Description
Technical field
The present invention relates to a kind of pile foundation breast wall mud materials, specifically a kind of efficient instant mud powder and preparation method thereof.
Background technology
It is to ensure large quantities of new construction high-quality and low wind in the infrastructure constructions such as growing railway, subway
Danger construction, rotary digging drilling hole construction technology is because with the technical advantage such as working security is high, environmental effect is little and construction quality is high
It is widely used.Rotary drilling rig is generally static mud protecting wall when constructing, and is formulated by bentonite or single thickener component more,
There are need during slurrying artificial many in technological layer, it is big to abandon slurry amount, abandon that slurry is untreated easily to form secondary public hazards, abandon slurry
What is processed is costly, slurrying high cost and the drawback such as pollution environment is serious, it is impossible to meet high-quality, low-risk, environmental friendliness and
The demand of civilized construction.Polymer mud is a kind of artificial-synthetic copolymer of high molecular, and it can be in relatively low concentration bar
Under part, splendid viscosity environment is created.Its extremely long strand disorderly disperses in mud in web-like, and these single rouleaus are received
Will extend to after shearing force, through different aspects cross structure is formed, this surface adsorption acts on drilling with bridge joint
When can doing the trick, it is ensured that surrounding formation is stablized；Meanwhile, this effect can also help mud cohere to greatest extent by
Drilling cuttings under cutting so that drill bit can remove easily drilling cuttings from drilling, so as to improve drilling efficiency.Polymer mud so that
With it is convenient, abandon little little slurry amount, environmental pollution and secondary public hazards, slurrying when using artificial few advantage, in rotary digging drilling hole construction
Just it is widely used.
There are fluid loss height, the problem that viscosity is low, retaining wall effect is general country's drilling well polymer mud more at present, and following
Ring is utilized and the use of complex geological condition above still suffers from defect.These all easily cause it is artificial it is many, abandon slurry amount greatly, high cost.
A kind of preparation method of drilling mud shaking is disclosed in CN105482789A, in mud prepared by the method bentonite is contained,
Making the water-retaining property and retaining wall power of mud strengthens, but it is unresolved abandon the subject matters such as slurry amount is big and environmental pollution is serious, do not consider
To the bentonite component of the abandoning tradition in Slurry confection, and can still reach the product of same retaining wall effect；
A kind of preparation method of Rock and Soil Drilling borehole engineering polymers type unfixed phase slurry, the mud product are disclosed in CN102994060A
Only in loose sand and detrition rock stratum, be suitable for that geological conditions is single, and do not refer to mud recycle this effect；
A kind of preparation method for the treatment of agent of drilling mud is disclosed in CN104312553A, the mud product component is single, function only office
It is limited to the anti-collapse retaining wall of mud stone, is not improved in environmental protection, recycling and in terms of being suitable for various geological conditions.This
A little products only stress the lifting to a certain performance of mud, it is impossible to meet the rotary digging wellbore construction on various stratum comprehensively to mud
The requirement of energy.For Various Complex geology such as layer of sand, clay layer and water-sensitive geology, it is desirable to the anti-collapse retaining wall effect of mud property is good,
Fluid loss is low, low cost, environmental friendliness.
The content of the invention
It is an object of the invention to provide a kind of efficient instant mud powder and preparation method thereof, it has higher viscosity special
Property, the drop that solid particle can be promoted when using sinks, and controls sand content in mud in specifying and requiring, so as to allow the following of mud
Ring is up to 8 times using number of times.Simultaneously the mud has the filtration reduction for improving drilling fluid concurrently, effectively improves stable retaining wall effect
Really.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of efficient instant mud powder, it is formed by viscosifier, fluid loss additive and sediment accelerator compounding, each component institute
Accounting for weight portion is：70~85 parts of viscosifier；10~20 parts of fluid loss additive；5~15 parts of sediment accelerator.
Further scheme, the viscosifier are the one kind in non-ionic polyacrylamide, polyethylene glycol oxide, polyvinyl alcohol
Or it is various.
Further scheme, the non-ionic polyacrylamide molecular weight has 800~10,000,000, polyethylene glycol oxide molecular weight
There is 400~6,000,000, polyvinyl alcohol molecule amount to have 10~300,000.
Further scheme, the fluid loss additive is in SANWET, hydroxypropyl cellulose, potassium humate
One or more.
Further scheme, the sediment accelerator is the one kind or two in aluminium polychlorid and cationic-type polyacrylamide
Kind.
Further object is that providing a kind of preparation method of efficient instant mud powder, comprise the following steps：
Viscosifier, fluid loss additive, sediment accelerator are weighed by proportioning, closed type stirring and evenly mixing kettle, control stirred tank stirring are put into together
Speed is 20~30r/min, stirring and evenly mixing 15min, obtains final product efficient instant mud powder.
The present invention has the advantages that compared with existing technological achievements：
(1) viscosifier can dissolve at short notice completely, and in low-dosage condition high viscosity is issued to, and make mud wire drawing shape
State is good；
(2) fluid loss additive can mitigate the osmosiss of water, hence it is evident that reduce the fluid loss of mud, the stratum of surrounding is played
Good Stabilization；
(3) with sediment accelerator mud is done desanding purification work, it is to avoid secondary pile hole cleaning, control mud in containing sand
Amount, reduces abrasion of the excessive gravel to drill bit, and the recycling number of times of mud is improved to 8 times, saves Financial cost；
