Cycling and reutilization etc..More research has been done in domestic and international processing of the oil gas field industry to well drilling waste mud, and China uses at present
Processing well drilling waste mud method is main or curing process method, prepared by microbiological treatment technology, drilling mud unburned
Brick technology and well drilling waste mud are also more ripe with the research for boring treatment technology, but not yet large-scale application.
Solidification backfill processing method, it is to isolate discarded slurry by the de- steady, flocculation of chemical treatment, separation of solid and liquid
Sewage discharges after after-treatment reaches national standard；The solid formation of solid-liquid separation reinforces agent and carries out curing process, is surveyed after processing
Filled after leachate is up to standard.The processing mode of solidification landfill drilling wastes gradually exposes many problem and shortage：It is first, solid
Change method is follow-up disposal or synthesis because the addition of a large amount of curing agent, final solid waste amount add 30% on the basis of original
Using bringing very big difficulty；Second, environmental risk after solidification landfill still be present, pollutant is simply fixed on solidifying pool by solidification
It is interior, not polluter resolution is fallen, in the long term, once harmful substance changes in firming body, outwardly revealed, it is right
Certain pollution risk be present in environment.In order to eliminate pollution, environmental protection, turn waste into wealth, well drilling waste mud management increasingly to
Innoxious, recycling direction is developed.
Since thousands of years, the clay brick construction material most widely used as maximum plays in human lives and production
The effect that can not be estimated.Although various New Building Materials continue to bring out in recent years, clay brick is still that China is main at present
Materials for wall.But this development is largely with the breaking-up in cultivable soil, and the non-renewable energy is excessive
Consumption and environmental pollution are cost.Because the arable land of fired clay brick breaking-up is up to more than 150,000 hectares, clay is produced every year
The coal consumption of brick is about 70,000,000 tons, SO2Annual emissions be 980,000 tons, CO2Annual emissions be 1,560,000 tons, they turn into big
One of major pollutants in gas.The above mentioned problem that clay brick is brought, it is the major issue for being related to national economy.Therefore, find
The replacement building materials of clay brick or new materials for wall, which are one, can not hold slow research topic.
The content of the invention

Clay；The pollutant catabolic gene agent is river sand, stone or cinder.
Further, the cement is the cement marked as No. 32.5 or No. 42.5；The activity excitant is made a living stone
Ash, white lime and calcium hydroxide；It has been investigated that quick lime can reach preferable activation effect as activator, with quick lime system
Standby non-burning brick compression strength is up to more than 15Mpa, higher than white lime and calcium hydroxide（About 13MPa）.The retarder is preferred
For alpha-semi water plaster stone；Gypsum can reach more than 10MPa, wherein α-half as non-burning brick compression strength prepared by retarder
Water gypsum intensity highest, its non-burning brick compression strength reaches more than 13.4Mpa, better than gypsum and β-semi-hydrated gypsum；The silica
Compound is preferably silica.
Further, the non-burning brick intensity that above-mentioned three kinds of pollutant catabolic gene agent are prepared under the same conditions is different, wherein river
It is husky（Fine sand）, stone（Coarse sand）Experiment effect is close, and non-burning brick effect prepared by clinker is poor, specifically used any, can
Determined according to locality materials.Both compounds can be selected, but both be better than the effect of clinker.From river sand（Carefully
It is husky）, stone（Coarse sand）Difference is little.
Further, the raw material components also include other auxiliary agents 0-3 parts, and other described auxiliary agents are early strength agent, water reducer
And one or several kinds of combinations in gel breaker；The early strength agent is preferably sodium chloride or calcium chloride；The water reducer is excellent
Elect calcium lignosulfonate as；The gel breaker is preferably aluminium salt or molysite.
Further, the drilling cuttings, cementing agent, activity activator, retarder, pollutant catabolic gene agent, reinforcing agent and its
His auxiliary agent quality is 52 than Optimal Control：28：10：3：5：3：1.By to cement, activator, pollutant catabolic gene agent, reinforcing agent
Dosage research is found, with the increase of cement, activator, pollutant catabolic gene agent dosage, non-burning brick compression strength is presented and gradually risen
Trend, wherein drilling cuttings/cementing agent/activator/retarder/pollutant catabolic gene agent/reinforcing agent/other auxiliary agent mass percents are
52/28/10/3/5/3/1 reaches compared with the figure of merit.
The preparation method of above-mentioned discarded slurry making burn-free bricks given below, comprises the following steps：
（1）Discarded slurry progress pre-treatment step is obtained into drilling cuttings, the pre-treatment step includes drying, crush and sieving；
（2）Part cementing agent, activity excitant, retarder, reinforcing agent, pollutant catabolic gene are selectively added into the drilling cuttings
Agent and other auxiliary agents, after being well mixed plus water wheels grind, and clinker is made after ageing process；
（3）Secondary into the clinker to add remaining cementing agent and water, abundant rolling obtains batch mixing again；
（4）The batch mixing is put into mould it is compressing through moulding process, the demoulding obtain adobe；
（5）The adobe spontaneously dries after maintaining process and obtains finished product.
