FIELD: process engineering.SUBSTANCE: invention relates to reclamation of soils contaminated in oil-and-gas production. For reclamation of soils special site is arranged to make soil-slime mix by mixing drilling slime, said and peat, to be held for definite time and delivered to application point. Mote here that drill cuttings are transferred to said site by specially equipped dump trucks as well as peat and sand. In compliance with the first version, the mixes are dumped to make three enclosed rolls to be mixed by excavator. In compliance with the second version, peat, sand and slime are uniformly spread in 15-20 cm-thick 100 m-long and 2.0-2.5 m-wide bay and mixed by cutter. Now, the mix is cured for 1-30 days to level moisture content of mix pile and to make equal to from 10±5% up to 40±10% .EFFECT: better environmental conditions. |
