Petroleum qib carboxymethyl cellulose (cmc) yog qhov tseem ceeb siv tshuaj rau hauv cov roj thiab roj kev lag luam, tshwj xeeb hauv cov kua dej drilling. Kev tsim qauv "LV" sawv ntsug rau "Qis viscosity," qhia tias nws lub cev tshwj xeeb lub cev thiab haum rau cov ntawv thov tshwj xeeb tsis pub dhau cov roj av rho tawm thiab kev ua.
Muaj pes tsawg leeg thiab cov khoom ntawm cov roj av qeb CMC-LV
Carboxymethyl cellulose yog dej-soluble polymer muab tau los ntawm cellulose, lub ntuj polymer pom nyob hauv tsob ntoo cell phab ntsa. Qhov "tsis tshua muaj viscosity" variant muaj cov khoom tshwj xeeb, suav nrog cov khoom hnyav hauv qab, uas txhais ua cov nyhuv qis dua thaum yaj hauv dej. Qhov no ua rau nws zoo tagnrho rau cov ntawv thov uas yuav tsum tau hloov tsawg dua hauv cov kua viscosity.
Cov yam ntxwv tseem ceeb:
Solubility: siab solubility nyob rau hauv dej, floilitating yooj yim tov thiab xa tawm nyob rau hauv drilling kua.
Thermal ruaj khov: tswj kev ua haujlwm ncaj ncees nyob rau hauv kev kub siab ntsib thaum lub sijhawm khiav.
Ph kev kam: ruaj khov thoob plaws qib pH ntau, ua rau nws ntau yam rau cov chaw sib txawv.
Tsis tshua muaj viscosity: tsawg cuam tshuam rau lub viscosity ntawm lub hauv paus dej, qhov tseem ceeb rau kev siv drilling tshwj xeeb.
Kev Siv Cov Roj Meum Qib CMC-LV
1. Cov kua dej
Thawj qhov kev siv ntawm roj av qeb CMC-LV yog nyob rau hauv cov qauv ntawm cov kua dej, tseem hu ua av nkos. Cov kua no yog qhov tseem ceeb hauv cov txheej txheem drilling rau ntau yam:
Lubrication: Drilling kua cov roj ntub lub laum me ntsis, txo kev sib txhuam thiab hnav.
Cua txias: Lawv pab txias lub laum me ntsis thiab cov hlua laum, tiv thaiv kev kub ntxhov.
Kev tswj cov cua siab: DRILLING FEMWS muab hydrostatic siab los tiv thaiv cov tshuab raj thiab kom ruaj khov.
Txiav tshem tawm: Lawv thauj Laum txiav rau saum npoo, tswj txoj kev ntshiab rau kev drilling.
Nyob rau hauv cov ntsiab lus no, lub viscosity qis ntawm CMC-LV kom ruaj khov thiab tuaj yeem ua tiav cov haujlwm tuab heev lossis gelatinous kev ncig thiab drilling kev ua haujlwm thiab drilling efficiency.
2. Cov kua dej ploj
Kev tswj cov kua dej yog qhov tseem ceeb hauv kev ua haujlwm drilling kom tiv thaiv kom tsis txhob muaj cov kua drilling rau hauv kev tsim. Petroleum Qib CMC-LV ua raws li kev tswj cov kua dej los ntawm kev sau ib qho khoom qab zib, tsawg-permeability lim ncuav mog qab zib rau ntawm phab ntsa. Qhov kev txwv no minimizes lub infiltration ntawm drilling cov kua rau hauv cov chaw puag ncig, yog li khaws cia qhov zoo thiab tiv thaiv kev puas tsuaj.
3. Txhim Kho Mob Borehole Stability
Los ntawm kev koom tes rau kev tsim ntawm lub lim lim ruaj khov, CMC-LV pab tswj hwm borehole stability. Nov yog qhov tshwj xeeb tshaj yog qhov tseem ceeb tshaj plaws uas tsis muaj peev xwm rau qhov tsis muaj zog lossis vau. Lub lim ncuav mog qab zib txhawb nqa phab ntsa zoo thiab tiv thaiv kev phom sij lossis kev pheej hmoo qeeb ntawm kev ua haujlwm qeeb thiab cov nqi ntxiv uas cuam tshuam nrog borehole intability.
4. Corrosion Inhibition
Petroleum Qib CMC-LV tseem tuaj yeem ua lub luag haujlwm hauv kev tiv thaiv corrosion. Los ntawm kev tswj cov kua dej poob thiab tswj cov chaw ruaj khov nyob hauv qhov chaw nyab xeeb, CMC-LV pab tiv thaiv cov khoom siv drilling los ntawm kev tsim cov kua dej. Qhov no txuas lub neej ntawm cov khoom siv drilling thiab txo cov nqi txij nkawm.
Cov txiaj ntsig ntawm kev siv roj av qeb CMC-LV
1. Kev ua haujlwm ua haujlwm
Kev siv CMC-LV hauv cov kua dej drilling tseem ceeb pab txhim kho kev ua haujlwm. Nws cov viscosity qis ua kom cov kua tsis muaj roj thiab ua tau zoo nyob rau ntau qhov kev puas ntsoog, yooj yim rau kev ua haujlwm smoother.
2. Nqi-ua hauj lwm
Los ntawm kev tiv thaiv cov kua dej poob thiab tswj kom muaj kev ruaj khov muaj kev ruaj khov, cmc-lv pab txo lub sijhawm thiab cov nqi cuam tshuam. Nws txo qhov kev xav tau rau cov ntaub ntawv ntxiv thiab kev cuam tshuam los daws cov kua dej poob lossis borehole insetability, ua rau muaj kev txuag nqi.
3. Ib puag ncig cuam tshuam
Petroleum Qib CMC-LV yog muab los ntawm cellulose, lub ntuj thiab txuas ntxiv dua. Nws siv hauv cov dej khiav tawm tuaj yeem pab txhawb kev ua haujlwm ib puag ncig drilling. Ib qho ntxiv, cov dej tau zoo tswj tau kom txo qhov peev xwm rau kev sib kis ib puag ncig los ntawm cov kua dej tsis sib xws los ntawm kev tsim.
4. Txhim Kho Kev Nyab Xeeb
Tswjhwm kev nyab xeeb kom ruaj khov thiab tswj cov kua dej tsis tseem ceeb rau kev ua haujlwm drilling. CMC-LV pab tiv thaiv kom tsis txhob muaj txoj kev npau taws, thiab lwm yam xwm txheej txaus ntshai, kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab khoom siv.
Cov ntawv thov tshaj li cov kua dej
Thaum thawj daim ntawv thov cov roj av qeb CMC-LV yog nyob rau hauv cov kua tho, nws muaj lwm cov kev siv hauv kev lag luam roj av thiab dhau mus.