The cementing agent can also be in step（3）In disposably add；That is step（2）In be added without cementing agent.
Further, pretreatment if necessary can to discarded slurry add gel breaker, be then dried successively, crush with
And sieving.

Compressive Strength keeps stable.Because requirement of the meticulous raw material to disintegrating apparatus is high, drilling cuttings is crushed to so can contemplate during production
0.3-0.6mm, equipment requirement can be so reduced, can also reach an of a relatively high compression strength value.
Further, the step（2）And（3）The cementing agent of addition is cement.
Further, the step（2）In ageing process at normal temperatures place 2-12 hours；Batch mixing adds water to stir
Afterwards, the complete aquation of auxiliary material cement, activator needs a period of time, that is, is aged, repressurization shaping.Effect is aged with digestion time
Increase first strengthens to be weakened afterwards, and Best Times are 8 hours or so.
Further, the step（3）The moisture control of middle batch mixing is 5%-15%；The moisture content of batch mixing for test specimen most
Compression strength afterwards plays an important role, aqueous too low, and the curing materials aquation such as cement, activator is insufficient, and raw material utilizes
Rate is low, influences intensity；It is aqueous too high, substantial amounts of water outflow is had in extrusion forming, the test specimen demoulding is easy defect, is both influenceed
Forming operation, cause that test specimen is imperfect again, so aqueous should control, raw material can abundant aquation, be unlikely to overly moist again, influence
Shaping.Measuring of moisture content is 5%-15% in this experiment, as a result, intensity is presented one and first rises then downward trend, optimal
Moisture content be about 13%.
Further, the moulding process is：Batch mixing is fitted into steel die, is press-formed on pressure testing machine,
Pressing speed control is molded in 0.5-1KN/s, or manual pressure, briquetting pressure 15-60MPa.Referring to Fig. 2, institute is press-formed
Obtain its non-burning brick compression strength and be much larger than pouring molding, and the compression strength increases with the increase of briquetting pressure, this is due to
Hypotony can make it that product compactness is inadequate, not only influence resistance to compression, rupture strength, also not resistant to corrosion, may result in drilling cuttings
In organic pollution leakage, polluted-water.When briquetting pressure declines on the contrary more than 60MPa, compression strength, this is due to excessive
Pressure the moisture in raw material is discharged by excessive compression, be unfavorable for the further hydration mistake of cement, activator, reinforcing agent on the contrary
Journey.Excessive in view of pressure, the infringement to experimental facilities, and pressure are excessive also so that moisture is completely expressed in test specimen, no
Beneficial to further hydration process.Pressure general control is in 15-60Mpa.Actual production process can be according to each side such as equipment situations
Noodles part, appropriate adjustment.
Further, the step（5）In maintaining process be：Adobe is placed at shady and cool ventilation and spontaneously dried, then
Appropriate watering ensures the abundant aquation of raw material, so maintenance 7-35 days.Natural curing is used, adobe is placed on ventilation and no longer
Mobile, after a few hours, adobe surface is gradually dried, and can be sprinkled water in right amount, ensures the abundant aquation of raw material, but is unlikely to overly moist, water
Content general control in 5-15%, after said process conserves 7-35 days brick can stacking, then spontaneously dry to detecting.
The non-burning brick of the inventive method preparation has higher resistance to compression and rupture strength, and compression strength is not less than 11MPa, resists
Folding intensity is not less than 2MPa, and compression strength can reach 12.8MPa, and rupture strength can reach 2.8MPa, its leachate
Indices reach《General industrial solid waste storage, disposal site contamination control standard》（GB18599-2001）, and cost
It is relatively low；The discarded drill cuttings of drilling well, which prepare baking-free brick technology, can not only eliminate influence of the well drilling waste mud to environment, moreover it is possible to
Prepare it is non-burning brick be used to pave the way, build well site enclosure wall, living area, cost is built in reduction, has certain economic benefit.In nothing
Evilization also achieves the recycling to drilling waste mud while improvement.In addition, it is originally used for filling the rock of discarded slurry
Bits pond can also remove, and Economization on land, reduce leased land, alleviate land used anxiety problem.
Comprehensive utilization is the important industry policy of country, and novel wall material is produced using cement and drill cuttings（Such as system
Make non-burning brick）, can not only economize the land resource, save the energy, largely digest drill cuttings, drilling cuttings is obtained preferable profit
With, while can sweep for the sustainable development of petroleum industry with environment purification and find new increase income a little；On the other hand clay will also be overcome
The in straitened circumstances problem that brick production is faced, does one's bit for the materials for wall in China.So drill cuttings prepare novel wall material
