Raws li lub ntiaj teb kev saib xyuas rau kev tiv thaiv ib puag ncig txuas ntxiv nce ntxiv, kev lag luam roj, raws li thaj chaw tseem ceeb ntawm cov khoom siv hluav taws xob, tau nyiam ntau yam rau nws cov teeb meem ib puag ncig. Hauv cov ntsiab lus no, kev siv thiab kev tswj cov tshuaj yog qhov tseem ceeb tshwj xeeb.Hydroxyethyl Cellulose (HEC), raws li cov khoom siv dej-soluble polymer, yog dav siv nyob rau hauv ntau yam ntawm cov roj kev lag luam vim nws cov kev ua tau zoo thiab kev tiv thaiv ib puag ncig, tshwj xeeb tshaj yog nyob rau hauv drilling kua, fracturing kua thiab av nkos stabilizers.
Cov yam ntxwv tseem ceeb ntawm HEC
HEC yog ib qho non-ionic polymer ua los ntawm kev hloov cov cellulose ntuj, uas muaj cov yam ntxwv tseem ceeb hauv qab no:
Biodegradability: KimaCell®HEC yog tsim los ntawm cov khoom siv ntuj tsim thiab tuaj yeem decomposed los ntawm cov kab mob, kom tsis txhob muaj cov pa phem nyob hauv ib puag ncig.
Tsawg toxicity: HEC ruaj khov nyob rau hauv aqueous tov, muaj tsawg toxicity rau lub ecosystem, thiab yog haum rau tej lub sij hawm nrog siab ib puag ncig yuav tsum tau.
Dej solubility thiab thickening: HEC muaj peev xwm yaj nyob rau hauv dej thiab tsim ib tug high-viscosity tov, uas ua rau nws zoo heev nyob rau hauv kho cov rheology thiab ncua kev kawm ntawv ntawm cov kua.
Cov ntawv thov tseem ceeb hauv kev lag luam roj
Kev siv hauv cov dej drilling
Drilling kua yog ib qho tseem ceeb hauv cov txheej txheem roj extraction, thiab nws cov kev ua tau zoo cuam tshuam ncaj qha rau drilling efficiency thiab tsim kev tiv thaiv. HEC, raws li cov thickener thiab kua poob reducer, tuaj yeem txhim kho cov khoom rheological ntawm cov dej drilling, thaum txo cov dej nkag mus rau hauv kev tsim thiab txo qhov kev pheej hmoo ntawm kev puas tsuaj. Piv nrog rau cov khoom siv hluavtaws hluavtaws, HEC muaj qhov pheej hmoo tsawg dua ntawm kev kis kab mob rau cov av ib puag ncig thiab cov dej hauv av vim nws cov toxicity tsawg thiab degradability.
Kev siv rau hauv cov kua dej tawg
Thaum lub sij hawm fracturing txheej txheem, fracturing kua yog siv rau tawg expansion thiab xuab zeb nqa. HEC tuaj yeem siv los ua cov thickener rau fracturing kua, txhim kho cov viscosity ntawm cov kua los txhim kho cov xuab zeb nqa peev xwm, thiab thaum tsim nyog, nws tuaj yeem degraded los ntawm enzymes los yog acids kom tso cov pob txha thiab rov tsim permeability. Qhov no muaj peev xwm los tswj kev degradation pab txo cov tshuaj seem, yog li txo cov kev cuam tshuam ntev ntawm kev tsim thiab cov dej hauv av.
Cov av nkos stabilizer thiab dej tsis tiv thaiv
HEC kuj tau siv dav hauv cov av nkos thiab cov dej tsis zoo, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias. Nws zoo heev stability thiab dej solubility tuaj yeem txo cov av nkos poob thiab tiv thaiv kev tsim kev ncaj ncees. Nyob rau tib lub sijhawm, txij li HEC tuaj yeem siv ua ke nrog lwm cov khoom siv hauv ib puag ncig, nws siv ntxiv txo qhov kev puas tsuaj rau ib puag ncig.
Kev cuam tshuam ib puag ncig
Txo cov pa phem ib puag ncig
Ib txwm siv tshuaj ntxiv xws li cov khoom siv hluavtaws polyacrylamide feem ntau muaj eco-toxicity siab, thaum HEC, vim nws lub hauv paus chiv keeb thiab tsis muaj tshuaj lom, txo qhov nyuaj ntawm kev kho cov pov tseg thiab ib puag ncig muaj kuab paug thaum siv hauv kev lag luam roj.
Txhawb kev txhim kho kom ruaj khov
Cov xwm txheej biodegradable ntawm HEC ua rau nws maj mam decompose rau hauv cov khoom tsis muaj teeb meem hauv qhov xwm txheej, uas yuav pab ua kom tiav kev kho ntsuab ntawm kev lag luam roj pov tseg. Tsis tas li ntawd, nws cov yam ntxwv ntawm kev muab tau los ntawm cov peev txheej txuas ntxiv dua tshiab kuj tseem ua raws li lub tswv yim ntawm kev txhim kho thoob ntiaj teb kom ruaj khov.
Txo kev puas tsuaj ib puag ncig ib puag ncig
Tsim kev puas tsuaj thiab tshuaj lom neeg cov khoom seem yog cov teeb meem tseem ceeb ntawm ib puag ncig hauv cov txheej txheem ntawm cov roj rho tawm. HEC txo qis kev pheej hmoo ntawm cov pa phem thib ob rau dej thiab av thaum txo kev tsim kev puas tsuaj thiab txhim kho cov txheej txheem drilling thiab tawg. Cov yam ntxwv no ua rau nws hloov pauv ntsuab rau cov tshuaj ib txwm muaj.
Kev sib tw thiab kev txhim kho yav tom ntej
Txawm tiasHECtau qhia txog qhov zoo ntawm kev tiv thaiv ib puag ncig thiab kev ua haujlwm, nws tus nqi siab thiab kev ua haujlwm tsis zoo nyob rau hauv cov xwm txheej huab cua (xws li kub siab, siab ntsev, thiab lwm yam) tseem yog qhov tseem ceeb uas txwv nws txoj kev nce qib. Kev tshawb fawb yav tom ntej tuaj yeem tsom mus rau kev hloov kho cov qauv ntawm HEC txhawm rau txhim kho nws cov ntsev tiv thaiv thiab kub siab. Kev txhawb nqa qhov loj thiab cov qauv siv ntawm HEC hauv kev lag luam roj kuj yog tus yuam sij rau kev paub txog nws qhov kev tiv thaiv ib puag ncig.
HEC ua lub luag haujlwm tseem ceeb hauv kev lag luam roj vim nws qhov kev ua tau zoo thiab kev tiv thaiv ib puag ncig. Los ntawm kev txhim kho kev ua haujlwm ntawm cov kua dej drilling, cov kua dej tawg thiab cov av nkos, KimaCell®HEC tsis tsuas yog txhim kho kev ua haujlwm ntawm cov roj extraction, tab sis kuj txo qis qhov tsis zoo ntawm ib puag ncig. Raws li kev hloov pauv ntawm lub ntiaj teb ntsuab ntsuab zog, kev txhawb nqa thiab kev siv ntawm HEC yuav muab kev txhawb zog rau kev txhim kho kev lag luam roj.
