Proppants yog qhov tseem ceeb hauv hydraulic fracturing (los yog "fracking"). Lawv yog cov khoom me me, cov khoom sib xyaw nrog dej thiab tshuaj lom neeg thiab txhaj tshuaj hauv av nyob rau hauv siab kom cov pob txha tsim thaum lub sij hawm fracking txheej txheem qhib. Yog tias tsis muaj cov khoom siv, cov pob txha tawg yuav kaw, thiab cov roj lossis cov pa roj carbon monoxide tso tawm thaum lub sijhawm fracking yuav tsis tuaj yeem ntws mus rau saum npoo.
Muaj ntau ntau hom khoom siv hauv hydraulic fracturing, nrog rau cov xuab zeb proppants, ceramic proppants, thiab resin-coated proppants. Txhua hom muaj nws cov khoom tshwj xeeb thiab qhov zoo. Sand proppants yog hom siv dav tshaj plaws vim lawv cov nqi qis, cov khoom siv ntau, thiab muaj peev xwm tiv taus siab.Ceramic proppantsyog kim tshaj li xuab zeb propppants tab sis muaj zog thiab muaj ib tug ntau npaum li cas particle loj, tso cai rau kom zoo dua tswj qhov loj thiab cov duab ntawm cov fractures thaum lub sij hawm fracking. Resin-coated proppants zoo ib yam li ceramic proppants tab sis muaj cov resin txheej ntawm lawv qhov chaw, uas pab txhim kho lub zog thiab tiv thaiv kev degradation thaum lub sijhawm.
Nov yog qee cov ntsiab lus tseem ceeb uas yuav tsum nco ntsoov txog kev siv cov khoom siv:
1. Qhov loj thiab cov duab ntawm cov proppants yog qhov tseem ceeb hauv kev txiav txim siab qhov ua tau zoo ntawm cov txheej txheem hydraulic fracturing. Cov khoom me me yog qhov zoo dua rau kev tsim cov pob txha me me, thaum cov khoom loj dua yog qhov zoo dua rau kev tsim cov pob txha loj dua.
2. Tus nqi ntawm cov proppant siv nyob rau hauv hydraulic fracturing txheej txheem ho cuam tshuam rau tag nrho cov kev vam meej ntawm lub lag luam. Cov khoom me me dhau tuaj yeem ua rau cov kua dej tsis txaus los ntawm lub qhov dej, thaum cov khoom siv ntau dhau tuaj yeem ua rau lub qhov dej los yog cov pob zeb nyob ib puag ncig.
3. Cov khoom siv kuj tseem siv tau los tswj cov dej ntws hauv cov dej hauv av. Los ntawm kev txhaj tshuaj rau hauv lub qhov dej, ib qho kev thaiv tuaj yeem tsim los tiv thaiv cov dej tsis xav tau los ntawm kev nkag mus rau hauv qhov dej thiab cuam tshuam cov dej ntws ntawm cov roj lossis cov pa roj.
Zuag qhia tag nrho, proppants yog ib qho tseem ceeb ntawm cov txheej txheem hydraulic fracturing thiab tau hloov pauv cov roj thiab roj kev lag luam. Txawm hais tias kev txhawj xeeb txog kev cuam tshuam ib puag ncig ntawm hydraulic fracturing siv tau, lub luag haujlwm ntawm cov khoom siv hauv cov txheej txheem no tsis tuaj yeem raug saib xyuas. Los ntawm kev nkag siab tias cov khoom siv ua haujlwm li cas thiab ntau hom muaj, peb tuaj yeem nkag siab tob txog cov cuab yeej tseem ceeb no.
