Roj Drilling Qib CMC LV

Roj drilling qib carboxymethyl cellulose (CMC) LV yog hom dej-soluble polymer uas tau siv dav hauv kev lag luam roj thiab roj. Nws yog ib qho kev hloov kho derivative ntawm cellulose, ib tug natural compound pom nyob rau hauv cov nroj tsuag cell phab ntsa. CMC LV feem ntau yog siv los ua viscosifier, rheology modifier, kua poob reducer, thiab shale inhibitor hauv cov kua dej drilling. Hauv tsab xov xwm no, peb yuav tham txog cov khoom, kev siv, thiab cov txiaj ntsig ntawm cov roj drilling qib CMC LV.

Properties of CMC LV

Cov roj drilling qib CMC LV yog cov hmoov dawb los yog dawb, tsis muaj ntxhiab, thiab tsis qab ntsev hmoov uas yog soluble hauv dej. Nws yog muab los ntawm cellulose los ntawm kev hloov kho tshuaj lom neeg uas koom nrog kev sib ntxiv ntawm carboxymethyl pawg rau cov cellulose molecule. Qhov degree ntawm kev hloov pauv (DS) txiav txim siab tus naj npawb ntawm carboxymethyl pawg ib chav tsev piam thaj hauv cellulose molecule, uas cuam tshuam rau cov khoom ntawm CMC LV.

CMC LV muaj ntau yam khoom uas ua rau nws muaj txiaj ntsig zoo hauv cov dej drilling. Nws yog cov dej-soluble polymer uas tuaj yeem tsim cov kua nplaum nrog dej. Nws tseem yog pH-rhiab heev, nrog nws cov viscosity txo qis thaum pH nce. Cov cuab yeej no tso cai rau nws siv rau hauv ntau qhov chaw pH. Tsis tas li ntawd, CMC LV muaj cov ntsev siab ntev, uas ua rau nws tsim nyog rau kev siv hauv cov kua dej hauv cov dej hauv cov dej.

Kev siv CMC LV

Viscosifier
Ib qho ntawm cov kev siv tseem ceeb ntawm CMC LV hauv cov kua dej drilling yog ua viscosifier. Nws tuaj yeem pab ua kom cov viscosity ntawm cov dej drilling, uas yuav pab tshem tawm thiab thauj cov laum txiav mus rau qhov chaw. Cov cuab yeej no tseem ceeb tshwj xeeb tshaj yog nyob rau hauv kev ua haujlwm drilling qhov twg qhov tsim tau drilled tsis ruaj khov los yog qhov uas muaj kev pheej hmoo ntawm kev ploj mus.

Rheology Hloov Kho
CMC LV kuj tseem siv los ua tus hloov kho rheology hauv cov kua dej drilling. Nws tuaj yeem pab tswj cov khoom ntws ntawm cov kua dej, uas yog qhov tseem ceeb rau kev tswj xyuas qhov ruaj khov ntawm lub qhov dej. CMC LV tuaj yeem pab tiv thaiv sagging lossis teeb meem ntawm cov khib nyiab hauv cov kua dej drilling, uas tuaj yeem ua rau muaj teeb meem drilling.

Fluid Poob Reducer
CMC LV kuj tseem siv los ua cov kua dej poob hauv cov dej drilling. Nws tuaj yeem pab tsim lub ncuav mog qab zib nyias, impermeable lim rau ntawm phab ntsa ntawm lub qhov dej, uas yuav pab txo qhov poob ntawm cov kua dej hauv qhov tsim. Cov cuab yeej no tseem ceeb tshwj xeeb tshaj yog nyob rau hauv kev tsim nrog tsawg permeability los yog hauv kev sib sib zog nqus drilling ua haujlwm uas tus nqi ntawm kev ploj mus tuaj yeem yog qhov tseem ceeb.

Shale Inhibitor
CMC LV kuj tseem siv los ua shale inhibitor hauv cov kua dej drilling. Nws tuaj yeem pab tiv thaiv qhov o thiab tawg ntawm cov shale formations, uas tuaj yeem ua rau lub cev tsis ruaj khov thiab ploj mus. Cov cuab yeej no tseem ceeb tshwj xeeb tshaj yog nyob rau hauv kev ua haujlwm drilling uas qhov tsim tau drilled yog shale.

Cov txiaj ntsig ntawm CMC LV

Txhim kho Drilling Efficiency
CMC LV tuaj yeem pab txhim kho kev ua haujlwm drilling los ntawm kev txo cov kev pheej hmoo ntawm kev poob qis, tswj kev ruaj ntseg zoo, thiab txhim kho cov dej hauv qhov dej. Cov cuab yeej no tuaj yeem pab txo qis cov nqi drilling thiab txhim kho tag nrho kev ua haujlwm ntawm kev ua haujlwm drilling.

Txhim kho Wellbore Stability
CMC LV tuaj yeem pab txhim kho kev ruaj ntseg zoo los ntawm kev tswj cov khoom ntws ntawm cov dej drilling thiab tiv thaiv qhov o thiab tawg ntawm cov shale formations. Cov cuab yeej no tuaj yeem pab txo qis qhov kev pheej hmoo ntawm kev puas tsuaj los yog tawg, uas tuaj yeem raug nqi thiab txaus ntshai.

Txo kev cuam tshuam ib puag ncig
CMC LV yog cov khoom siv biodegradable thiab ib puag ncig zoo uas tsis muaj kev phom sij rau ib puag ncig. Cov cuab yeej no ua rau nws muaj kev xaiv zoo rau kev ua haujlwm drilling hauv thaj chaw rhiab heev.

Nqi-zoo
CMC LV yog qhov kev xaiv zoo rau cov dej drilling piv rau lwm cov khoom siv hluavtaws thiab cov khoom siv ntxiv. Nws tau yooj yim muaj thiab muaj tus nqi qis dua piv rau lwm cov khoom siv hluavtaws polymers thiab cov khoom siv ntxiv, uas ua rau nws muaj kev xaiv zoo rau ntau qhov kev ua haujlwm drilling.

Ntau yam
CMC LV yog cov khoom siv ntau yam polymer uas tuaj yeem siv rau ntau yam ntawm cov dej drilling. Nws tuaj yeem siv rau hauv cov dej tshiab, dej ntsev-raws li, thiab roj-based drilling kua. Qhov kev ua tau zoo no ua rau nws nrov polymer hauv kev lag luam roj thiab roj.
