomposing microorganisms and organic additives to the drilling fluid Rhodococcus erythropolis "АС-1339Д" and Fusarium sp. №56 in the ratio 1:1. In conjunction with the specified association is added plamilon as the structure-forming agent.
EFFECT: increase in the effectiveness of utilisation of oil-rig wastes.
