Polyanionic cellulose (PAC) Polymers ua si ib lub luag haujlwm tseem ceeb hauv cov dej lim dej, ua haujlwm ntxiv rau kev txhim kho cov kua thiab ua kom zoo tshaj drilling kev ua haujlwm.
1. Speetroduction rau Dej-Raws Li Drilling Dej:
Dej-raws li drilling kua, tseem hu ua Muds, yog qhov tseem ceeb hauv kev lag luam drilling rau ntau yam. Lawv pab nyob rau hauv lub txias thiab nqus lub laum me ntsis, nqa cov laum me ntsis, khaws cov chaw ruaj khov, thiab tiv thaiv kev puas tsuaj. Ntawm cov ntau ntau cheeb tsam ntawm drilling kua, polymers zoo li PAC ua lub luag haujlwm tseem ceeb hauv kev ua tiav cov kua thiab ua tau zoo.
2.characteristics polyanionic cellulose (PAC) polymers:
Polyanionic cellulose yog dej-soluble polymer muab tau los ntawm cellulose, muaj cov khoom muaj txiaj ntsig uas ua rau nws zoo tagnrho rau cov ntawv thov drilling. Qee tus yam ntxwv tseem ceeb ntawm PAC polymers muaj:
Dej solubility: PAC cov pa dej polymer ua kom muaj dej sib xyaw ua ke, tso cai rau kev tshem tawm tau yooj yim thiab ua kom muaj kev sib xyaw ua dej npau npau.
Viscosity tswj: lawv pab txhawb kev tswj hauv cov kua dej drilling, ua kom cov kua kom nqa cov cais txiav kom zoo thiab tswj kom muaj kev ruaj ntseg zoo.
Kev tswj cov kua dej: PAC polymers ua raws li kev tswj cov roj ua kua dej zoo, ua kom muaj cov roj sib khuam kom tiv thaiv kom tsis txhob muaj dej.
Thermal Stability: cov polymers muaj cov khoom ruaj khov hluav taws xob, tswj lawv cov txiaj ntsig ntawm kev ua haujlwm kub thaum lub sijhawm khiav haujlwm.
Kev sib thooj: PAC polymers tau sib xws nrog lwm cov tshuaj ntxiv ntxiv siv hauv cov kua dej sib ntxiv, xws li cov pob txha, thiab lub roj hnyav.
3.functions ntawm PAC polymers hauv dej-raws li drilling dej:
PAC polyments pab ntau lub zog hauv cov dej-raws li drilling dej, pab txhawb kev ua kua tag nrho thiab ua haujlwm tau zoo:
Viscosity Transpification: Los hloov kho cov concentration ntawm PAC polymers, lub viscosity ntawm cov khoom siv drilling tuaj yeem ua kom tau raws li cov yam ntxwv. Tsim nyog viscosity tswj kev ua kom pom kev zoo thauj khoom thiab muaj kev ruaj khov ruaj khov.
Kev tswj cov dej: PAC polymers tsim ib qho nyias nyias, low-priceability lim ncuav mog qab zib rau ntawm phab ntsa zoo, ua kom txo cov kua dej zoo rau hauv kev tsim. Qhov no pab tswj hwm hydostatic siab, txo qis kev tsim kev tsim kho, thiab txhim kho kev ua haujlwm.
Rheology tswj: PAC polymers cuam tshuam lub rheological cov yam ntxwv ntawm cov kua dej drilling, suav nrog cov lus taw tes, gel lub zog, thiab ntws tus cwj pwm index. Kev ua kom zoo dua Rheology ua kom cov haujlwm du zom cov haujlwm thiab tswj kev sib tw ua tau zoo av nkos.
Kev Tu: Kev siv PAC polymers tau txhim kho los ntawm kev ncua thiab thauj cov laum txiav tawm mus rau sab nrauv kom zoo. Qhov no tiv thaiv kev sib txuam nyob rau hauv qab ntawm lub qhov, txo txoj kev pheej hmoo ntawm cov yeeb nkab daig thiab lwm yam kev phom sij drilling.
Lim ncuav mog qab zib zoo: PAC polymers pab rau qhov tsim ntawm lub tshuab lim dej muaj txiaj ntsig zoo nrog cov khaub noom zoo nkauj nrog cov khaub ncaws zoo nkauj thiab qis. Ib qho khoom noj muaj zog lim zoo muab cov kev tiv thaiv zoo kom zoo thiab txo kev tsim kev puas tsuaj.
4.Benefits ntawm PAC polymers hauv kev ua haujlwm drilling:
Kev koom tes ntawm PAC polymers rau hauv cov dej lim dej muaj ntau cov txiaj ntsig uas txhim kho kev ua kom haum, muaj kev ua haujlwm zoo nkauj:
Txhim kho lub qhov ruaj khov: PAC polymers pab tswj kom muaj kev sib zog kom zoo los ntawm kev tswj cov kua dej poob thiab kev tsim kev tsim kom tsawg. Qhov no txo qhov kev pheej hmoo ntawm kev sib tsoo ntawm kev poob siab, daig yeeb nkab, thiab lwm yam teeb meem drawing.
Kev Txhim Kho Cov Ncauj Hluav Taws Xob: Los ntawm kev ua kua dej zoo li cov roj ntsha ua kom nruj nrawm, ua rau muaj kev kub ntxhov thiab txo cov nqi ua haujlwm.
Tsim kev tiv thaiv: kev tsim cov lim dej zoo nrog PAC cov pa roj polymers tiv thaiv kev tsim cov dej ntawm cov kua dej los ntawm kev sib raug zoo. Qhov no yog tshwj xeeb yog qhov tseem ceeb nyob rau hauv cov kev tsim tawm muaj kev puas tsuaj.
Qhov kub kub kuj: PAC cov polymer tso hluav taws xob thermal stability, tuav lawv cov txiaj ntsig txawm tias thaum nce qhov kub tau ntsib ib puag ncig tob. Qhov no ua kom pom tseeb cov kua dej thiab kev ntseeg siab tau raws li cov kev mob nyuaj.
Kev sib xyaw uas muaj puag ntsig: dej-raws li drilling cov kua muaj pac polymers muab cov tshuaj tiv thaiv roj pev-raws li kev lom zem, thiab siv tau yooj yim dua thiab pov tseg.
Polyanionic cellulose (PAC) polymers yog indispensable additives hauv dej-ua ntau yam kev siv drilling efficiency, muaj kev ncaj ncees, thiab ib puag ncig kev ruaj ntseg. Lawv cov khoom tshwj xeeb thiab kev ua kom muaj cov kua dej viscosity, txo kev tiv thaiv, thiab kev tsim kom haum, thiab kev tsim kho kom zoo.
