Fracturing xuab zeb yog high-purity quartz xuab zeb nrog super muaj zog siab tsis kam thiab siab roundness. Nws feem ntau yog ua los ntawm ntuj quartz xuab zeb los ntawm ntau cov txheej txheem thiab kev ua haujlwm zoo. Nws yog tsuas yog siv nyob rau hauv kev lag luam roj, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov ntawm hydraulic fracturing, uas yog, siv ib tug high-pressure dej twj tso kua mis los txhaj fracturing kua rau hauv cov roj thiab roj reservoir rau crushed reservoir thiab tau txais cov khoom siv roj thiab roj.
Fracturing xuab zeb yog hu ua "proppant" vim hais tias nws txhawb kev qhib cov kab nrib pleb los ntawm kev tsim cov pore network, tso cai rau cov kua roj ntws tawm ntawm pob zeb thiab mus rau hauv qhov dej. Txawm hais tias muaj lwm hom proppants xaiv los ntawm, fracturing xuab zeb muaj qhov tshwj xeeb compressive brittleness thiab ib puag ncig particle zoo, uas ua rau lawv zoo heev rau cov txheej txheem fracturing.
Nyob rau hauv cov roj teb, fracturing yog hais txog ib txoj kev siv hydraulic nkaus los tsim cov kab nrib pleb hauv cov roj thiab cov roj reservoirs thaum lub sij hawm roj los yog natural gas extraction, tseem hu ua hydraulic fracturing. Hydraulic fracturing thev naus laus zis hais txog kev siv cov kua dej tawg rau hauv cov roj hauv qhov dej siab kom ua kom muaj kev kub siab nyob hauv qab ntawm qhov dej. Thaum lub siab txaus kom tawg pob zeb tsim, cov kab nrib pleb yuav tsim nyob rau hauv kev tsim thiab nthuav mus rau hauv qhov chaw. Txhawm rau kom cov kab nrib pleb qhib, tom qab lub pob zeb tawg, nws yog ib qho tsim nyog yuav tsum tau sau cov kab nrib pleb nrog cov khoom siv uas siv cov kua dej tawg.
Hom fracturing xuab zeb
- Quartz xuab zeb
- Hlau aluminium pob
- Walnut plhaub
- iav hlaws dai
- Cov khoom yas
- Cov pob hlau
- Ceramic hais
- Coated xuab zeb
Covpetroleum fracturing proppantstam sim no siv thoob ntiaj teb feem ntau muab faib ua peb hom: quartz xuab zeb proppants, ceramsite proppants, thiab coated proppants. Hauv kev tsim cov shale gas fracturing nyob rau hauv North America, qhov kev faib ua feem ntawm ceramsite proppants siv yog maj mam txo. Xav txog tus nqi thiab cov txiaj ntsig kev lag luam ntawm kev tawg, quartz xuab zeb proppants dominate daim ntawv thov.
Cov txheej txheem ntawm fracturing xuab zeb
Cov txheej txheem tsim cov xuab zeb tawg muaj xws li: cov khoom siv raw - kev faib tawm - sib nqus sib nqus - ntxuav - ziab thiab tshuaj xyuas - kev tswj cov khoom pov tseg. Cov khoom siv xuab zeb tawg muaj xws li: silos, vibrating feeders, vibrating screens, sib nqus sib nqus, silicon washers, tshuab ziab khaub ncaws, square viav vias cov ntxaij vab tshaus, concentrators, thiab lub thawv lim xovxwm.
- Kev tshuaj ntsuam xyuas: Ua ntej, cov xuab zeb tawg nkag mus rau hauv silo thiab raug tshuaj xyuas los ntawm ib qho screen vibrating linear. Tom qab kev tshuaj ntsuam, ntau tshaj 20 hom fracturing xuab zeb raug rho tawm.
- Sib nqus sib cais: Sib nqus sib cais yog ua los ntawm kev sib nqus sib nqus rau<20 types of purposes.
- Scrubbing: Kev tu kom muaj zog yog ua los ntawm lub tshuab ntxhua khaub ncaws, thiab tom qab ntawd nws nkag mus rau hauv cov xuab zeb ntxhua kom ntxuav thiab lub cev qhuav dej. Tom qab sib cais los ntawm impeller separator, nws nkag mus rau hauv lub cev qhuav dej ntawm lub vijtsam kom lub cev qhuav dej.
- Kev ziab thiab kev tshuaj ntsuam: Cov xuab zeb uas ntxuav tau nkag mus rau hauv lub tshuab ziab khaub ncaws kom qhuav, thiab tom qab ntawd nkag mus rau lub voj voog square rau kev tshuaj ntsuam xyuas zoo.
- Kev tswj cov khoom pov tseg: Cov dej ntws tawm ntawm cov txheej txheem ntxuav ore nkag mus rau hauv cov thickener rau cov dej huv rov qab. 80% ntawm cov dej khib nyiab hauv cov txheej txheem no tuaj yeem rov ua dua tshiab, thiab cov dej hauv qab ntawm cov thickener nkag mus rau hauv cov xovxwm lim kom ua tiav rau hauv av nkos ncuav mog qab zib.
Kev ua tau zoo ntawm cov xuab zeb tawg
1. Fracturing xuab zeb yuav tsum muaj lub zog txaus compressive thiab hnav tsis kam, muaj peev xwm tiv taus lub zog thiab kev sib txhuam thaum txhaj tshuaj, thiab txhawb nqa cov pob txha pob txha zoo.
2. Cov txheeb ze ntawm cov xuab zeb tawg yuav tsum tsis tshua muaj kom yooj yim rau kev nkag mus rau hauv qhov dej.
3. Nyob rau hauv 200 degree, yeej tsis muaj tshuaj tiv thaiv ntawm fracturing xuab zeb hais thiab fracturing kua thiab reservoir kua, thiab cov kua qaub solubility yog tsawg tshaj li 7%.
4. Fracturing sand particles kuj zoo ib yam, thiab tsis muaj qhov sib txawv loj.
