Cov Tshuaj Ntxiv Rau Cov Kua Drilling | HEC, CMC, PAC

Cov tshuaj ntxiv rau cov kua dej drilling, suav nrog HEC (hydroxyethyl cellulose), CMC (carboxymethyl cellulose), thiab PAC (polyanionic cellulose), yog cov khoom tseem ceeb siv hauv kev lag luam roj thiab roj av los txhim kho kev ua haujlwm ntawm cov kua dej drilling. Nov yog kev faib tawm ntawm lawv lub luag haujlwm thiab kev ua haujlwm:

1. HEC (Hydroxyethyl Cellulose):
   • Kev Tswj Qhov Ntswg: HEC yog ib qho polymer uas yaj tau hauv dej uas feem ntau siv los ua ib qho kev hloov pauv viscosity hauv cov kua dej drilling. Nws pab ua kom qhov viscosity ntawm cov kua dej, uas yog ib qho tseem ceeb rau kev nqa thiab dai cov txiav drilling, tshwj xeeb tshaj yog nyob rau hauv cov qhov dej ntsug lossis deviated.
   • Kev Tswj Xyuas Kev Poob Dej: HEC kuj tseem tuaj yeem ua haujlwm ua tus neeg sawv cev tswj kev poob dej, txo qhov poob ntawm cov kua dej drilling rau hauv lub hauv paus. Qhov no pab tswj kev ruaj khov ntawm lub qhov dej thiab tiv thaiv kev puas tsuaj rau lub hauv paus kim.
   • Kev Ruaj Ntseg Kub: HEC ua kom pom tseeb tias qhov kub thiab txias zoo, ua rau nws tsim nyog siv rau hauv qhov chaw kub thiab txias tsawg.
   • Ib puag ncig tus phooj ywg: HEC yog biodegradable thiab tus phooj ywg ib puag ncig, ua rau nws yog ib qho kev xaiv zoo rau kev siv hauv cov kua dej drilling, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam rhiab heev rau ib puag ncig.
2. CMC (Carboxymethyl Cellulose):
   • Viscosity Modifier: CMC yog lwm yam polymer uas yaj tau hauv dej uas feem ntau siv los ua viscosity modifier hauv cov kua drilling. Nws pab txhim kho cov khoom rheological ntawm cov kua, txhim kho nws lub peev xwm nqa thiab kev ncua ntawm cov txiav drilling.
   • Kev Tswj Xyuas Kev Poob Dej: CMC ua haujlwm ua tus neeg sawv cev tswj kev poob dej, txo kev poob dej rau hauv qhov chaw thiab tswj kev ruaj khov ntawm lub qhov dej thaum lub sijhawm ua haujlwm drilling.
   • Kev kam rau ntsev: CMC ua kom pom kev kam rau ntsev zoo, ua rau nws tsim nyog siv rau hauv cov kua dej drilling hauv cov dej ntsev lossis qhov twg muaj ntsev ntau.
   • Kev Ruaj Ntseg Thermal: CMC muaj kev ruaj ntseg thermal zoo, uas ua rau nws tswj tau nws cov kev ua tau zoo txawm tias nyob rau hauv qhov kub siab uas ntsib hauv kev ua haujlwm tob tob.
3. PAC (Polyanionic Cellulose):
   • Muaj Viscosity Siab: PAC yog ib qho polymer uas muaj molecular hnyav thiab muab viscosity siab rau cov kua dej drilling. Nws pab txhim kho lub peev xwm nqa tau ntawm cov kua dej thiab pab txhawb kev ncua ntawm cov txiav drilling.
   • Kev Tswj Xyuas Kev Poob Kua: PAC yog ib qho tshuaj tswj kev poob kua zoo, txo cov kua poob rau hauv qhov chaw tsim thiab tswj kev ruaj khov ntawm lub qhov dej.
   • Kev Ruaj Ntseg Kub: PAC muaj kev ruaj ntseg kub zoo heev, ua rau nws tsim nyog siv rau hauv qhov chaw khawb av kub siab, xws li kev khawb av tob lossis geothermal.
   • Kev puas tsuaj tsawg ntawm kev tsim kho: PAC tsim ib lub ncuav mog qab zib nyias nyias, tsis nkag tau rau ntawm qhov chaw tsim kho, txo qhov kev pheej hmoo ntawm kev puas tsuaj ntawm kev tsim kho thiab txhim kho kev tsim khoom ntawm lub qhov dej.

Cov tshuaj ntxiv rau cov kua dej hauv qhov av no, suav nrog HEC, CMC, thiab PAC, ua lub luag haujlwm tseem ceeb hauv kev ua kom zoo dua ntawm kev ua haujlwm hauv qhov av los ntawm kev tswj cov khoom ntawm cov kua dej, txo qhov puas tsuaj ntawm cov av, thiab ua kom lub qhov av ruaj khov. Lawv txoj kev xaiv thiab kev siv nyob ntawm cov xwm txheej tshwj xeeb ntawm qhov av, xws li cov yam ntxwv ntawm cov av, qhov tob ntawm qhov av, qhov kub thiab txias, thiab qhov ntsev.
