Viscosifier rau cov kua drilling (80A51)
Cov khoom no yog dawb los yog daj daj dawb ntws hmoov, yog cov khoom siv polymer viscosity enhancer.
Cov khoom no muaj peev xwm tiv taus qhov kub thiab txias siab tshaj 120 ℃, qhov viscosity ntawm cov kua drilling tuaj yeem nce mus txog ntau dua 25mPa.s nrog tsuas yog 0.3% ntxiv, uas tuaj yeem txhim kho thixotropy thiab chip carrying peev xwm ntawm cov kua drilling. Tib lub sijhawm, cov khoom no kuj tuaj yeem siv ua tus neeg sawv cev txo cov kua dej poob.

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.
