Thawj ib qhov noj HD-1 ntawm qhov noj lub tsis muaj tebchaw
HD-1 yog cov lwm np tawv nyob rau lis thiab metal, thiab ntawm tau hais tau los-linear processing thiab ultra-fine spheroidization technology.
Tus txiv txwm yog 200~250 meshes, thiab tus ntsiab yog lub 7.4 thiab lub ntsiab thiab nyob rau li noj nrog li
tus barite weighting agent 4.6~5.05. Yog cov tawj ntawv ntsiab thiab txiv txwm qhia, thiab cov tawj ntawv ntsiab thiab txiv txwm qhia, thiab cov drilling fluid
weighting agent yog mus rau li cov kawm thiab tsis muaj rau li cov kawm thiab tsis muaj rau li cov kawm, thiab cov acidification rate yog paub 94.5%. Rau li cementing cement slurry, yog mus rau li cov dispersion thiab suspension thiab
ntawv nrog kev coob cement slurry mus yooj tawm 2.4~2.8g/cm3. Ntawv tau rau hais txhais ntawv kho, tsis muaj ib tug water-based mud lub tsis muaj ib tug oil-based mud yog kawm, thiab peb cai rauj li cas los ntawm weighting agent rooj ntsi.
