Cov yam ntxwv ntawm cov khoom ntawm txheej tus neeg sawv cev
Cov khoom no tuaj yeem raug ntxiv ncaj qha rau ntau yam dej-raws li drilling kua tshuab raws li txheej txheej inhibitor.Nws tuaj yeem siv ua ke nrog ntau yam kev kho dej drilling.
01
Tus neeg sawv cev txheej txheej 141 yog nplawm thiab sib npaug rau hauv lub tank dissolution kom tsis txhob siv cov nyhuv tshwm sim los ntawm kev tsim cov micelles uas tsis yooj yim rau yaj vim kev sib ntxiv ntau dhau ntawm ib zaug.
02
Qhia cov kua dej ua kua rau hauv qhov dej drilling circulaton system, thiab qhov ntau npaum li cas yog 0 2-0.5%.
03
Cov tshuaj soluble aqueous tsis tuaj yeem bestirred thiab tso rau lub sijhawm ntev.
04
Kev siv cov dej drilling los tiv thaiv kev sib tsoo
Cov additives yog sib xyaw rau hauv cov dej drilling los txhim kho lawv cov kev tiv thaiv kom tawg.
Txhim khu kev ruaj ntseg
Wellbore stability yog qhov tseem ceeb tshaj plaws uas yuav tsum tau ua kom zoo drilling. Thaum cov phab ntsa hauv lub qhov dej tawg lossis tawg, nws tuaj yeem ua rau muaj xwm txheej loj xws li kev poob ntawm kev ncig, cov kav dej daig, thiab cov tshuab tsis muaj zog. Txawm li cas los xij, cov tshuaj tiv thaiv kev sib tsoo txhim kho lub zog cohesive ntawm cov dej drilling thiab pab tiv thaiv phab ntsa ntawm lub qhov dej kom tsis txhob tawg.
Txo kev sib txhuam
Thaum drilling, nws yog ib qho tseem ceeb kom txo tau qhov kev sib txhuam ntawm lub laum me ntsis thiab lub qhov dej. Txij li thaum cov kua dej drilling yog cov roj nplua nyeem, cov khoom siv ntxiv xws li cov tshuaj tua kab mob tuaj yeem txhim kho cov khoom ntawm cov dej drilling thaum txhim kho lawv cov khoom thixotropic. Qhov no txo cov kev sib txhuam thiab pab kom nce qhov nkag mus.
Qhov zoo tshaj plaws av nkos kev ua haujlwm
Drilling kua yuav tsum muaj cov khoom tshwj xeeb uas tsim nyog rau drilling. Anticollapsing cov neeg ua haujlwm txhim kho kev ua haujlwm ntawm cov kua dej drilling, ua kom nws ua tau zoo dua hauv kev ua tiav nws lub hom phiaj. Cov khoom siv slurry zoo tshaj plaws tau ua tiav los ntawm kev siv cov tshuaj tiv thaiv kev sib tsoo muaj xws li tsis tshua pom, muaj peev xwm thauj khoom siab, kev pom zoo viscosity, siab yield point, thiab cov yas viscosity tsawg.
Txhim kho kev ua haujlwm zoo
Wellbore efficiency yog hais txog qib uas cov kev ua haujlwm drilling tuaj yeem nkag mus rau hauv qhov xav tau reservoir yam tsis muaj kev cuam tshuam. Anti-collapse agents txhim khu kev ruaj ntseg zoo, txo kev sib txhuam, thiab txhim kho av nkos kev ua tau zoo, tag nrho cov no pab txhawb kev txhim kho wellbore efficiency. Qhov no yuav pab kom ntseeg tau tias kev ua haujlwm drilling tau ua tau zoo, nyab xeeb thiab ua tau zoo.
