Petroleum and natural gas well drilling waste landfill technology

The invention discloses a petroleum and natural gas well drilling waste landfill technology. The petroleum and natural gas well drilling waste landfill technology comprises the following steps that (1) a landfill pool is dug, reinforced concrete C25 is poured on the pool bottom and the pool wall at the thickness of 20-25 cm, after pouring is completed, an impermeable layer composed of non-woven geotextile, high-density polyethylene geomembrane and non-woven geotextile is arranged in the landfill pool, the periphery of the impermeable layer is fixed into anchoring ditches on the periphery of the landfill pool; (2) solidified body waste is fed into the landfill pool, and then back wrapping of the impermeable layer is conducted; (3) after natural air drying is conducted for 25-35 days, a C20concrete sealing cover layer which is 10 cm thick is poured on the surface of the solidified body waste; (4) after air drying is conducted for 28-33 days again, the surface of the concrete sealing cover layer is covered by me
