Background technique
In the drilling engineering of land, drillng operation is often carried out using different drilling mud system, and different mud
The solid phase drilling wastes ingredient that slurry system generates is also far from each other.Wherein, drillng operation is carried out using clear water/polymer mud
Still account for exhausted large scale, the solid phase drilling wastes generated under this mud system are also most, while to the harm of environment with adopt
Compared to much smaller, relative harmlessization processing is also relatively easy to the solid phase drilling wastes generated with lignosulfonate mud, oil-base mud.
It is non-burning brick to refer to the materials for wall made without high-temperature calcination, while being also that a kind of pole for replacing clay brick has
The renewal product of development prospect.It is existing to discard solid phase production using clear water/polymer mud system drilling water-based drilling
Non-burning brick mainly discarded solid phase it is dry after add cement or other inorganic gel agent are made, because using clear water/polymer mud
The water-based drilling of slurry system drilling well discards the main composition material bentonite property in solid phase similar to clay property, cement water therewith
Change ineffective, in addition when raw material stirs, " pilling " phenomenon easily occurs in discarded solid phase, makes stirring unevenly, thus serious shadow
Non-burning brick mechanical property is rung, molding failure is even resulted in.Further, since the water base brill of clear water/polymer mud system drilling
The discarded solid phase particles diameter of well is small, and surface area is big, causes the cement slurry dosage of package huge, causes cement cost excessively high;And
Due to using clear water/polymer mud system drilling water-based drilling to discard, solid phase particles particle size distribution range is wider, and batch is raw
When producing non-burning brick, non-burning brick performance is unstable, and bad product rate is excessively high.
Summary of the invention
For existing water-based drilling, discarded solid phase non-burning brick compression strength is poor, presentation quality is poor, higher cost and system in batches
Performance is unstable when making, the high problem of bad product rate, and the present invention provides a kind of water-based drilling and discards that solid phase is non-burning brick and its preparation side
Method.
To achieve the above object of the invention, the embodiment of the present invention uses the following technical solution:
A kind of discarded solid phase of water-based drilling is non-burning brick, and the raw material components including following mass fraction: water-based drilling is discarded solid
Phase 30-50%;Cement 25%-40%;Building stones 20-40%;Early strength agent 0.1-0.2%;Water-reducing agent 0.1-0.2%, it is described water base
It includes that the discarded solid phase particles A of water-based drilling of different particle size distribution point and water-based drilling discard solid phase B that solid phase is discarded in drilling well, described
It is 30-200 mesh that water-based drilling, which discards solid phase particles A mesh number, and content is 90~95%;The water-based drilling discards solid phase particles B
200 mesh of mesh number >, content are 5~10%.

The cluster of grains of 30 mesh, is transported in pulverizer and is crushed;Mesh number is that the particle of 200 mesh of 30~200 mesh and mesh number > is then distinguished
Storage.
Further, the building stones are the rubble that continuous size fraction is 5-16mm, are gathered materials as non-burning brick, because particle compared with
Greatly, there is lesser surface area, can be fully wrapped around with less cement slurry, reduce cement consumption, reduces brick making cost.
Further, the early strength agent is Sulfates early strength agent, since clear water/polymer mud system drilling is water base
The discarded solid phase property of drilling well is similar with clay, mud property, and the first time handling time after causing into brick is relatively general non-burning brick slightly longer,
Therefore early strength agent is needed to improve performance.
Further, the water-reducing agent is poly carboxylic acid series water reducer, since clear water/polymer mud system drilling is water base
It is similar with clay, mud property that solid phase property is discarded in drilling well, and during brickmaking, polycarboxylate high performance water-reducing agent performance is contained
Soil amount influences minimum.

(3) mixed material is pressed, obtains adobe;
(4) adobe is conserved, is dried, and it is non-burning brick to obtain the discarded solid phase of water-based drilling.
Further, in step (1), the water additional amount is the 13~20% of cement, and water-based drilling discards solid phase particles
Surface area is bigger, and more water is needed to be wrapped up.
Further, in step (2), the mixing speed is 50-120rpm, mixing time 5-8min.
Further, in step (3), brickmaking machine is platform vibration, 60~90kN of exciting force, excited frequency 100Hz, maximum pressure
Power 10T.Using vibration sheeted product molding, can effectively reduce water-based drilling discard solid phase particles at after brick particulate interspaces and
Grain remains in the water content inside brick body because of hydration.
