Abstract

The treatment method of oil field drilling waste mud water includes: using strong oxidant to degrade macromolecular organic compound and oil-like substance being in the waste mud water and convert them into small molecular weight compound, then adding demulsifier to make demulsification, adding flocculant to make flocculation, adopting settling or air-floating process to remove flocculate and obtain clear liquor, filtering said clear liquor and making it undergo the process of adsorption treatment to remove residual oil-like substance, finally introducing the filtrate into reactor and reacting with ammonia water or liquid ammonia to synthesize said invented fertilizer. Said invention can be extensively used for treating waste mud water in the oil field.

Description

A kind of improvement method of waste mud-slurry of oil-field well-drilling
The present invention relates to a kind of improvement method of waste mud-slurry of oil-field well-drilling
At present oil may visit with the oil drilling oil recovery process in, must add the slime water of composition complexity during drilling well, run well to guarantee drill bit, and overflow waste mud-slurry simultaneously.The Chemical Composition of these waste mud-slurries is very complicated, not only contains macromolecule organic, but also contains kerosene. diesel oil. and the oily substance of machine oil class, the more serious high-concentration chlorine ion that is difficult to remove that also contains, its content is up to 200,000 PPm.Also less than chlorion removal methods in the high salt waste mud-slurry of oil drilling, there is not the improvement method of waste mud-slurry of oil-field well-drilling at present yet.High salt of these undressed oil drillings or less salt waste mud-slurry jeopardize the growth of farm crop on every side, even make animal dead, destroy the eubiosis, must thoroughly administer.
The improvement method that the purpose of this invention is to provide a kind of waste mud-slurry of oil-field well-drilling.It can administer high salt of oil drilling or less salt waste mud-slurry.
In order to achieve the above object, the improvement method of a kind of waste mud-slurry of oil-field well-drilling of the present invention is characterized in that adopting the following step:
The waste mud-slurry that overflows during (1) with oil drilling carries out solid-liquid separation and obtains waste water;
(2) in waste water, add strong oxidizer gas, thereby macromolecule organic in the degrading waste water and oily substance become the chemical substance of small molecular weight;
(3) adding soluble calcium salt or magnesium salts carries out breakdown of emulsion and transfers pH value to alkalescence with milk of lime;
(4) add polymerize aluminum chloride or polymerization iron aluminium and micro-polyacrylamide behind the breakdown of emulsion, generate a large amount of flosss behind the stirring reaction;
(5) adopt sedimentation method or air-float method to remove floss and obtain clear liquid;
(6) clear liquid is removed remaining oily substance through sand bed and diatomite filtration, absorption and obtain filtered liquid;
(7) filtered liquid is placed in the reactor, add ammoniacal liquor or liquefied ammonia, stirring reaction is combined to liquid nitrogen fertilizer.
Described strong oxidizer is a pure chlorine dioxide, and working concentration is 20~100PPm.
When oil drilling overflowed high salt waste mud-slurry, described ammonia concn was 10~20%, and consumption is 2~3.5 times of chloride ion content in the filtered liquid; Described liquefied ammonia consumption is 0.1~0.3 times of chloride ion content in the filtered liquid.
When oil drilling overflows the less salt waste mud-slurry, can save step (7), need not to add ammoniacal liquor or liquefied ammonia chemical combination.
Adopt above-mentioned improvement method, become small molecular weight compounds with strong oxidizer degraded macromolecular organic compound and oils thing wherein, use the emulsion splitter breakdown of emulsion then, adding flocculation agent again flocculates, remove floss with sedimentation or air-float method again and obtain clear liquid, the clear liquid Filtration Adsorption is removed remaining oily substance, filtered liquid is introduced in the reactor at last and be combined to fertilizer with ammoniacal liquor or liquefied ammonia.Have nontoxic, effective, environment is not produced the advantage that pollution, cost are low, turn waste into wealth, reach zero emission, can be widely used in oil and may visit improvement with oil drilling oil recovery waste mud-slurry, be particularly useful for the improvement of the high salt waste mud-slurry of oil drilling.
Below in conjunction with drawings and Examples to the present invention's detailed explanation of making comparisons.
Fig. 1 is the skeleton diagram of the improvement method of the high salt waste mud-slurry of a kind of oil drilling of the present invention.
Fig. 2 is the skeleton diagram of the improvement method of a kind of oil drilling less salt of the present invention waste mud-slurry.
Embodiment one
The improvement method of the high salt waste mud-slurry of a kind of oil drilling shown in Figure 1 is adopted and is: after the high salt waste mud-slurry that at first oil drilling is overflowed separates solid phase (being mud) with the method that leaves standstill, can obtain the opaque high-salt wastewater of oyster white, the visible one deck oily substance in surface, can smell strong machine oil, diesel odor, after measured its PH=7, COD=1270mg/L; With the pure chlorine dioxide of dioxy chlorine generator generation, concentration is that 20~80ppm feeds in the high-salt wastewater, because of pure chlorine dioxide is a strong oxidizer, makes macromolecule organic and oils deposits yields oxygen in the high-salt wastewater, generates the chemical substance of small molecular weight then; Add 0.2%~1% soluble calcium salt or magnesium salts again, stir the companion and carry out breakdown of emulsion after 0.5~1 hour and transfer pH value to meta-alkalescence with milk of lime; Add 0.03%~0.1% polymerize aluminum chloride or 0.03%~0.1% polymerization iron aluminium again, stir 5~15 minutes afterreactions and generate a large amount of flocculent precipitates; Disgorging can obtain supernatant liquor after the sedimentation of swash plate pond again; Again supernatant liquor is removed wherein remaining oily substance through sand bed and diatomite filtration absorption, obtain about PH=7, about COD=81mg/L, the water white transparency filtered liquid about oils thing 15mg/L, other index all reaches discharging standards except that chloride ion content; To place in the reactor of a band stirring through the filtered liquid after above-mentioned materialization is handled at last, adding concentration is 10~20% ammoniacal liquor, add high-volume 2~3.5 times for chloride ion content, or adding liquefied ammonia, consumption is 0.1~0.3 times of chloride ion content, stirs half an hour, chlorion in the filtered liquid and ammoniacal liquor or liquefied ammonia are combined to ammonia chloride, promptly become the needed a kind of nitrogenous fertilizer of plant, this liquid fertilizer is nontoxic, and environment is not produced pollution.
Embodiment two
A kind of as shown in Figure 2 improvement method of oil drilling less salt waste mud-slurry is the last chemical combination step of cancellation, the filtered liquid of promptly cancelling after embodiment one will handle through materialization at last places the step that generates nitrogen in the reactor with ammoniacal liquor or liquefied ammonia reaction, because chlorion seldom in the filtered liquid that oil drilling less salt waste mud-slurry obtains after handling through above-mentioned materialization, all index all reaches discharging standards, can directly discharge.All the other partly with
Embodiment one is identical.
