Hauv cov kua dej drilling, PAC yog hais txog polyanionic cellulose, uas yog ib qho tseem ceeb uas siv rau hauv cov av nkos drilling. Cov av nkos drilling, tseem hu ua cov kua dej drilling, ua lub luag haujlwm tseem ceeb hauv cov txheej txheem drilling ntawm cov roj thiab cov qhov dej roj. Nws ua haujlwm ntau yam, xws li txias thiab lubricating cov khoom siv drilling, thauj cov txiav mus rau saum npoo, muab kev ruaj khov ntawm lub qhov dej, thiab tswj kev siab ntawm cov dej.
Polyanionic cellulose yog ib qho polymer uas yaj tau hauv dej uas tau los ntawm cellulose, ib qho polymer ntuj uas pom muaj nyob rau hauv cov nroj tsuag. PAC raug ntxiv rau cov kua dej drilling kom txhim kho lawv cov rheology thiab kev tswj kev lim dej.
1. Cov qauv tshuaj lom neeg thiab cov khoom ntawm polyanionic cellulose (PAC):
PAC yog ib qho cellulose polymer hloov kho nrog cov nqi anionic.
Nws cov qauv tshuaj ua rau nws yooj yim soluble hauv dej, tsim cov tshuaj ruaj khov.
Qhov xwm txheej anionic ntawm PAC pab txhawb rau nws lub peev xwm los cuam tshuam nrog lwm cov khoom hauv cov kua drilling.
2. Cov khoom rheological zoo dua:
PAC yog siv los hloov kho cov khoom rheological ntawm cov kua dej drilling.
Nws cuam tshuam rau viscosity, gel zog thiab kua dej poob tswj.
Kev tswj cov rheology yog qhov tseem ceeb rau kev ua kom zoo dua ntawm kev thauj mus los ntawm kev txiav thiab tswj kev ruaj khov ntawm lub qhov dej.
3. Kev tswj lim:
Ib qho ntawm cov haujlwm tseem ceeb ntawm PAC yog tswj cov kua dej poob thaum lub sijhawm ua haujlwm drilling.
Nws ua ib lub ncuav mog qab zib nyias nyias, tsis nkag tau rau ntawm phab ntsa qhov dej, tiv thaiv kev poob ntawm cov kua dej drilling rau hauv qhov chaw.
Qhov no pab tswj cov khoom xav tau ntawm cov av nkos drilling thiab tiv thaiv kev puas tsuaj rau cov qauv.
4. Kev ruaj khov ntawm lub qhov dej:
PAC pab txhawb rau kev ruaj khov ntawm lub qhov dej los ntawm kev tiv thaiv cov kua dej ntau dhau kom tsis txhob nkag mus rau hauv qhov tsim.
Nws pab txo qhov sib txawv ntawm qhov dej txhaws thiab lwm yam teeb meem cuam tshuam nrog kev tsis ruaj khov ntawm lub qhov dej.
Kev ruaj khov ntawm lub qhov dej yog qhov tseem ceeb rau kev ua tiav ntawm kev ua haujlwm drilling.
5. Hom PAC thiab lawv daim ntawv thov:
Muaj ntau qib sib txawv ntawm PAC nyob ntawm qhov hnyav molecular thiab qib ntawm kev hloov pauv.
Cov PACs viscosity siab feem ntau yog siv qhov twg xav tau kev tswj hwm rheology siab tshaj plaws.
Rau cov ntawv thov uas qhov kev tswj cov kua dej poob yog qhov tseem ceeb, PAC viscosity qis yuav raug nyiam dua.
6. Kev xav txog ib puag ncig:
PAC feem ntau suav hais tias yog ib puag ncig zoo vim nws yog biodegradable.
Kev ntsuam xyuas qhov cuam tshuam rau ib puag ncig tau ua tiav los xyuas kom meej tias kev siv thiab pov tseg cov kua dej uas muaj PAC muaj lub luag haujlwm.
7. Kev tswj xyuas thiab kev sim zoo:
Muaj kev tswj xyuas zoo nruj heev kom ntseeg tau tias PAC ua haujlwm tau zoo hauv cov kua dej drilling.
Muaj ntau yam kev ntsuam xyuas, suav nrog kev ntsuas rheological thiab kev ntsuam xyuas kua dej poob, tau ua los ntsuam xyuas kev ua haujlwm ntawm cov av nkos drilling uas muaj PAC.
8. Cov teeb meem thiab kev tsim kho tshiab:
Txawm hais tias nws siv dav dav los xij, tej zaum yuav muaj teeb meem xws li kev ruaj khov ntawm thermal thiab kev sib haum xeeb nrog lwm cov khoom siv ntxiv.
Kev tshawb fawb thiab kev tsim kho tshiab tas mus li yog mob siab rau kev daws cov teeb meem no thiab txhim kho kev ua tau zoo ntawm PAC hauv cov kua dej drilling.
Polyanionic cellulose (PAC) yog ib qho tseem ceeb hauv cov kua dej drilling thiab pab tswj kev rheology, kev tswj kev lim dej thiab kev ruaj khov ntawm lub qhov dej. Nws cov yam ntxwv tshwj xeeb ua rau nws yog ib qho khoom siv tseem ceeb hauv kev lag luam roj thiab roj drilling, ua lub luag haujlwm tseem ceeb hauv kev ua tiav thiab kev ua haujlwm zoo ntawm kev drilling.
