Koj rau hloov tawm mus lawv daim ntawv, lub mud ntawm hais tias noj ntau yuav ua li cas drilling fluid. Yog mus ua hauv compounds los barite thiab bentonite clays rov yog cov tsis muaj nyob qhia, kws kho tau txog cov neeg khw tsis tuaj yeem thiab/ho tuaj cheeb - yog ib tug qhia yog mus ua hauv high pressure, high temperature drilling processes ntawd. Yog mus ua hauv applications tias, cov neeg hais tias sib ob mob yog ua li;

Cov txheej kev cai magnetic mineral powder rau hloov tawm mus lawv daim ntawv yog:
1. Thiaj cov hluav hluav: Nyob hais tias high magnetism thiab magnetic conductivity ntawm magnetic mineral powder, noj ntau yuav ua li cas dispersion thiab suspension rau hloov tawm mus lawv daim ntawv, yog thaum mus ua li cov fluidity thiab stability ntawm drilling fluid thiab tham hais tias risk borehole wall collapse yuav paub.
2. Tsis txhawb qhov rooj kev cai: Roj tshwm cov tsis ntawm qab ntsiav thiab rauj hauv koom nrhiav thiab koom cas tias no yog ib tug qhia li cas los yog tau, suav los yuav tsum mus rau qhov rooj kev cai tshiab thiab ua siab tebchaws rau lwm tswv xwb.
3. Suav los yuav tsum mus rau qhov cas drilling: Rau muaj lub tswv hauv nyob, cov cas drilling yuav tsum ua hauj hais los yuav tsum mus rau cas viscosity thiab density cas drilling los yog tau, ua hauj hais los yuav tsum mus rau cas drilling tshaj ntawd thiab suav los yuav tsum mus rau cas drilling operations.

Rog npe yog ib tug cov tsis muaj hauv npawb: rau hauv high gradient magnetic separation, magnetite nanoparticles tau tagaub hauv cov nyob qhov tswj ntawm, thiab mus ua hauv lawv tswj ntawm (muaj solids, bacteria, noj yog plankton, tsis txog), thiab mus ua hauv lub kawg ntawm ntawm hauv lub fluid, yuav tsum mus tau tso nug cov contaminants thiab tau tso nug cov magnetite particles mus ua hauv lwm thiab ua hais.
