Description
Technical field
The present invention relates to soft starter technical field, particularly relate to the processing method of a kind of well drilling waste mud.
Background technology
Well drilling waste mud is the mixture that the discarded solid-liquid produced in the drilling process of oil gas field well site is formed.
Mainly by drilling fluid, landwaste, completion fluid, flushing fluid, well killing fluid, fracturing fluid and produce in drilling process
The material compositions such as raw waste water.Containing the most toxic, the material of difficult degradation in this mud.If without
Process directly discharge, it will the soil near pollution, water source, and finally jeopardize health.
This is mainly reflected in the following aspects:
High salt the most therein and high ph-values inorganic agent can cause soil compaction, make the degree of the salinization of soil of soil add
Deeply；
The heavy metal ion the most therein enrichment by food chain, causes poison to the human body on food chain top
Evil effect；
3. the fragrant footpath in oil and polycyclic aromatic hydrocarbons are to be difficult to by the carcinogen of natural degradation；
4. the polyacrylamide compounds in mud and derivant thereof have nerve intoxicating effect；
5. crude oil has a strong impact on loam permeability the pervious function of the soil layer by the soil of crude oil pollution is declined,
Become relative water resisting layer.
Various harmful substances cannot natural degradation, cause underground and water source is long-term severe contamination.
The land resource being contaminated cannot growing plant, can not farming.The water source being contaminated can long-term hazards exist
The health of the people lived about.So the long term growth from the probing of oil gas field with production industry considers, must
Must take effective processing method that the discarded slurry produced in drilling operation course is carried out degradation treatment.
In the case of oxygen abundance, microorganism is can be complete by organic pollutant degradation by Oxidation, point
Solution becomes inorganic matter (such as CO2、H2O、NO2-、NO3-、SO4 2-、PO4 3-Deng).In the case of oxygen-deficient,
By anaerobic respiration effect, larger molecular organics can be degraded into small-molecule substance.Organic substance is main in environment
Pollutant component, first the control of environmental pollution seeks to organic matter degradation therein is become nonhazardous effect
Material.The high treatment capacity of organic pollution is played key effect in biological restoration by microorganism.
Heavy metal is as the high pollutant of a kind of toxicity, it has also become a significant problem in environmental pollution, research
Oneself confirms that it creates serious negative effect to biological existence, therefore finds and removes the side of heavy metal in environment
Method has become the focus of current Research of Environmental Sciences.
Summary of the invention
It is an object of the invention to provide the processing method of a kind of well drilling waste mud, through microorganism-cured
Combined Treatment technology effectively removes the content of organics in waste liquid mud, reduces because Organic substance is substantial amounts of
Depositing, water content reduces, and greatly reduces the pollution to environment.
To achieve these goals, present invention employs following technical scheme: a kind of well drilling waste mud
Processing method, comprises the following steps:
(1) microbial treatments
A. detoxification: noxious substance in waste mud is converted into nontoxic or that toxicity is relatively low material by microorganism or its enzyme system
Effect or process；
B. degumming: utilize the enzyme that fermentable effect produces, enzyme makes colloid decompose, and reaches waste mud degumming
Purpose；
C. desalination: during microbial degradation is organic, can produce electronics, forms voltage, makes sodium ion
Separate with chloride ion, thus reach desalination purpose；
D. dehydration: utilize microorganism to change the water storage structure formed in waste mud, by the absorption water being difficult to remove,
Capillary water transfers the gravitational water to remove to, reaches to be dehydrated purpose；
(2) cured
The waste mud crossed through microbial treatments carries out cured, and cured uses firming agent so that it is
There is a series of physics and chemical reaction with pollutant thus form the induration with some strength.
The beneficial effects of the present invention is: after using said method, main hydrocarbon in discarded slurry
Having obtained degrading significantly, metal ion has obtained converting significantly, and the physical behavior of mud obtains
To repairing significantly, as occurred expanding and crack performance after breaking gel, moisture content reduces, during PH returns back to
Property, through microorganism-solidification method Combined Treatment technology, substantially reduce drilling waste mud environmental pollution can
Energy property, solves waste drilling mud recycling and drilling mud problem of environmental pollution well.

Capillary water transfers the gravitational water to remove to, reaches to be dehydrated purpose；
(2) cured
The waste mud crossed through microbial treatments carries out cured, and cured uses firming agent so that it is
There is a series of physics and chemical reaction with pollutant thus form the induration with some strength, afterwards
Can be using landfill disposal or as construction material etc..
Microbial treatments are the feature according to discarded slurry and existence, therefrom filter out the micro-life of efficient degradation
Thing, sets up the strain combinations of biosurfactant, is then added in waste drilling mud, adjusts micro-
Biological agent environment, such as temperature, nutrient, pH value, salinity etc..Some areas are affected by environmental factors,
Biodegradation rate is slow, by improving temperature, applying nutrient, inoculate the methods such as obligate antibacterial and promote biology
Degraded so that it is detoxification, degumming, desalination, dehydration, reaches the purpose that harmless biological processes.
