Carboxymethyl cellulose sodium ntsev (CMC) rau cov kua drilling
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm peb cov ntsev carboxymethylcellulose sodium yog nws cov viscosity zoo heev thiab rheological zog. Nws muaj cov khoom zoo heev rau kev ncua thiab dispersion rau kev tswj hwm qhov zoo tshaj plaws ntawm cov kua dej ntws thiab siab thaum lub sijhawm drilling. Qhov no ua kom ntseeg tau tias kev ua haujlwm drilling du thiab ua haujlwm tau zoo, txo lub sijhawm downtime thiab nce kev tsim khoom.
Tsis tas li ntawd xwb, peb cov ntsev carboxymethyl cellulose sodium muaj cov yam ntxwv zoo heev rau kev tswj cov dej poob. Nws ua ib lub ncuav mog qab zib nyias nyias, tsis pub dej nkag rau ntawm qhov chaw khawb, ua kom cov kua dej hauv qhov chaw khawb tsis poob. Qhov no tsis yog tsuas yog ua kom lub qhov dej zoo xwb tab sis kuj pab txo qhov cuam tshuam rau ib puag ncig ntawm kev khawb.
Tsis tas li ntawd xwb, peb cov ntsev carboxymethyl cellulose sodium no tiv taus tau qhov kub thiab txias thiab qhov ntsev uas feem ntau tshwm sim hauv kev ua haujlwm drilling. Nws tseem ua tau zoo txawm tias nyob rau hauv qhov xwm txheej hnyav heev, ua kom cov kua drilling zoo ib yam thoob plaws hauv kev ua haujlwm.

Ntim thiab kev thauj mus los
Siv lub hnab yas uas muaj 25kg los yog lub hnab yas ntawv uas muaj daim ntaub qhwv. Kuj tseem tuaj yeem ntim tau raws li tus neeg siv xav tau. Thaum khaws cia thiab thauj mus los, xyuam xim rau kev tiv thaiv cua sov thiab dej noo, txheej txheej yuav tsum tsis pub tshaj 20 txheej. Lub sijhawm khaws cia zoo yog 2 xyoos.
Cov teeb meem xav tau kev saib xyuas:
Tsis txhob kom raug qhov muag, daim tawv nqaij thiab khaub ncaws, los yog yaug nrog dej ntau ntau. Khaws cia kom deb ntawm hluav taws.
1. Muaj hom tshuaj lom neeg twg siv rau hauv cov roj av?
Muaj ntau yam tshuaj lom neeg hauv cov roj av los daws cov teeb meem tshwj xeeb hauv kev lag luam roj thiab roj av. Cov tshuaj siv feem ntau suav nrog cov tshuaj tua kab mob, cov tshuaj tiv thaiv kev xeb, cov tshuaj demulsifiers, cov tshuaj tiv thaiv nplai, cov tshuaj txo kev sib txhuam, cov tshuaj surfactants, cov tshuaj emulsifiers thiab cov tshuaj acidifiers, thiab lwm yam.
2. Yuav ua li cas thiaj yuav tau cov tshuaj lom neeg hauv roj av?
Cov tshuaj lom neeg hauv thaj chaw roj av tuaj yeem yuav tau los ntawm cov chaw muag tshuaj uas muaj ntawv tso cai thiab tshwj xeeb hauv cov khoom tsim tshwj xeeb rau kev siv roj thiab roj av. Cov chaw muag khoom no feem ntau muaj cov pab pawg kws tshaj lij uas tuaj yeem qhia txog kev xaiv thiab siv cov tshuaj lom neeg tsim nyog raws li cov kev xav tau tshwj xeeb.
