FIELD: oil and gas production, particularly reclamation of surface-mined areas and building of oil and gas wells in ground.
SUBSTANCE: method involves covering industrial area F with gravel layer having thickness of 20-30 cm; laying pipeline along protecting ground embankment surrounding drilling site D, wherein the pipeline is provided with waste water outlet nozzles, which discharge waste water into industrial area F; periodically removing drill waste water obtained during well drilling with the use of low-toxic water-based drilling mud and periodically discharging said waste water onto gravel covering of subsurface horizon B1 of industrial area F to prevent subsurface horizon A topsoil contamination and to decrease dusting in drilling site D. Method is the most efficient in the most dry season.
EFFECT: prevention of fertile land contamination along with drilling cutting dehydration in earth storage by drilling waste water discharge to soak way.
