Frac Sand yog dab tsi? Yuav siv li cas hauv hydraulic fracturing?
Frac xuab zeb yog siab -purity quartz xuab zeb nrog cov tawv tawv thiab sib npaug. Vim nws cov duab, nws tuaj yeem sau cov pob txha uas tsim los ntawm hydraulic fracturing kua. Qhov no ua rau cov pob txha tawg, tso cai rau cov roj los yog cov pa roj ntsha tuaj yeem yooj yim tawm ntawm qhov dej.
Vim li cas Frac Sand tseem ceeb?
Frac xuab zebtej zaum yuav zoo li yooj yim, tab sis nws yog lub hauv paus ntawm cov txheej txheem hydraulic fracturing. Nws pab ua kom cov pob txha qhib, ua kom txoj hauv kev ua kua dej thiab ua kom tag nrho cov khoom tsim tawm. Xav txog qhov no: yog tias cov pob txha tawg tam sim ntawd kaw tom qab cov kua dej tawg, koj tau siv zog ntau heev kom rov qab los tsawg heev. High- cov neeg ua haujlwm zoo ua kom cov kev no tseem qhib.
Puas muaj lwm txoj hauv kev?
Tej zaum koj yuav tau hnov cov resin-coated xuab zeb lossis ceramic proppants. Txawm hais tias cov ntaub ntawv no yuav muaj txiaj ntsig zoo hauv qhov tshwj xeeb siab - qhov chaw siab, feem ntau cov neeg ua haujlwm tseem cia siab rau cov xuab zeb vim nws cov nqi- ua tau zoo thiab kev ua tau zoo. Kev nkag siab txog cov kev xav tau tshwj xeeb ntawm koj qhov tsim yog qhov tseem ceeb.
Ntau hom thiab qib ntawm Frac Sand
Cia peb saib cov hauv paus ntawm ntau hom frac xuab zeb. Yog tias koj tab tom yuav proppant thawj zaug, koj yuav tsis meej pem los ntawm ntau qhov ntau thiab tsawg mesh. Ntawm no yog ib qho kev sib cais:
Mesh Loj thiab nws qhov tseem ceeb
Mesh loj yog hais txog qhov ntau ntawm qhov loj me hauv cov xuab zeb frac. Piv txwv li, 40/70 mesh xuab zeb muaj cov khoom tuaj yeem dhau los ntawm 40-mesh screen tab sis tsis yog 70-mesh screen. Qhov loj mesh loj (piv txwv li, 30/50 mesh) qhia cov khoom loj dua, thaum cov lej me me (piv txwv li, 100 mesh) qhia cov khoom me me. Qhov loj mesh koj xaiv yuav tsum phim cov yam ntxwv ntawm lub reservoir thiab fracturing txoj kev. Cov xuab zeb zoo dua tuaj yeem nkag mus rau cov pob txha pob txha, thaum cov xuab zeb coarser tuaj yeem txhawb nqa cov kab tawg ntau dua.
100 Mesh, 40/70 Mesh, thiab lwm yam
100 mesh: Cov khoom zoo heev, zoo tagnrho rau drilling hauv ultra- nruj formations.
40/70 mesh: Ib qho loj me rau ntau qhov kev ua haujlwm slickwater fracturing, muab qhov sib npaug ntawm qhov loj thiab lub zog.
30/50 mesh: Coarser tshaj 40/70 mesh, haum rau formations uas yuav lis loj hais. Kev xaiv qhov loj me yog nyob ntawm qhov chaw kaw qhov kaw qhov siab, qhov yuav tsum tau ntws, thiab cov txheej txheem tshwj xeeb uas koj siv.
