Hauv kev ua haujlwm drilling thiab tsim khoom, tsis yog dej-raws li av nkos nkaus xwb tab sis kuj tseem tuaj yeem npaj cov av nkos, thiab nws qhov kev ua tau zoo yog qhov zoo tshaj ntawm cov khoom hnyav hnyav.

Hauv kev drilling rau cov roj av, cov av nkos feem ntau yog siv los ua cov kua dej drilling. Feem ntau ua los ntawm kev siv cov khoom sib txuas xws li barite thiab bentonite av nplaum kom them tau lubricity zoo, kev tshawb fawb tau saib rau lwm cov ntaub ntawv uas yuav muaj txiaj ntsig thiab / lossis pheej yig dua - tab sis qhov tseem ceeb tshaj yog ua siab ntev rau kev kub siab, kub drilling txheej txheem niaj hnub no. Feem ntau rau cov ntawv thov no, cov khoom siv denser yog siv;

Cov ntawv thov tshwj xeeb ntawm cov hlau nplaum sib nqus hmoov hauv cov roj drilling muaj xws li:
1. Txhim kho kev ua haujlwm zoo drilling: Lub siab hlau nplaum thiab sib nqus conductivity ntawm cov hlau nplaum ntxhia hmoov ua kom nws zoo dua dispersed thiab tshem tawm hauv cov dej drilling, yog li txhim kho cov dej ntws thiab ruaj khov ntawm cov dej drilling thiab txo qhov kev pheej hmoo ntawm borehole phab ntsa vau.
2. Txo cov khoom hnav: Cov oxidation tsis kam thiab tshuaj lom neeg ruaj khov ntawm cov hlau nplaum ntxhia hmoov ua kom nws muaj kev ua haujlwm zoo nyob rau hauv qhov kub thiab txias ib puag ncig, thiab txo qhov hnav thiab corrosion ntawm cov khoom siv drilling los ntawm qhov kub thiab txias.
3. Txhim kho qhov kev ua tau zoo ntawm cov dej drilling: Los ntawm kev ntxiv cov khoom sib nqus hlau nplaum, qhov viscosity thiab ntom ntawm cov dej drilling tuaj yeem hloov kho kom tau raws li qhov xav tau ntawm qhov drilling nyob rau hauv cov xwm txheej sib txawv thiab txhim kho kev nyab xeeb thiab kev ua haujlwm ntawm kev ua haujlwm drilling.

Magnetite hmoov, uas yog, hmoov magnetite. Nws yog cov xim hlau nplaum ua los ntawm cov hlau tshauv thiab grey-dub, nrog cov xim muaj zog thiab zoo nkauj, huab cua tsis kam, corrosion kuj, acid kuj thiab muaj zog alkalinity.
