Hydroxyethylulose (HEC) plays Lub Luag Haujlwm Tseem Ceeb hauv kev lag luam roj drilling kev lag luam, tshwj xeeb tshaj yog nyob rau hauv cov kua dej lossis av nkos. Drilling kua yog qhov tseem ceeb nyob rau hauv cov roj dunring cov txheej txheem zoo, muab ntau cov haujlwm xws li txias thiab lubricating laum cov cuttings rau saum npoo av, thiab tswj kev ruaj ntseg kev ruaj ntseg. HEC yog qhov tseem ceeb ntxiv rau hauv cov kua dej drilling, pab txhawm rau txhim kho lawv cov kev ua tau zoo tag nrho thiab kev ua tau zoo.
Taw qhia rau hydroxyethyl cellulose (HEC):
1. Tshuaj Txhuam Cov Qauv thiab Khoom:
Hydroxyethyl cellulose yog qhov tsis muaj kev paub, dej-soluble polymer tau los ntawm kev hloov kho tshuaj ntawm cellulose.
Cov pab pawg hydroxyethyl nyob rau hauv nws cov qauv muab nws solubility hauv dej thiab roj, ua rau nws muaj ntau yam.
Nws cov molecular hnyav thiab cov qib hloov pauv rau nws cov khoom siv rheological, uas yog qhov tseem ceeb rau nws qhov kev ua tau zoo hauv cov kua drilling.
2.RHeological hloov kho:
HEC yog siv los ua cov rheology hloov kho, cuam tshuam rau kev coj tus cwj pwm ntws thiab viscosity ntawm drilling kua.
Kev tswj cov khoom ntawm rheological yog qhov tseem ceeb rau kev ua haujlwm zoo rau kev ua tau zoo ntawm cov kua dej hauv qis hauv cov kev mob sib txawv.
3. Lim tswj:
HEC Ua raws li cov neeg sawv cev pom kev, tiv thaiv cov kua ntau dhau los ua kev tsim.
Cov polymer ua cov lim lim nyias nyias, lub lim lim dej nyias nyias ntawm qhov chaw ua kua, txo cov kua dej kom qhuav rau hauv cov pob zeb loj.
4. Kev tu thiab dai:
Hec pab tshem tawm cov txiav txiav los, tiv thaiv lawv los ntawm kev tswm hauv qab ntawm qhov chaw nkaum.
Qhov no ua kom pom tseeb kev tu huv si huv si, ua kom muaj kev thaiv kom zoo thiab tiv thaiv kev thaiv uas tuaj yeem ua rau cov txheej txheem drilling.
5. Lubrication thiab cua txias:
Lubricating cov chaw ntawm HEC pab txo kev sib txhuam ntawm cov hlua laum thiab muaj kev nyab xeeb, yog li dhau los ntawm cov khoom siv drilling.
Nws tseem yuav pab cov cua sov dissipate, pab rau hauv qhov txias ntawm lub laum me ntsis thaum lub sijhawm ua haujlwm.
6. Tsim kev ruaj khov:
HEC Muab kev pab cuam kom zoo los ntawm kev txo qis kev pheej hmoo ntawm kev tsim kev puas tsuaj.
Nws pab tswj kev ncaj ncees ntawm kev tiv thaiv kev tiv thaiv los ntawm kev tiv thaiv kev vau lossis vau ntawm cov dav hlau ib puag ncig.
7. Dej-li Drilling FRLING:
Hec yog feem ntau siv nyob rau hauv dej-raws li drilling dej los ua kom tsis txhob muaj viscosity thiab ruaj khov rau cov kua drilling.
Nws cov kev sib raug zoo nrog dej ua rau nws haum rau cov qauv ua kom zoo ib puag ncig drilling kua.
8. Cugrappress Drilling FRLING:
Nyob rau hauv inhibitist drilling kua, Hec ua lub luag haujlwm hauv kev tswj cov dej ua ke, tiv thaiv kev nthuav dav, thiab txhim kho kev ruaj khov.
9. Ib puag ncig kub siab:
HEC yog thermally ruaj khov thiab haum rau siv nyob rau hauv qhov kev ua haujlwm kub-drilling.
Nws cov khoom yog qhov tseem ceeb los tswj cov txiaj ntsig ntawm kev khiav dej hauv qab cov kev mob siab.
10. Ntxiv compatibility:
HEC tuaj yeem siv ua ke nrog lwm cov dej lim dej ntxiv xws li cov polymers, surfactants thiab cov neeg sawv cev kom ua tiav cov kua dej uas xav tau.
11. Shear Demradation:
Shear tau ntsib thaum lub sijhawm khiav dej tuaj yeem ua rau HEC kom thuam, cuam tshuam nws cov khoom siv hluav taws xob dhau sijhawm.
Kev tsim kom zoo ntxiv thiab xaiv tau MIT cov kev cov nyom.
12. Ib puag ncig cuam tshuam:
Thaum HEc feem ntau suav nrog tus phooj ywg ib puag ncig, kev cuam tshuam tag nrho ntawm kev sib tsoo cov kua, nrog rau cov ncauj lus ntawm kev txhawj xeeb txuas ntxiv thiab tshawb fawb.
13. Kev Txiav Txim Siab:
Tus nqi-ua tau zoo ntawm kev siv HEC hauv cov kua dej yog qhov kev txiav txim siab, nrog cov neeg ua haujlwm hnyav ntawm cov nuj nqis ntawm cov nuj nqis.
Hauv kev xaus:
Hauv cov ntsiab lus, hydroxyethyl cellulose yog qhov muaj txiaj ntsig ntxiv hauv cov roj drilling kev lag luam, koom tes rau tag nrho kev ua tiav thiab kev ua haujlwm ntawm kev ua haujlwm drilling. Nws ntau lub zog, suav nrog Rheology kev hloov kho, kev tswj hwm pom, kev tu lubrication, ua rau nws ib qho kev sib xyaw ntawm cov kua dej sib xyaw. Raws li kev ua si drilling txuas ntxiv mus hloov dua tshiab thiab kev txiav txim siab ib puag ncig, HEC txuas ntxiv mus ua haujlwm tseem ceeb hauv kev ua haujlwm zoo thiab kev ruaj khov ntawm cov haujlwm roj. Kev tshawb fawb txuas ntxiv thiab Drilling cov kua roj polymer thiab drilling txuas ntxiv thiab txhim kho hauv kev lag luam hydroxyethyl cellulose hauv cov roj thiab roj kev lag luam.
