Dab tsi yog kev siv cellulose hauv cov av nkos

Cellulose, complex carbohydrate pom nyob rau hauv cell phab ntsa ntawm cov nroj tsuag, plays lub luag hauj lwm tseem ceeb nyob rau hauv ntau yam lag luam, nrog rau cov roj thiab roj sector. Hauv cov av nkos, cellulose ua haujlwm ntau lub hom phiaj vim nws cov khoom tshwj xeeb thiab cov yam ntxwv.

Drilling av, tseem hu ua drilling kua, yog ib qho tseem ceeb ntawm cov txheej txheem ntawm drilling roj thiab roj qhov dej. Nws ua haujlwm ntau yam tseem ceeb, suav nrog kev ua kom txias thiab lubricating lub laum me ntsis, nqa cov pob zeb txiav rau saum npoo, tswj kev ruaj ntseg zoo, thiab tiv thaiv kev tsim kev puas tsuaj. Txhawm rau ua kom tiav cov haujlwm no kom zoo, cov av nkos yuav tsum muaj qee yam khoom xws li viscosity, kev tswj tsis tau dej, tshem tawm cov khib nyiab, thiab kev sib raug zoo nrog cov xwm txheej hauv qab.

Cellulosefeem ntau yog siv nyob rau hauv drilling av formulations raws li ib tug thawj additive vim nws tshwj xeeb rheological zog thiab versatility. Ib lub luag haujlwm tseem ceeb ntawm cellulose hauv cov av nkos yog muab viscosity thiab rheological tswj. Viscosity yog ib qho kev ntsuas ntawm cov kua dej tsis kam ntws, thiab nws yog ib qho tseem ceeb hauv kev tswj xyuas cov dej ntws uas xav tau ntawm cov av nkos. Los ntawm kev ntxiv cellulose, viscosity ntawm cov av nkos tuaj yeem hloov kho kom tau raws li cov kev cai tshwj xeeb ntawm kev ua haujlwm drilling. Qhov no yog qhov tseem ceeb tshwj xeeb hauv kev tswj tus nqi nkag mus, tiv thaiv cov kua dej poob rau hauv kev tsim, thiab nqa cov laum txiav rau saum npoo.

cellulose ua raws li cov viscosifier thiab cov kua dej tswj tus neeg sawv cev ib txhij. Raws li cov viscosifier, nws pab tshem tawm thiab thauj cov laum txiav mus rau saum npoo, tiv thaiv lawv los ntawm kev sib tsoo thiab sib sau rau hauv qab ntawm lub qhov dej. Qhov no ua kom muaj kev ua haujlwm zoo drilling thiab txo qhov kev pheej hmoo ntawm qhov teeb meem ntawm cov yeeb nkab. Tsis tas li ntawd, cellulose ua ib daim nyias nyias, impermeable lim ncuav mog qab zib rau ntawm phab ntsa ntawm lub qhov dej, uas pab tswj cov kua dej poob rau hauv kev tsim. Qhov no yog qhov tseem ceeb rau kev tswj kom muaj kev ruaj ntseg zoo thiab tiv thaiv kev tsim kev puas tsuaj los ntawm cov dej ntxeem tau.

Ntxiv nrog rau nws cov rheological thiab kua tsis tswj cov khoom, cellulose kuj muaj cov txiaj ntsig ib puag ncig hauv cov av nkos formulations. Tsis zoo li cov khoom siv hluavtaws, cellulose yog biodegradable thiab ib puag ncig tus phooj ywg, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev ua haujlwm zoo ib puag ncig. Nws biodegradability ua kom ntseeg tau tias nws tawg ib txwm dhau sijhawm, txo cov kev cuam tshuam ib puag ncig ntawm kev ua haujlwm drilling.

Cellulose tuaj yeem muab tso rau hauv cov av nkos hauv ntau hom, suav nrog cov hmoov cellulose, cellulose fibers, thiab cellulose derivatives xws licarboxymethyl cellulose (CMC)thiabHydroxyethyl Cellulose (HEC). Txhua daim ntawv muaj cov txiaj ntsig tshwj xeeb thiab kev ua haujlwm nyob ntawm qhov yuav tsum tau ua ntawm kev ua haujlwm drilling.

Powdered cellulose feem ntau yog siv los ua thawj viscosifier thiab cov kua dej tswj tus neeg sawv cev hauv cov av nkos. Nws yog yooj yim dispersible nyob rau hauv dej thiab nthuav tawm zoo heev ncua kev kawm ntawv cov khoom, ua rau nws zoo tagnrho rau nqa xyaum txiav mus rau saum npoo.

Cellulose fibers, ntawm qhov tod tes, ntev thiab fiber ntau dua li hmoov cellulose. Lawv feem ntau siv nyob rau hauv qhov hnyav av nkos systems, qhov twg high-density drilling kua yuav tsum tau los tswj kev tsim pressures. Cellulose fibers pab txhim kho cov qauv kev ncaj ncees ntawm cov av nkos, txhim kho qhov kev ua haujlwm ntawm lub qhov, thiab txo lub zog thiab rub thaum lub sijhawm ua haujlwm drilling.

Cellulose derivatives xws liCMCthiabHECyog cov tshuaj hloov kho cov ntaub ntawv ntawm cellulose uas muaj kev ua tau zoo zog. Lawv feem ntau siv rau hauv cov ntawv thov tshwj xeeb drilling av nkos qhov twg cov kev ua haujlwm tshwj xeeb yuav tsum tau ua. Piv txwv li, CMC tau dav siv los ua cov shale inhibitor thiab cov kua dej poob tswj tus neeg saib xyuas hauv cov av nkos, thaum HEC yog siv los ua rheology hloov kho thiab pom tus neeg saib xyuas hauv cov av nkos roj.

cellulose plays lub luag haujlwm tseem ceeb hauv kev tsim cov av nkos vim nws cov khoom tshwj xeeb thiab ntau yam. Los ntawm kev muab viscosity thiab rheological tswj kom txhim kho cov kua dej tsis zoo thiab kev ruaj ntseg ib puag ncig, cellulose muaj ntau yam txiaj ntsig hauv kev ua haujlwm drilling. Raws li kev lag luam roj thiab roj txuas ntxiv mus ntxiv, qhov kev thov kom muaj txiaj ntsig zoo thiab tus phooj ywg zoo ib puag ncig drilling av nkos kev daws teeb meem yuav tsum nce ntxiv, ntxiv qhov tseem ceeb ntawm cellulose ua ib qho tseem ceeb ntxiv hauv cov kua dej drilling.
