Description
Technical field
The present invention relates to oil and gas exploration drilling well Pollution abatement technical field, exactly relate to a kind of treatment process that is applied in the oil and gas well drilling operation discarded slurry.
Background technology
The drilling well discarded slurry is a component part important in the oil and gas well drilling process, it often is referred to as " blood " of drilling well in the sector, it just becomes discarded slurry after drilling operation is finished, general a bite well is because of the difference of institute's drilling depth, with the discarded slurry that produces 300～400 cubic metres, it mainly is by clay, drilling cuttings, high-density weighting material, various chemical additives (generally reaching 40～50 kinds of inorganic and organic chemistry treatment additives), inorganic salt, the heterogeneous stable suspersion liquid mixture that oil is formed, its composition is complicated especially, pollution hazard is big, the pH value is high: be generally 8.5～10.0, have up to 11.0; COD is up to 10000～100000mg/L; Oil-contg is also higher.
At present, domestic when disposing the oil and gas well drilling discarded slurry, mainly adopt the mode of direct landfill or solidification treatment.Because discarded slurry contains a large amount of organic and inorganic pollutants, directly landfill can produce serious pollution and harm to surface water, underground water and soil; Solidification processing method can solve the pollution hazard of discarded slurry substantially in the short period of time, but in the long run, cured block is embedded in the underground for a long time, and a series of variations will take place its inner drilling well discarded slurry, thereby cause the pollution of edatope; And the soil after solidifying has also lost cultivates value.Therefore; in order to realize to the recycle truly of oilfield drilling operation discarded slurry; preserve the ecological environment, guarantee the Sustainable development of oil-gas drilling exploitation, it is extremely urgent to explore enforcement oil and gas well drilling discarded slurry harmlessness disposing new technology.
At this situation, there are indivedual companies to adopt the technology of microorganism, soil and plant combined processing oil and gas exploration drilling well discarded slurry at present, the concrete technical scheme of this technology comprises:
A kind of waste mud in petroleum and natural gas exploration drilling work treatment process is characterized in that step comprises:
A, microbiological treatment: the weight ratio of special microorganism strain by 5: 100 is added in the discarded slurry, mixes; And the weight ratio of natural soils by 2: 1 be added in the discarded slurry of having sneaked into special microorganism strain, mix, thereby form the microbiological treatment layer; Described special microorganism strain is the bacillus megaterium (Bacillus megaterium) in Halomonas ventosae bacterium, Halomonas campisalis bacterium and the bacillus in the salt zygosaccharomyces;
B, soil treatment: at the microbiological treatment laminar surface that a step forms, cover the natural soils of 10-15cm, form the soil treatment layer;
C, plant treatment: on the surface of soil treatment layer, plantation pulse family class and non-pulse family parasymbiosis nitrogen fixing tree are perhaps planted herbaceous plant, form the plant treatment layer.
In the described c step, described pulse family class and non-pulse family parasymbiosis nitrogen fixing tree are Leucaena leucocephala (L.) or alder.
In the described c step, described herbaceous plant is Chinese silvergrass or trifolium.
In the described a step, Halomonas ventosae bacterium is 4 strains, and Halomonas campisalis bacterium is 1 strain, and bacillus megaterium (Bacillus megaterium) also is 1 strain.
In the described a step, the natural soils of adding through airing after, and to be adjusted to water content be that 15-20%, particle diameter are the soil of 0.5-1cm.
In the described a step, the water content of microbiological treatment layer is 20-30%.
In the described b step, natural soils are through after the airing, and to be adjusted to water content be that 15-20%, particle diameter are the soil of 0.5-1cm.
