Roj Drilling qib CMC

Roj Drilling qib CMC Sodium carboxymethyl celluloseis ua los ntawm ntuj cellulose los ntawm kev hloov tshuaj ntawm cov dej-soluble cellulose ether derivatives, yog ib qho tseem ceeb dej-soluble cellulose ether, dawb los yog daj hmoov, tsis muaj tshuaj lom, tsis qab, nws yuav yaj nyob rau hauv dej, muaj zoo kub stability thiab ntsev tsis kam, antibacterial.Cov kua slurry npaj los ntawm cov khoom no muaj cov dej tsis zoo, inhibition thiab kub tsis kam.Dav siv nyob rau hauv cov roj drilling, tshwj xeeb tshaj yog dej ntsev Wells thiab offshore roj drilling.

Roj Drilling qib CMC cov khoom tau muab faib ua cov viscosity siab (HV) thiab qis viscosity (LV) pawg, uas yog cov khoom siv high-tech nrog ywj siab cov cuab yeej cuab tam ntawm lub tuam txhab.Nws belongs rau anionic cellulose ether, thiab muaj cov yam ntxwv ntawm siab purity, high degree ntawm kev hloov thiab uniform tis ntawm hloov gao.Nws tuaj yeem siv los ua tus neeg sawv cev thickening, rheological regulator, dej poob reducer, thiab lwm yam. CMC nrog cov viscosity siab thiab qis viscosity muaj kev pom zoo txo ​​qis hauv cov dej tshiab thiab dej hiav txwv, thiab yog ib qho khoom tseem ceeb hauv av nkos compatibility.CMC ua los ntawm peb lub tuam txhab yog ib yam khoom uas muaj purified heev nrog dawb ntws hmoov nyob rau hauv tsos thiab pob tshab viscous kua nyob rau hauv aqueous tov.

Khoom nta

Carboxymethyl cellulose sodium ntsev feem ntau yog siv los ua viscosity nce thiab pom txo tus neeg sawv cev hauv cov kua dej.Qhov ntev molecular saw ntawm carboxymethyl cellulose sodium ntsev tuaj yeem adsorb nrog ntau cov av nplaum, ua kom cov cementation ntawm av nkos ncuav mog qab zib, inhibit shale hydration expansion thiab consolidate zoo phab ntsa.Sodium carboxymethyl cellulose aqueous tov muaj ntau yam zoo heev thiab tshuaj stability, tsis yooj yim rau corrosion thiab metamorphic, tsis muaj teeb meem rau lub cev kev nyab xeeb, ncua kev kawm ntawv thiab ruaj khov emulsification, zoo adhesion thiab ntsev kuj.Zoo stability rau roj thiab organic solvents.

(1) Cov av nkos uas muaj CMC tuaj yeem ua rau cov phab ntsa zoo tsim nyias thiab ruaj khov, tsis tshua muaj dej permeability lim ncuav mog qab zib, thiaj li txo cov dej poob.

(2) Tom qab ntxiv CMC rau cov av nkos, qhov laum tuaj yeem tau txais qis qis qis qis qis, kom cov av nkos yooj yim tso cov roj ntim rau hauv nws, thiab cov khib nyiab pov tseg sai sai hauv cov av nkos.

(3) Drilling av nkos, zoo li lwm yam kev tshem tawm dispersions, muaj qee lub neej, uas tuaj yeem ruaj khov thiab ntev los ntawm kev ntxiv CMC.

(4) Cov av nkos uas muaj CMC tsis tshua muaj kev cuam tshuam los ntawm cov pwm thiab yog li tsis tas yuav tsum tswj hwm PH siab lossis siv cov tshuaj tua kab mob.

(5) Muaj CMC raws li qhov drilling av nkos ntxuav cov kua dej, tuaj yeem tiv taus cov pa phem ntawm ntau cov ntsev soluble.

(6) CMC muaj av nkos, kev ruaj ntseg zoo, txawm tias qhov kub siab tshaj 150 ℃ tseem tuaj yeem txo cov dej poob.

