FIELD: construction.
SUBSTANCE: invention relates to methods of controlling filtration of contaminated effluents from earth pits - accumulators of drilling wastes from oil and gas wells. Method involves preparation of soil foundation, covering bottom and side walls of ground pit-drilling waste storage unit with straightening underlying layer, followed by placing of polyethylene film on underlying layer. Underlying layer is made by overlapped laying of empty paper bags from Portland cement, clay powder and other dry chemicals used in construction of well. Adjacent edges of overlapping laid empty paper bags are fixed with adhesive tape "Scotch".
EFFECT: reducing labour intensity and cost of construction of underlayer film impervious screen of ground pit-accumulator of drilling wastes of oil and gas wells with simultaneous recycling of industrial wastes in form of empty paper bags, accumulated in large amount on territory of drilling platform.
