Abstract
The invention relates to a process for recycling and treatment of oily sludge in oil fields and provides a method for effectively ensuring that the physicochemical indices of soil meet the requirements for soil remediation. The oilfield oily sludge degrading agent contains the following ingredients in percentage by weight: 0.5 to 1 percent of SG (Bacillus alcalophilus), 1 to 3 percent of yeast, 10 to 20 percent of chicken matures and the balance of distiller's grains. The method for degrading oily sludge in oil fields comprises the following steps: firstly thoroughly mixing the sludge with the degrading agent at a volume ratio of 10:1 to 50:1, then composting for 36 hours and turning over once, subsequently turning over once every10 days to every month. The method for degrading oily sludge in oil fields by using the oilfield oily sludge degrading agent can effectively ensure that the physicochemical indices of soil meet the requirements for soil remediation, can economically and effectively treat oily sludge in oil fields, and has good effects of treating heavy oil and oil sludge with high wax and gel contents.
Description
One, technical field: the present invention relates to the technology of recycling treatment oil field oil-containing mud, is the method for plain preparation of a kind of oil field oil-containing sludge degradation and degraded oil field oil-containing mud.
Two, background technology: in oilfield process, the dehydrating of crude oil of joint station, sedimentation and follow-up oily water treatment all can produce a large amount of oily sludges.The composition of oily sludge is very complicated, is mainly crude oil, silt and oilfield additive and water.At present, the treatment process of oily sludge mainly contains: solid is buried, is burned, hot washing, SX, pyrogenic silica and biological degradation method etc.All there are some problems in these methods in practical application.Big like the burning method power consumption, be prone to produce secondary pollution; The method of burying is prone to underground water and environment are polluted; Though solvent extration ability recovery part crude oil, the soil physico-chemical index after the extraction does not still reach the requirement of soil second ploughing.Biological degradation method is the method that present most economical and effective is handled the oil field oily sludge.Though biological treatment is to utilize specific oil degradation bacteria degrading crude oil, biological bacteria receives environmental influence big.Maturation process agent of patent CN101734835A oil field oil-containing mud and oil field oil sludge or sand are converted into the treatment process of organic mud or sand, but this method intractable viscous crude with contain greasy filth cured and that colloid is high.
Three, summary of the invention: the present invention provides a kind of effective realization soil physico-chemical index to reach soil second ploughing requirement, the method for cost-effective processing oil field oily sludge, and it is plain to handle the viscous crude oil field oil-containing sludge degradation satisfactory for result with containing greasy filth cured and that colloid is high.Technical scheme is that the oil field oil-containing sludge degradation is plain, and it is characterized in that: composition consists of by raw material weight per-cent: the vinasse of 0.5%～1% SG bacterium, 1%～3% yeast, 10%～20% chicken manure and surplus.The method of the plain degraded of oil field oil-containing sludge degradation oil field oil-containing mud is undertaken by following step, is to carry out thorough mixing in 10: 1 to 50: 1 by volume with oil field oil-containing mud and degradation element at first; Next stacks tipping in 36 hours to 10 days once, turns upside down once in per then 10 days to one month, and oil field oil-containing mud promptly reached the requirement of urban afforestation with soil in 3 to 6 months.Wherein oil field oil-containing mud is for through after the dehydration, and water ratio is 15%～60%, and oleaginousness be the oil field oil-containing mud less than 50000ppm, and oil field oil-containing mud is the oily sludge that dehydrates after back or the SX processing.The Ph of oil field oil-containing mud wherein is 6.5～9.The plain SG bacterium liquid of oil field oil-containing sludge degradation is Alkaliphilic bacillus (Bacillus alcalophilus).The oil field oil-containing sludge degradation of the mentioned component of the method preparation of the plain degraded of above-mentioned oil field oil-containing sludge degradation oil field oil-containing mud is plain; It can effectively be realized satisfying soil physico-chemical index and reach soil second ploughing requirement; Be the method for a kind of cost-effective processing oil field oily sludge, handle viscous crude and contain greasy filth effect cured and that colloid is high also very desirable.
Four, embodiment: embodiment 1, the plain composition of oil field oil-containing sludge degradation consists of by raw material weight per-cent: the vinasse of 0.5% SG bacterium, 1% yeast, 10% chicken manure and surplus.The method of the plain degraded of oil field oil-containing sludge degradation oil field oil-containing mud is undertaken by following step, at first SG bacterium liquid is sprayed on the vinasse trick layer culture 36 hours.Yeast powder is mixed with chicken manure again and mix thoroughly, the air dried vinasse that will spray SG bacterium liquid then mix with it to be mixed thoroughly, is oil field oil-containing sludge degradation element.Be to carry out thorough mixing at 10: 1 by volume at first with oil field oil-containing mud and degradation element; Next is stacked after 3 days and turns upside down once, and each month turns upside down once then, and the oil field oil-containing mud after 6 months promptly reaches the requirement of urban afforestation with soil.Wherein oil field oil-containing mud is for through after the dehydration, and water ratio be less than the oil field oil-containing mud of 30000ppm greater than 20000ppm in 15% oleaginousness, and oil field oil-containing mud is the oily sludge that dehydrates after back or the SX processing.The Ph of oil field oil-containing mud wherein is that Alkaliphilic bacillus (Bacillus alcalophilus) can be bought to Chinese industrial microbial strains preservation administrative center at the plain SG bacterium liquid of 6.5 described oil field oil-containing sludge degradation.
Embodiment 2: the plain composition of oil field oil-containing sludge degradation consists of by raw material weight per-cent: the vinasse of 1% SG bacterium, 3% yeast, 20% chicken manure and surplus.The method of the plain degraded of oil field oil-containing sludge degradation oil field oil-containing mud is undertaken by following step, is to carry out thorough mixing at 30: 1 by volume with oil field oil-containing mud and degradation element at first; Stack after 10 days tipping once, tipping in per then 10 days once, the oil field oil-containing mud after 6 months promptly reaches the requirement of urban afforestation with soil.Wherein oil field oil-containing mud is for through after SX and the dehydration, and water ratio is 60%, and oleaginousness be less than the oil field oil-containing mud of 30000ppm greater than 10000ppm, and oil field oil-containing mud is the oily sludge that dehydrates after back or the SX processing.The Ph of oil field oil-containing mud wherein is 9.The plain SG bacterium liquid of described oil field oil-containing sludge degradation is Alkaliphilic bacillus (Bacillus alcalophilus).
