Description
Technical field
The present invention relates to the petroleum drilling technology field, particularly the drilling well solid waste recycling treatment is that a kind of drilling well solid waste is made non-burning brick jointing compound.
Background technology
At present, drilling well solid waste mainly comprises drilling waste mud and well drilling detritus.Drilling waste mud is the big stable gel system of water cut, mainly is made up of wilkinite, tiff and mud conditioner etc., and other also is mixed with a small amount of landwaste and additive is used in drilling well, and general water ratio is about 90%, and wilkinite accounts for 5%.Well drilling detritus is mainly the earth cuttings that drilling process produces.
The non-burning brick technology of drilling well solid waste to the research of drilling well solid waste comprehensive utilization technique.Contain native low, the ground barium sulfate content height of measuring because drilling mud has, add the reinforcing raw material of an amount of coarse aggregate, under the high pressure effect, form high strength monolithic, the pollutent of drilling well solid waste is solidified in the brick body through tackiness agent as slurry bricks.
The non-burning brick relevant criterion that can reach national building trade that the drilling well solid refuse is made, utilization of waste material is the treatment measures that meet current national environmental protection energy saving policy on material of construction.Well station under the Southwest Oil, the geographical position is main with the mountain area, hills, the non-burning brick of drilling well solid refuse making can effectively be utilized in the well site surface construction, has certain economic and social benefit.
Be entitled as in the patented material of " a kind of non-burning brick and working method of utilizing oil field sludge to process " CN1526529; Adopt and add solidifying agent, river sand, cement, flyash, water, the pressure that on pressing machine, imposes 500-700KN is processed type, the demoulding; Drying is processed finished product.Utilize the C in the cement
2S, C
3The hydration that mineral substance such as S take place forms hydrated calcium silicate, relies on the stable cement structure of the auxiliary formation of solidifying agent.But drilling well solid waste through add cement as jointing compound make non-burning brick.Because drilling waste mud is the very big stable gel system of water cut, behind the interpolation ordinary Portland cement system slurry bricks, be difficult for maintenance, hydration reaction is inhomogeneous in the drilling well discarded slurry body, and local moisture loss is fast, occurs crackle easily; Brick body fragility is higher, and intensity is influenced; The part that greasy dirt is heavier, brick body easy deformation in the maintenance processes, yield rate is lower; Simultaneously with cement as tackiness agent, increased material consumption quantity, increased cost.
Summary of the invention
The objective of the invention is: a kind of drilling well solid refuse making burn-free bricks jointing compound is provided, non-burning brick crackle, distortion, intensity is low, cost the is high problem of being easy to generate of making that a kind of drilling well solid waste makes that non-burning brick jointing compound overcomes that drilling well solid waste manufactures.And the non-burning brick ultimate compression strength of preparation reaches common brick MU10 standard, soaks water quality and reaches the national sewage comprehensive emission standard primary standard.
The technical scheme that the present invention adopts is: bonding agent of baking-free bricks prepared from drilling well solid waste materials is characterized in that: the weight part of each component is respectively: 3.3～8 parts of Poly aluminum Chloride (PAC)s; 6～25 parts of phosphogypsums; 10～26 parts of unslaked limes; 20～60 parts in flyash; 4.4～12 parts in ferrous sulfate.The raw material that is adopted is the solid technical grade.With each component mixing and stirring, obtain bonding agent of baking-free bricks prepared from drilling well solid waste materials.
With the above-mentioned compsn mixed preparing together, be referred to as bonding agent of baking-free bricks prepared from drilling well solid waste materials.
Each ingredients weight parts of making burn-free bricks is: 10～22 parts of bonding agent of baking-free bricks prepared from drilling well solid waste materials; 30～55 parts of drilling well solid wastes; 35～45 parts of coarse aggregates mix each component, and through the baking-free brick-making machine extrusion molding, maintenance 14～21 days is processed non-burning brick.The non-burning brick ultimate compression strength that this agent is made can reach common brick MU10 standard, soaks water quality and reaches the national sewage comprehensive emission standard primary standard.Those skilled in the art know non-burning brick maintenance, are not described in detail.
Coarse aggregate comprises useless brick bits, slag, metallurgical slag, coal gangue, mine tailing, river sand or the land waste of particle diameter at 4.75～9.75mm.
For the effect of Poly aluminum Chloride (PAC) at drilling well solid refuse making burn-free bricks jointing compound, Poly aluminum Chloride (PAC) is lower-cost inorganic flocculating agent, has absorption preferably and takes off steady effect; Colloidal particle and suspended substance surface electric charge in the absorption drilling well solid refuse; Reduce Zeta potential, colloidal particle has been become mutually by original repelling each other inhale, destroyed the stability of micelle; Impel colloidal particle to collide each other; Thereby form cotton-shaped coagulating sedimentation, polymer greasy dirt and chemicaladditives can fully be wrapped in the brick body particulate crystal, reduce the leaching of pollutent; Simultaneously the moisture content in the drilling well solid waste is fully separated out, can participate in the aquation reflection, make the brick body of making be difficult for be full of cracks.
The unslaked lime that adds has been regulated the useless admittedly Ph value of drilling well simultaneously, under neutrality-weakly alkaline environment, can better bring into play the flocculating effect of Poly aluminum Chloride (PAC).Ca ion in the unslaked lime raising system simultaneously of adding, thereby the activation efficiency of raising flyash.
Itself does not have gelling property flyash, under normal temperature, normal pressure and when having water to exist, the active ingredient in its contained a large amount of aluminate glass body, have can with Ca (OH)
2Pozzolanic reaction takes place, and generates the gum material with intensity.Excite the active gelling property of flyash through chemical activator, select for use phosphogypsum and ferrous sulfate can play the effect of flyash stimulator preferably.
The present invention excites the gelling property of flyash through the method for adding phosphogypsum, ferrous sulfate, unslaked lime employing chemical activation, and in making non-burning brick process, through the mechanical presses of high pressure, it is long-pending to increase the particle surface in contact, to accelerate hydration reaction speed; The ettringite crystal that reaction generates is under the HS impressed pressure; It is more little that the crystalline structure hole becomes, and intensity is high more, and the existence of ettringite has reduced the void content that the moisture content in the drilling well solid waste is had a surplus and participated in the aquation reflection and produce; Reduced the mean pore size in the brick body; Strengthen the contact surface of aquation calcium sulphoaluminate and aquation sulphur calcium ferrite gel simultaneously, reach the increase brick strength, prevent the purpose of brick body deformability.
Beneficial effect of the present invention: bonding agent of baking-free bricks prepared from drilling well solid waste materials of the present invention; Can prepare non-burning brick; Through non-burning brick sampling and do immersion experiment; By " industrial solid wastes leaching toxicity test method standard " sampling and immersion process (GB5086), get the leach liquor analysis, analysis draws each item pollutent index and all reaches " integrated wastewater discharge standard " primary standard (GB8978-1996).Through the check authentication of building material product quality supervision and test center, Sichuan Province.According to the JC422-1991 standard test, this sample institute inspection project reaches standard-required, and it is qualified that this sample institute inspection project is judged to.
