Description
Technical field
The present invention relates to cement mortar preparing technical field, and in particular to a kind of preparation method of high bond strength cement mortar.
Background technology
Cement mortar is the working solution used in well cementation, and the function of cement mortar is well cementation.Well cementing operation is from sleeve pipe to the borehole wall
Cement mortar is injected with the annular space of sleeve pipe and is allowed on it and returns to certain altitude, and cement mortar subsequently becomes Behavior of Hardened Cement Paste and consolidates the borehole wall and sleeve pipe
Knot gets up.
Well cementation can reach following purpose：Fixed and protection sleeve pipe：Sleeve pipe under in drilling process, it is necessary to by solid
It is fixed up by well operations.In addition, the Behavior of Hardened Cement Paste outside sleeve pipe can reduce extruding of the stratum to sleeve pipe, the work of protection sleeve pipe is played
With.Protect high-pressure oil-gas layer：When boring chance high-pressure oil-gas layer, gas blowout accident easily occurs, to improve drilling fluid density with evenly
Stressor layer, after being drilled high-pressure oil-gas layer, it is necessary to which setting of casing is cemented the well, and high-pressure oil-gas layer is protected.Insulate severe leakage layer and
Other complicated layers：When boring chance severe leakage layer, the method drilling well for reducing drilling fluid density and adding loss circulation material can be taken, is drilled
After severe leakage layer, it is also necessary to which setting of casing is cemented the well, and it is insulated, and it is not influenceed drilling well below.When boring chance, other are multiple
During diamicton, the method that can be also cemented the well after this layer is drilled with setting of casing solves.
Cement mortar is made up of water, cement, additive and extra material.The additive of cement mortar and extra material are to adjust water
Mud property, need to add some particular matters wherein, and the material that its addition is less than or equal to cement quality 5% turns into additional
Agent；Its addition is more than the material of cement quality 5%, then referred to as extra material.
In addition, also containing gypsum, alkali metal sulfates, magnesia and calcium oxide etc. in cement.These compositions, in cement
Hydration rate and cement solidification after performance, have certain influence.
As the improvement of people's living standards, also have certain requirement to road equipment, but the water of currently the majority
The defects of adhesion strength is low, fragility is high, water reducing ability is poor all be present in mud.Therefore, a kind of cement mortar pair of high bond strength is invented
Cement mortar preparing technical field has positive effect.
The content of the invention
Present invention mainly solves technical problem, have that adhesion strength is low, fragility is high, water reducing ability for current neat slurry
A kind of the defects of poor, there is provided preparation method of high bond strength cement mortar.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of preparation method of high bond strength cement mortar, it is characterised in that specifically preparation process is：
（1）Barnyard grass stalk and water mixing are weighed, pours into iron pan and boils processing, then the barnyard grass stalk taking-up after boiling, use liquid
The processing of nitrogen spray refrigeration, then the barnyard grass stalk after freezing is put into ball mill, discharged after grinding, obtain barnyard grass stalk fragment,
It is standby；
（2）Weigh after grape is rinsed with water and be put into fermentation tank, the grape in fermentation tank is smashed to pieces with without bacteria stick, obtains grape
Slurry, then dusty yeast is added into fermentation tank, after sealing and fermenting, obtain tunning；
（3）Above-mentioned tunning is filtered, isolated filtrate, filtrate and standby barnyard grass stalk fragment are mixed
After be placed again into fermentation tank, continue to be sealed by fermentation, filtered after fermentation ends, isolated filter residue；
（4）Sugar cane crushing is weighed, obtained sugar-cane juice and flour and calcium hydroxide are stirred to obtain sticky slurry,
Ceramic cylinder bottom even lays one layer of above-mentioned gained filter residue, and it is 2~4cm to control laying depth, then is uniformly put down in filter residue layer surface
The slurry of same thickness, the circulation superposition of such one layer of filter residue, one layer of slurry are spread, until final laying depth reaches 30~40cm,
Clear water is added into ceramic cylinder along the ceramic inside wall of cylinder again, until filter residue in ceramic cylinder and slurry are flooded completely, is sealed under normal temperature
Place；
（5）After above-mentioned sealing placement terminates, the self-control cement reinforcing fiber muscle slurry in ceramic cylinder is taken out, is counted in parts by weight,
Weigh 60~70 parts of Portland cements, the Ludox that 10~20 parts of mass fractions are 10%, 10~20 parts of self-control cement enhancings
Fiber bar is starched to be fitted into cement mixer with after 20~30 parts of water mixing, is discharged after being stirred, is produced high bond strength cement
Slurry.
Step（1）Described in barnyard grass stalk and water mass ratio be 1:10, it is 2~3h to boil processing time, and liquid nitrogen sprays
The leaching freezing processing time is 2~3min, and milling time is 30~40min.
Step（2）Described in time of smashing to pieces be 15~20min, the addition of dusty yeast is the 1% of grape slurry quality, close
The temperature of seal ferment is 26~28 DEG C, and the time of sealing and fermenting is 12~14 days.
Step（3）Described in filtrate and barnyard grass stalk fragment mass ratio be 5:1, the temperature of sealing and fermenting is 35~40
DEG C, it is sealed by fermentation 15~20h.
Step（4）Described in normal temperature under seal placement number of days be 25~30 days.
Step（5）Described in the rotating speed being stirred be 60~70r/min, the time being stirred is 5~10min.
The beneficial effects of the invention are as follows：
（1）The present invention does harm to weeds barnyard grass as raw material using agriculture, realizes twice laid first, barnyard grass is boiled with boiling, through overheat
Power effect improves the plasticity of barnyard grass fiber, makes tentatively to dissociate between its fiber, then by liquid nitrogen frozen, is split and acted on into one using ice
Step dissociation, coordinates ball-milling treatment to obtain barnyard grass fibre bundle, is obtained afterwards using grape fermentation rich in amino, carboxyl isoreactivity group
With the zymotic fluid of grape wine, zymotic fluid and the blending fermentation of barnyard grass fibre bundle are carried out at hydroxylating using grape wine to fibre bundle
Reason, and active group is incorporated into fibre bundle surface in the presence of microorganism, improve fibre bundle surface hydroxyl and active group
Quantity, the polyhydroxy characteristic of the starch added using fibre bundle and later stage, make cement granules can be with dispersed absorption at both
Surface, prevent cement from reuniting, reduce unit consumption of water, reach the purpose for improving cement water reducing ability；
（2）It is fine that barnyard grass fibre bundle and sugar-cane juice, flour mixed fermentation are also obtained sticky greatly self-control cement enhancing by the present invention
Tie up muscle slurry, then self-control cement reinforcing fiber muscle slurry and cement, Ludox and water are mixed, obtain with plasticity and close-burning
Cement mortar, the hydroxyl that the abundant active group in surface and cement particle surface are starched by making cement reinforcing fiber muscle by oneself produce hydrogen bond
Attraction and Chemical bonding, the bond strength of cement mortar is greatly improved, play a part of thickening and strengthen, and fiber bar is starched
The toughness and mechanical performance of itself are splendid, and globality is strong after grout cures, not easy to crack, and fragility is improved, and have wide
Application prospect.