Lub siab viscosity, siab hloov CMC yog haum rau cov av nkos nrog tsawg ntom, thaum tsis tshua muaj viscosity, siab hloov CMC yog haum rau av nkos nrog siab ceev.CMC muaj peev xwm tswj tsis tau dej ntau, pom kev poob zoo, ntawm qhov qis dua, tuaj yeem tswj cov dej poob ntawm qib siab dua, tsis muaj kev cuam tshuam rau lwm yam av nkos;Zoo kub tsis kam, zoo ntsev tsis kam, tshwj xeeb tshaj yog haum rau offshore drilling thiab sib sib zog nqus qhov yuav tsum tau ntawm natural gas drilling, khawb zoo thiab lwm yam dej num.Raws li ib tug sib sib zog nqus-dej colloid nyob rau hauv drilling av nkos system, nws yuav siv tau raws li cov kua los txo tus neeg saib xyuas thiab viscosity nce tus neeg sawv cev.

Fkev ua haujlwm:

(1) sai sai yaj hauv dej txias lossis dej kub;

(2) tuaj yeem siv ua tus neeg ua kom tuab, rheological tswj tus neeg saib xyuas, nplaum, stabilizer, tiv thaiv colloid, tus neeg saib xyuas kev ncua thiab tus neeg saib xyuas dej;

Hauv kev lag luam roj av, CMC yog tus neeg sawv cev zoo drilling av nkos thiab kev npaj cov khoom ua tiav cov kua dej, siab slurry tsim tus nqi, zoo ntsev tsis kam.Roj Drilling qib CMC yog ib qho zoo heev kua poob txo tus neeg sawv cev rau cov av nkos dej tshiab thiab seawater av nkos los nag saturated ntsev av, thiab muaj viscosity lifting muaj peev xwm thiab kub tsis kam (150 ℃).Haum rau kev npaj cov dej tshiab, seawater thiab saturated brine tiav cov kua, thiab calcium chloride hnyav tuaj yeem tsim tau rau ntau qhov ntom ntom ntawm cov kua tiav tiav, thiab cov kua tiav tiav viscosity thiab cov kua dej tsawg.Peb cov viscosity siab thiab qis viscosity CMC cov khoom ua tau raws li GB / T 5005 tus qauv, European OCMA tus qauv thiab API 13A tus qauv.

Nrov qib

Daim ntawv thov: 

(1) Kev siv CMC hauv cov kua dej drilling.

CMC yog qhov zoo tshaj plaws rau kev siv los ua tus inhibitor thiab kua poob reducer.Cov kua slurry npaj los ntawm CMC inhibits dispersion thiab expansion ntawm av nplaum thiab shale nyob rau hauv high-ntse media, yog li tswj kom zoo phab ntsa paug.

(2) Kev siv CMC hauv cov dej ua haujlwm.

Cov kua dej ua haujlwm tau npaj nrog CMC yog cov khoom qis thiab tsis thaiv qhov permeability ntawm thaj chaw tsim khoom vim yog cov khoom khib nyiab.Thiab nws muaj dej tsawg, kom cov dej rau hauv cov txheej txheem ntau lawm yog txo, thiab cov dej yuav raug thaiv los ntawm emulsion thiab tsim ib qho dej tuav phenomenon.

Cov kua dej ua haujlwm tau tsim nrog CMC muab qhov zoo dua lwm cov kua dej ua haujlwm.

Tiv thaiv cov txheej txheem ntau lawm los ntawm kev puas tsuaj;

Cleanhole portability thiab txo borehole tu;

Nws yog resistant rau infiltration ntawm dej thiab silt, thiab tsis tshua muaj blistered;

Nws tuaj yeem khaws cia lossis rov siv dua los ntawm qhov dej mus rau qhov zoo ntawm tus nqi qis dua li cov dej ua haujlwm ua haujlwm hauv av.

(3)Kev sivntawm CMC hauv cov kua dej tawg.

Cov kua fracturing npaj los ntawm CMC tuaj yeem tiv taus 2% KCI cov tshuaj (nws yuav tsum tau ntxiv thaum npaj cov kua fracturing), muaj cov solubility zoo, siv tau yooj yim, tuaj yeem npaj rau ntawm qhov chaw, thiab muaj qhov nrawm nrawm thiab muaj zog xuab zeb nqa peev xwm.Nws muaj txiaj ntsig zoo dua thaum siv hauv cov txheej txheem osmotic siab.
