Khoom Description
Roj proppant yog cov khoom siv uas ua lub luag haujlwm tseem ceeb hauv kev tshawb nrhiav roj thiab roj. Nws yog tsuas yog siv rau kev txhawb nqa hauv av hauv cov roj av kom nce cov roj thiab cov pa roj. Nov yog qee qhov kev ua tau zoo ntawm cov roj proppant:
1. Muaj zog thiab hnav tsis kam
Proppants yuav tsum muaj lub zog txaus compressive thiab tiv thaiv hnav, muaj peev xwm tiv taus lub zog thiab kev sib txhuam thaum txhaj, thiab txhawb nqa cov pob txha pob txha zoo. Qhov no ua kom ntseeg tau tias cov khoom siv tuaj yeem tswj tau nws qhov kev ruaj ntseg nyob rau hauv cov xwm txheej huab cua, yog li tswj lub xeev qhib ntawm pob txha thiab txhim kho roj thiab roj conductivity thiab ntau lawm.
2. Tsawg ceev thiab zoo pumpability
Cov txheeb ze ntom ntom ntawm cov khoom siv yuav tsum yog tsawg kom lawv tuaj yeem yooj yim pumped downhole. Tsawg-density proppant tuaj yeem tsis tsuas yog txhim kho downhole ua hauj lwm efficiency, tab sis kuj txo qhov cuam tshuam ib puag ncig. Tsis tas li ntawd, proppant nrog cov khoom sib xws thiab cov nplaim du tuaj yeem muab cov twj tso kua mis zoo dua thiab raug ncua, ua rau cov txheej txheem txhaj tshuaj smoother.
3. Specified particle loj ntau yam
Qhov loj me me ntawm cov khoom me me yuav tsum ua tau raws li cov qauv tsim ntawm cov roj sib txawv. Feem ntau hais lus, spherical particles nrog ib tug particle loj ntawm {{0}}.4 thiab 0.8 hli yog qhov zoo tshaj plaws vim hais tias lawv muaj peev xwm muab tau qhov zoo tshaj plaws kev txhawb zog thiab txaus conductivity. Kev tswj ntawm particle loj yog qhov tseem ceeb los xyuas kom meej qhov ua tau zoo thiab kav ntev.
4. Zoo tshuaj stability
Tus propant yuav tsum tsis txhob chemically react nrog cov kua fracturing thiab reservoir kua nyob rau hauv high kub. Qhov no txhais tau hais tias tus proppant yuav tsum muaj kev ruaj ntseg tshuaj zoo los tiv thaiv cov teeb meem cuam tshuam thiab xyuas kom meej tias nws qhov kev ua tau zoo tsis hloov pauv mus rau lub sijhawm.
5. Cov yam ntxwv tiv thaiv ib puag ncig
Petroleum fracturing proppant yog ib yam khoom zoo rau ib puag ncig, thiab nws txoj kev siv pab txo qis kev cuam tshuam rau ib puag ncig. Cov txheej txheem tsim khoom ntawm proppant siv ib puag ncig yam tseem ceeb rau hauv kev xav. Piv txwv li, qee lub tuam txhab siv cov cuab yeej siv hluav taws xob pov tseg kom txo tau lub zog siv.
Piv txwv li, cov yam ntxwv ntawm kev ua tau zoo ntawm cov roj av fracturing proppant feem ntau yog tshwm sim nyob rau hauv nws lub zog siab, tsawg ntom, haum particle loj, zoo heev tshuaj stability thiab ib puag ncig tiv thaiv yam ntxwv. Cov khoom no ua rau muaj kev txhawb nqa los ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm hnyav thiab pab txhawb kev txhim kho kev lag luam roj thiab roj.
