The using method comprises the following steps: adopting hardener according to 5-40 percent weight in the solidified mud; blending hardener in the solidified mud completely; stirring for 3-10 min; making mud lose fluidity; stewing for 24 h-7 days to solidify the mud; adding 3-14 percent solidified mud in the sand or broken stone firstly.
Description
One, technical field: the present invention relates to a kind of solidifying agent and using method thereof, solidifying agent that particularly a kind of mud that is used for waste drilling is cured and its using method.
Two, background technology: the petroleum drilling exploitation must be used mud, because in use all kinds of geological stratifications are to the physical chemistry infringement of mud, and spontaneous a series of physics such as oxidation-reduction, variations such as chemistry and colloid segregation, cause mud aging and can't continue to use, and be forced to discard, the maximum characteristics of drilling mud are concretenesses not, and contain the chemical ingredientss that exist in a large number with ionic species, the directly discharging if do not carry out harmless treatment, through erosion, flow, soak into, osmotic potential must cause substantial pollution to environment, destroy the eubiosis,, just must carry out harmless treatment it in order to keep harmonious ecotope.
The main method of handling mud at present has: hold with regard to melt pit and deposit, bury, also some building cementing materials such as useful a large amount of silicate cements are cured processing, this method weak point bad adaptability of filling a prescription exactly, the numerous and diverse constructional difficulties of technology, because of the mud difference, exist and can not solidify for a long time, not water-fast, drenched erosion by rainwater, still caused secondary pollution problem.
Three, summary of the invention:
1, goal of the invention: the invention provides a kind of curing agent for waste drilling mud and using method thereof, its objective is and solve the direct exhaust emission environment of waste drilling mud, bad with building cementing material curing discarded slurry effect, the problem that does not have a kind of aspects such as solidifying agent that well are used for waste drilling mud to exist now.
2, technical scheme: the present invention is achieved through the following technical solutions:

Each metal in the above-mentioned raw materials or the fineness of nonmetal oxide are more than 8 μ m, and screen over-size is less than below 5%.
A kind of using method of curing agent for waste drilling mud, it is characterized in that: by 5～40% weighting profit requirements, the 1 described solidifying agent of institute's solidified slip gross weight, solidifying agent added want in the solidified mud behind the thorough mixing, after stirring 3～10 minutes mud and losing flowability, place after 24 hours～7 days, mud is promptly curable.
In mud, add sand or rubble earlier by 3～14% of institute's solidified slip weight.
3, advantage and effect: by the enforcement of technical solution of the present invention, can solve the direct exhaust emission environment of waste drilling mud well, bad with building cementing material curing discarded slurry effect, the problem that does not have a kind of aspects such as solidifying agent that well are used for waste drilling mud to exist now.Slurry curing agent of the present invention is suitable for various water-based mud, oil-base mud, want to make slurry curing, only need add solidifying agent in the mud by different ratios and stir according to different demands, discarded slurry just loses flowability in very short time, then form anti-water body stable, that have certain intensity, thereby the volatilization, diffusion, the loss that define the harmful chemical component in the mud are soaked into.And reach the protection environment purpose.
Solidifying agent of the present invention is easy to use, and is simple to operate, only needs press to stir in 5～40% adding mud of the curable phase of mud to get final product, quick solidifying, can artificially control set time, adjusts, maximum characteristics are that this solidifying agent adaptability is strong, and extensively, cost is low, solidification intensity is strong, consolidation strength in 24 hours is not less than 45Kpa, and consolidation strength reached 3Mpa in 7 days, reached as high as 7.5Mpa, and anti-water, immersion is not split not loose in the long-term water.
In mud, add sand or rubble when solidifying agent uses by a certain percentage, accelerated curing speed, also guaranteed solidification effect, make the mud piece after the curing possess good intensity simultaneously.
Four, embodiment:
The present invention is to be oxygenant with CaO, SiO

3～1.58 * 10
4Doubly
Solidify the physical and chemical parameter of back mud:
Dash and release water oleaginousness: 0.18～5.2mg/l
Chemical oxygen demand: 24.3～140mg/l
Chrome content: 0.007～0.009mg/l
Free phenol: 0.08～0.1mg/l
Colourity: 14～29 times
The physics contrast:
Before the curing: indefinite form is soluble in water and run off, and has the infiltration wetting property.
Solidify the back: when solidifying in 24 hours, withstand voltage reaches 45KPa from 4KPa, and after solidifying 24 hours, its withstand voltage reaches more than the 45KPa, solidifies after 7 days, and its withstand voltage maximum can reach 7.5MPa; Long-term immersion is not loose, not softening, impermeable, do not soak into.
