Cov tshuaj sib xyaw ua ke zoo rau cov kua dej drilling yog kev sib xyaw ntawm ntau yam polymers ntuj tsim, uas muaj dej zoo o thiab txuas lub zog kinetic ntawm cov kua dej, muaj zog lo rau, thiab tsis txwv los ntawm qhov sib phim ntawm cov khoom me me piv rau cov tshuaj sib xyaw ua ke. Thaum siv nrog ntau yam av nkos, nws tuaj yeem siv los kaw cov txheej txheej uas ploj lawm thiab tseem tiv thaiv cov txheej txheem tsim khoom qis-siab (roj, roj, dej, thiab lwm yam).

Kev Ua Haujlwm thiab Daim Ntawv Thov: 1. Nws muaj qhov ceev nrawm thiab muaj txiaj ntsig zoo rau cov qhov sib txawv thiab cov kab nrib pleb me me. 2. Nws tuaj yeem tsim cov siv tiv thaiv uas tsis nkag tau sai nrog lub zog tshwj xeeb los tiv thaiv kev nkag mus ntawm cov kua thiab cov khoom khov hauv cov kua ua haujlwm mus rau hauv lub pas dej, uas tuaj yeem tiv thaiv kev puas tsuaj rau lub pas dej. Cov siv tiv thaiv tuaj yeem tso tawm los ntawm kev tho qhov rov qab. 3. Nws tuaj yeem txo qhov kev lim dej ntawm cov av nkos yam tsis cuam tshuam rau nws cov khoom rheological, thiab muaj kev tiv thaiv kub zoo heev. 4. Tsis cuam tshuam los ntawm electrolyte contamination, tsis muaj tshuaj lom, thiab tsis muaj teeb meem.

1. Cov khoom siv roj hmab: Cov pa roj carbon dawb yog siv rau hauv cov khoom siv roj hmab xim los hloov cov pa roj carbon dub rau kev txhawb nqa, ua tau raws li qhov xav tau ntawm cov khoom dawb lossis semi pob tshab. Silica kuj muaj kev nplaum zoo heev, tiv taus kua muag, tiv taus kub thiab tiv taus kev laus, yog li nws kuj tuaj yeem hloov ib feem ntawm cov pa roj carbon dub hauv cov khoom siv roj hmab dub kom tau txais cov khoom siv roj hmab zoo, xws li cov log tsheb tawm ntawm txoj kev, cov log tsheb engineering, cov log tsheb radial, thiab lwm yam.

2. Cov khoom siv tshuaj lom neeg ua liaj ua teb: Hauv cov khoom siv tshuaj lom neeg ua liaj ua teb, xws li tshuaj tua kab, cov tshuaj chiv ua kom zoo, thiab lwm yam, cov pa roj carbon dawb siv ua tus nqa khoom, diluent, lossis disintegrant. Thaum siv ua disintegrant hauv cov hmoov dej dispersible (WDG), tus nqi suspension tuaj yeem nce ntxiv. Nws raug pom zoo kom siv cov ntsiab lus ntawm kwv yees li 10%. Nws tuaj yeem tswj tau qhov ua tau zoo ntev vim nws thaj chaw siab heev, muaj peev xwm nqus tau siab heev, suspension yooj yim, affinity zoo, thiab tshuaj lom neeg ruaj khov. Txawm tias nyob hauv nag, dej ntws, thiab kub, nws tuaj yeem nyob tsis hloov pauv ntev.

3. Cov khoom siv tshuaj lom neeg txhua hnub: Cov tshuaj txhuam hniav xim pob tshab thiab tsis pom tseeb nrog cov pa roj carbon dawb ua cov khoom siv thiab cov khoom siv abrasive. Hom tshuaj txhuam hniav no muaj kev ywj pheej zoo, yooj yim tawg, lub cev du thiab mos, tiv taus kev sib txhuam zoo, thiab tsis ua rau lub raj tshuaj txhuam hniav xeb; Nws tuaj yeem tswj tau qhov ruaj khov ntawm cov tshuaj txhuam hniav. Tshwj xeeb tshaj yog nrog kev sib raug zoo nrog fluoride, nws tuaj yeem zam qhov tsis zoo ntawm cov ntsev tsis yaj uas tsim los ntawm cov ntsev calcium ua cov khoom siv abrasive.

4. Cov nplaum: Siv rau hauv cov nplaum ua los ntawm roj hmab ntuj lossis roj hmab hluavtaws, nws muab thixotropy thiab kev txhawb nqa, thaum tseem txhim kho kev nplaum vim nws qhov kev nthuav dav, ua rau nws zoo thiab tsim nyog tus nqi.

5. Tus neeg sawv cev tiv thaiv kev sib sau ua ke: Cov pa roj carbon dawb tuaj yeem siv rau hauv qee yam khoom kom txhim kho kev ntws dawb, xws li cov chiv nyom, cov tshuaj tua kab mob, cov khoom sib tsoo log, cov tshuaj ntxhua khaub ncaws, phenolic txhaj tshuaj molding ntawm urotropine, cov khoom yas ntawm phenols thiab urea, kev tsim cov roj hmab sulfur thiab cov khoom sib xyaw tiv thaiv kev sib sau ua ke.

6. Cov khoom siv sau ntawv: Siv cov pa roj carbon dub dawb ua cov khoom siv sau ntawv tuaj yeem txhim kho qhov tsis kam ntawm cov kua mem thiab lub zog ntawm daim ntawv, ua kom dawb dua, thiab txo qhov hnyav ntawm daim ntawv. Nws tuaj yeem ua kom daim ntawv sib dua, txo cov nqi tsim khoom, thiab txhim kho kev ua haujlwm ntawm daim ntawv. Tsis tas li ntawd, nws kuj tseem siv tau rau ntau yam lag luam xws li cov neeg ua hluav taws, pub tsiaj, tshuaj pleev ib ce, cov neeg ua kom ploj mus, cov xim, xim pleev xim, thiab lwm yam.
