cov khoom piav qhia
Lub shale tsim reagent yog cov kua tshwj xeeb lossis cov khoom ntxiv tsim los txo cov teebmeem ntawm shale thaum lub sijhawm drilling. Nws npog cov khoom shale thiab tiv thaiv lawv los ntawm kev nkag mus rau hauv cov kua dej drilling, txo txoj hauv kev ntawm txoj hlua tho thiab kev poob. Shale txheej cov neeg ua hauj lwm kuj tuaj yeem pab tswj lub qhov dej zoo thiab txhim kho cov tub ntxhais rov qab.
Muaj ntau hom shale txheej neeg ua hauj lwm muaj, xws li av nplaum stabilizers, surfactants, thiab polymers. Lub luag haujlwm ntawm av nplaum stabilizers yog los tiv thaiv cov dej ntawm cov av nplaum thiab txo cov plasticity thiab o ntawm shale. Surfactants yog siv los rhuav tshem qhov nro thiab txo qhov adhesion ntawm shale thiab drilling kua. Lub polymer tsim ib zaj duab xis tiv thaiv uas tsim ib qho kev thaiv ntawm cov dej drilling thiab cov shale. Qee cov shale formation reagents yog tsim rau cov shale formations.
Xaiv txoj cai shale txheej tus neeg sawv cev yog ib qho tseem ceeb heev vim hais tias sib txawv shale formations muaj cov khoom sib txawv. Piv txwv li, shale formations nrog cov av nplaum siab yuav tsum tau siv cov av nplaum stabilizers. Hloov pauv, shale formations nrog siab salinity yuav tau txais txiaj ntsig los ntawm kev siv cov surfactants. Shale txheej cov neeg ua hauj lwm yuav tsum tau sib xws nrog cov dej drilling siv.
Txoj kev thov
Sediment txheej inhibitors feem ntau yog ntxiv rau cov kua dej drilling hauv daim ntawv ntawm cov kua, uas yog thauj mus rau hauv qab ntawm lub qhov dej thiab coated rau ntawm phab ntsa zoo los ntawm kev ncig ntawm cov dej drilling.
Thaum ntxiv cov inhibitors, qhov tsim nyog tus nqi thiab cov txheej txheem ntawm kev ntxiv yuav tsum tau txiav txim siab raws li cov yam ntxwv xws li lub ntim ntim ntawm cov dej drilling, qhov tob tob, tsim cov yam ntxwv, thiab lwm yam.
