~1500 μm of little particle, then 20~100 μm of spheroidal full particles are made by Raymond mill, spheroidal full particle passes through
Elevator enters distributing device, then is entered by distributing device in expansion sintering furnace, by 800~950 DEG C of expansions, 1000~1500 DEG C of tables
Face melting is fired, cooling, and the hollow pottery of lead-zinc ore closed pore of 50~100 μm of wall thickness, 50~350 μm of particle diameter is obtained through pneumatic separating
Porcelain microballon.
Second step, the dispensing of antiseepage well cementation test block：By 40~50wt% of G level oil-well cements, 10~15wt% of superfine cement, grain
Footpath is 50~350 μm of footpath, 25~35wt% of lead-zinc ore closed pore hollow ceramic microspheres, 5~7wt% of flyash, pure of loss on ignition 1.1%
99.9% 1.5~2wt% of calcium oxide, 0.5~1.0wt% of sodium sulphate, 1~5wt% of silica flour and 1.0~2wt% of alumina powder samplings are spent,
Obtain compound, the percentage by weight sum of above component is 100%, and activated silica, aluminium and G level oil-well cements react generation
Hydrated calcium silicate gel shape material and other gels, the basal body structure hole of cement mortar diminish, and form high vapour lock well cementation test block, drop
The permeability of low well cementation test block, improves the flow of pore resistance of well cementation test block, improves test block heat resistance, calcium oxide aquation
The substantial amounts of heat of reaction release, improves the temperature of test block, and silica flour and alumina powder G level oil-well cements react and generate aquation silicic acid
Calcium spawn and other gels, the basal body structure hole of cement mortar diminish, and form high vapour lock well cementation test block, reduce well cementation
The permeability of test block, the flow of pore resistance of well cementation test block is improved, strengthen test block resistance to compression and fracture resistence force；
The preparation of 3rd step, antiseepage well cementation test block heatproof slurries：Compound is mixed to get by the percentage by weight sampling of second step,
Compound is stirred, sized mixing with 0.5~0.7 ratio of mud, wherein ash is compound, adding compound gross weight is
0.2~0.5% foaming agent, foaming agent are one kind therein in aluminium powder cream, the compound of aluminium or ammonium hydrogen carbonate, add hair
Infusion hydration reaction generates bubble, forms the slurries of expansion, reduces the density of slurries, forms high vapour lock well cementation test block, reduces
Cement the well test block permeability, improve well cementation test block flow of pore resistance, with well cementation depth increase, high density slurries,
The bottom of test block pressure increase, easily cause oil well cementing test block weightlessness collapse, section fault rupture, cause oil well infiltration, landslide,
The ceramic fibre that compound gross weight is 5~8% will be added in the slurries of preparation, by roller rotary spreading, realization is uniformly stirred
Mix, ceramic fibre is a kind of fibrous light refractory material, has good in light weight, high temperature resistant, heat endurance, low thermal conductivity, ratio
Thermal capacitance is small and mechanical resistant vibrations, adds the slurries of ceramic fibre, the increase of test block crushing resistance, fold resistance enhancing after grout cures；
4th step, antiseepage well cementation test block mobility slurries preparation, will the 3rd step prepare slurries in add after nodularization grain
Footpath is 20~50 μm of graphite microbeads, and addition is 1~3% graphite microbeads of second step compound weight, then adds second
The swollen resin of 0.5~1.0% water imbibition of compound weight is walked, is stirred, increases the mobility of slurries, after grout cures
Test block shock resistance, toughness enhancing, swollen resin water suction test block shrinkage factor it is low, reduce test block drop dehydration quantity, slurries
Density is in 0.8~1.2g/cm3；
5th step, testing performance index：
A, the measure of expansion slurry flow rate：Take the 4th step to prepare slurries, pour into slurries flowing speedometer, observe and record slurry
The distance of motion in the flow rate of liquid, i.e. unit interval；
B, the volume density rate of change experiment of test block：4th step is prepared into slurries, pours into one group of three pieces of length and width, high respectively 53mm*
In 53mm*53mm die trials, conserved respectively 24 hours, 48 hours, 96 hours, after the demoulding in the water-bath curing box of 52 DEG C of constant temperature
Soaked 1 hour in cold water, the test block after solidification is put into the volume density rate of change experiment that test block is carried out on forcing press, test block
Volume density rate of change is less than 0.02%, and the porosity of test block is low, and permeability is poor；
C, the bleed experiment of test block：The slurries prepared are poured into die trial, die trial is suspended among beaker, beaker mouth hermetic bag
Sealing, slurries take out die trial after test block is frozen into from beaker, weigh the weight that moisture is separated out in beaker, observe slurry
Condition, if layering, i.e., homogeneity, the test block vertical section Density Distribution after solidification are uniform；
D, barrier performance is tested：The slurries for taking the 4th step to prepare are poured into water-impervious analogue experiment installation, water-impervious simulated experiment
