Hydroxyethylcellulose (HEC) ua lub luag haujlwm tseem ceeb hauv kev lag luam roj drilling, tshwj xeeb tshaj yog nyob rau hauv cov dej drilling los yog av nkos. Drilling kua yog qhov tseem ceeb hauv cov txheej txheem roj zoo drilling, muab ntau yam haujlwm xws li cua txias thiab lubricating laum khoom, nqa drilling cuttings rau saum npoo, thiab tswj kev ruaj ntseg zoo. HEC yog ib qho tseem ceeb ntxiv hauv cov kua dej drilling, pab txhim kho lawv cov txiaj ntsig thiab kev ua haujlwm.
Taw qhia rau Hydroxyethyl Cellulose (HEC):
1. Cov qauv thiab cov khoom siv tshuaj:
Hydroxyethyl cellulose yog ib qho nonionic, dej-soluble polymer tau los ntawm kev hloov kho tshuaj ntawm cellulose.
Cov pab pawg hydroxyethyl hauv nws cov qauv muab nws solubility hauv dej thiab roj, ua rau nws muaj ntau yam.
Nws qhov hnyav molecular thiab qib ntawm kev hloov pauv cuam tshuam rau nws cov khoom rheological, uas yog qhov tseem ceeb rau nws qhov kev ua tau zoo hauv cov kua dej drilling.
2.Rheological hloov kho:
HEC yog siv los ua tus hloov kho rheology, cuam tshuam rau tus cwj pwm ntws thiab viscosity ntawm cov kua dej drilling.
Kev tswj ntawm cov khoom rheological yog qhov tseem ceeb rau kev ua kom zoo dua qhov kev ua tau zoo ntawm cov kua dej hauv qhov sib txawv downhole.
3. Lim tswj:
HEC ua raws li tus neeg saib xyuas kev pom, tiv thaiv cov kua dej ntau dhau rau hauv kev tsim.
Cov polymer ua ib daim nyias nyias, impermeable lim ncuav mog qab zib rau ntawm lub qhov dej, txo cov dej nkag nkag mus rau hauv cov pob zeb ib puag ncig.
4. Ntxuav thiab dai:
HEC pab ncua kev xyaum txiav, tiv thaiv lawv los ntawm kev nyob hauv qab ntawm lub qhov dej.
Qhov no ua kom lub qhov dej huv huv zoo, ua kom lub qhov dej huv huv thiab tiv thaiv cov blockages uas tuaj yeem cuam tshuam cov txheej txheem drilling.
5. Lubrication thiab txias:
Lub lubricating zog ntawm HEC pab txo kev sib txhuam ntawm txoj hlua tho thiab qhov dej, yog li txo qis hnav thiab tsim kua muag ntawm cov khoom siv drilling.
Nws kuj tseem pab kom cov cua sov dissipate, pab kom txias ntawm lub laum me ntsis thaum lub sijhawm ua haujlwm drilling.
6. Tsim stability:
HEC txhim khu kev ruaj ntseg zoo los ntawm kev txo qis kev pheej hmoo ntawm kev tsim kev puas tsuaj.
Nws pab tswj kev ncaj ncees ntawm lub qhov dej los ntawm kev tiv thaiv kev sib tsoo lossis kev sib tsoo ntawm cov pob zeb uas nyob ib puag ncig.
7. Dej-raws li drilling kua:
HEC feem ntau yog siv rau hauv cov dej-raws li drilling kua rau impart viscosity thiab stability rau cov dej drilling.
Nws compatibility nrog dej ua rau nws haum rau formulating ib puag ncig tus phooj ywg drilling kua.
8. Tshem tawm cov dej drilling:
Nyob rau hauv inhibitory drilling kua, HEC plays lub luag hauj lwm hauv kev tswj shale hydration, tiv thaiv kev nthuav dav, thiab txhim kho kev ruaj ntseg zoo.
9. Kub kub ib puag ncig:
HEC yog thermally ruaj khov thiab haum rau siv nyob rau hauv high-temperature drilling hauj lwm.
Nws cov khoom tseem ceeb yog qhov tseem ceeb rau kev tswj xyuas qhov ua tau zoo ntawm cov dej drilling hauv qhov kub thiab txias.
10. Additive compatibility:
HEC tuaj yeem siv ua ke nrog lwm cov kua dej ntxiv xws li polymers, surfactants thiab cov khoom hnyav kom ua tiav cov kua dej uas xav tau.
11. Shear degradation:
Shear ntsib thaum lub sijhawm drilling tuaj yeem ua rau HEC degrade, cuam tshuam rau nws cov khoom rheological dhau sijhawm.
Kev tsim kho thiab kev xaiv kom zoo tuaj yeem txo cov teeb meem cuam tshuam txog kev sib tw.
12. Kev cuam tshuam ib puag ncig:
Thaum HEC feem ntau suav tias yog ib puag ncig tus phooj ywg, tag nrho ib puag ncig kev cuam tshuam ntawm cov dej drilling, suav nrog HEC, yog lub ntsiab lus ntawm kev txhawj xeeb thiab kev tshawb fawb tsis tu ncua.
13. Tus nqi txiav txim siab:
Tus nqi-zoo ntawm kev siv HEC hauv cov kua dej drilling yog qhov kev txiav txim siab, nrog cov neeg ua haujlwm hnyav cov txiaj ntsig ntawm cov khoom ntxiv rau cov nqi.
nyob rau hauv xaus:
Nyob rau hauv cov ntsiab lus, hydroxyethyl cellulose yog ib qho tseem ceeb additive nyob rau hauv cov roj drilling kev lag luam, pab txhawb rau tag nrho cov kev vam meej thiab efficiency ntawm drilling hauj lwm. Nws muaj ntau yam kev ua haujlwm, suav nrog kev hloov kho rheology, kev tswj xyuas pom, kev tu lub qhov thiab lubrication, ua rau nws yog ib qho tseem ceeb ntawm cov dej drilling. Raws li kev ua haujlwm drilling txuas ntxiv mus txuas ntxiv thiab kev lag luam ntsib cov teeb meem tshiab thiab kev xav txog ib puag ncig, HEC tseem ua lub luag haujlwm tseem ceeb hauv kev ua kom pom kev ua tau zoo thiab kev ruaj khov ntawm kev lag luam roj drilling. Kev tshawb fawb txuas ntxiv thiab kev txhim kho hauv polymer chemistry thiab drilling kua tshuab yuav ua rau muaj kev nce qib ntxiv thiab txhim kho kev siv hydroxyethyl cellulose hauv kev lag luam roj thiab roj.
