Description
Technical field
The present invention relates to drilling well oil-sludge treatment technical field, the method for disposal of specifically a kind of toxic greasy filth of oil gas drilling and
Its product.
Background technology
Oil-containing sludge containing toxicity is will produce in oil (shale gas) drilling process, these greasy filth are bulky, do not contain only
There are petroleum resources, but also containing the harmful substance for being largely difficult to degrade.Growing tension with petroleum resources supply and environmental protection
Regulation it is further perfect, the recycling of greasy filth, harmless treatment are very necessary and urgent.According to incompletely statistics, China
The petroleum storage amount total to " 15 " end reaches 6000 × 104t, and greasy filth yield reaches (10~44) × 104t/a.These sludge
If cannot properly dispose, arbitrarily discharge will cause great damage to environment and people's life.Therefore, carry out oily sludge
Harmless treatment research, can both implement oil sludge and sand recycling, while also complying with national sustainable development policy and cycle
Economic requirement.
Due to the complex genesis of greasy filth, and greasy filth is mostly the mixture of water, mud, oil and other impurities etc., processing
It is relatively difficult.And the influence of greasy filth environmental pollution is huger, therefore the processing of greasy filth is extremely important.It is now domestic main
Processing method is strange land landfill, this is a kind of method of pollutant transfer, not only increases the destruction to environment, and also need to
Pay logistics cost.Meanwhile some processing methods include that coking technology, pyrolysis processing technology, solvent extraction technology, greasy filth are quenched
One mechanical dehydration technology, ultrasonic wave de-oiling technology, hot water wash treatment technology etc..Its device, technology, equipment etc., which require, to be compared
Height, these technologies are high, and the feature that equipment is complicated, device is advanced virtually increases the difficulty and cost of oil-sludge treatment, causes ring
Protect high cost.Moreover, during processing greasy filth, a large amount of sewage is will produce, and more harmful is had in sewage
Substance is learned, trouble is relatively responsible in the processing of these sewage.
Therefore in conclusion the prior art there are no effective methods, can be to that can be produced in oil (shale gas) drilling process
The processing of raw oil-containing sludge containing toxicity reaches innoxious, cleans and economization so that the application of resource and the contradiction of environment
Long-term existence is simultaneously increasingly sharpened.
Invention content
The purpose of the present invention is to provide a kind of methods of disposal and products thereof of the toxic greasy filth of oil gas drilling, it becomes hw08
Waste be changed into values, and the raw material as processing shale brick is tried out, and avoids pollution environment and significantly reduces processing cost, and obtains
Lower-cost shale brick, produces economic benefit.
The present invention to achieve the above object, is achieved through the following technical solutions：
A kind of method of disposal of the toxic greasy filth of oil gas drilling, includes the following steps：
1) it is 3%~8% oil shale gas to be drilled generated oil rock bits (hw08) and is carried out dehydrating to water content
Afterwards, oil rock bits powder is crushed to obtain, the sewage of abjection reaches GB18918《Urban wastewater treatment firm pollutant emission standard》Three
Grade A standards；
2) shale is crushed into obtain shale powder；
3) oil rock bits powder is mixed with shale powder, then carries out proportioning again with raw coal coal dust and mixes, obtaining calorific value is
280 card/gram raw material powder；
4) by raw material powder and oil rock consider to be worth doing deviate from sewage be mixed water content be 12~20% pug, successively
Extruded molding, pinch-off, roasting can be prepared by shale brick finished product.
The oil rock bits powder and shale powder by weight ratio 3：7 are mixed.
Above-mentioned steps are preferably：1) oil shale gas is drilled generated oil rock bits and is carried out dehydrating to water content and be
After 5%, oil rock bits powder is crushed to obtain；
2) shale is crushed into obtain shale powder；
3) oil rock bits powder is mixed with shale powder, then carries out proportioning again with raw coal coal dust and mixes, obtaining calorific value is
280 card/gram raw material powder；
4) by raw material powder and oil rock consider to be worth doing deviate from sewage be mixed water content be 18% pug, successively through squeezing
Go out molding, pinch-off, drying, roasting, firing temperature is 900 DEG C, you can shale brick finished product is made.
The prior art is compared, the beneficial effects of the present invention are：
The prior art thoroughly can not disposably solve waste sludge caused by oil drilling, especially tight to the destruction of soil
Weight.And this technology can make the oil in oiliness sludge caused by shale gas probing that construction material shale brick be added as fuel
In, one of the primary raw material as shale brick is used, and realizing turns waste into wealth.It is not only effectively protected environment, is reduced
The huge processing cost paid needed for processing greasy filth, and certain economic benefit is created, realize minimizing, the nothing of greasy filth
Evilization, cleans recycling, and the double meaning with environmental improvement and the utilization of resources provides an ideal treatment process,
With very wide application prospect.
After oil gas sludge is mixed shale by this technology, it is not only able to greatly reduce the dosage to shale, reduces adobe raw material
Materials cost.Oil rock produced by being drilled simultaneously using oil shale gas considers the abundant crude oil impurity being mingled with to be worth doing, as own combustion
Source significantly reduces raw coal dosage, economizes on resources, reduce cost instead of the production coal of part crude oil adobe.To realize
The protection of resource and the raising of economic benefit in shale brick processing.
Description of the drawings
Attached drawing 1 is that embodiment considers the analysis report list chemically examined to be worth doing to oil rock.
Attached drawing 2~4 is the survey report of brick obtained by embodiment.
Specific implementation mode
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, people in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within range defined herein.
