"Frac xuab zeb" thiab "fracking xuab zeb" yog hais txog tib yam khoom: siab -purity, crush-resistant silica xuab zeb siv nyob rau hauv hydraulic fracturing. Cov xuab zeb tshwj xeeb no ua raws li cov khoom siv, cov khoom siv tsim los ua kom cov pob txha tawg tau qhib kom muaj roj thiab roj ntws.
Hom Frac Sand thiab Proppants
Kev xaiv ntawm proppant nyob ntawm qhov tshwj xeeb siab thiab cov xwm txheej ntawm kev tsim geological. Thaum siv ntau yam khoom siv, ntau hom frac xuab zeb yog qhov ntau tshaj.
Northern Dawb Sand
Qhov no frac xuab zeb yog suav hais tias yog qhov zoo tshaj plaws vim nws siab purity, siab zog, thiab zoo particle roundness. Nws cov kav ntev ua rau nws haum rau ntau yam kev ua haujlwm hydraulic fracturing, nrog rau siab - qhov dej siab.
Brown Sand
Kuj hu ua Hickory xuab zeb lossis Brady xuab zeb, cov xuab zeb no yog los ntawm Texas thiab muaj cov ntsiab lus qis dua quartz tshaj li Northern White xuab zeb. Nws feem ntau yog siv hauv cov qhov dej ntiav ntiav nrog qis qis.
Resin-Coated Sand
Qhov no yog frac xuab zeb coated nrog ib txheej ntawm resin. Cov txheej txheej resin txhim kho lub zog ntawm cov proppant thiab pab tiv thaiv cov proppant los ntawm ntws rov qab los ntawm kev tawg nrog cov roj thiab roj. Cov txheej txheej cob khi cov xuab zeb ua ke nyob rau hauv qhov tawg, txhim kho ntev - lub sij hawm zoo productivity.
Ceramic Proppants
Ceramic proppantsyog lwm txoj hauv kev xuab zeb, ua los ntawm sintered bauxite lossis alumina. Thaum kim dua, lawv muaj zog dua thiab haum rau qhov sib sib zog nqus tob, siab -siab formations uas frac xuab zeb yuav tsoo.
Proppants kuj tau muab cais los ntawm mesh loj, uas qhia txog particle txoj kab uas hla. Feem ntau mesh muaj xws li 20/40 mesh, 30/50 mesh, thiab 100 mesh. Qhov kev xaiv ntawm mesh loj nyob ntawm qhov xav tau tawg qhov dav thiab cov yam ntxwv ntawm lub pas dej; finer particles muab cov cheeb tsam ntau dua, thaum cov khoom loj dua muab kev txhawb nqa zoo dua.
