Drilling av nkos polyacrylamide (PAM) muaj ntau yam kev siv, tshwj xeeb tshaj yog nyob rau hauv cov roj extraction thiab drilling txheej txheem. Hauv qab no yog cov kev siv tseem ceeb ntawm PAM hauv cov av nkos, nrog cov lus piav qhia ntxaws raws li cov ntaub ntawv los ntawm cov khoom siv:
Tackifier:PAM tuaj yeem siv los ua tus tackifier txhawm rau txhim kho cov roj rov qab thaum lub sijhawm cov roj rho tawm thiab cov txheej txheem drilling. Los ntawm kev ua kom cov viscosity ntawm cov av nkos drilling, PAM pab kom zoo dua nqa thiab tshem tawm cov drill cuttings, ua kom lub qhov dej huv thiab txo qhov kev pheej hmoo ntawm qhov dej vau thiab cov yeeb nkab daig.
Flocculation:Raws li kev kho dej polymer flocculant, PAM tuaj yeem nqus cov khoom tshem tawm hauv dej thiab tsim cov khoom siv polymer ntawm cov khoom, uas yog qhov hu ua "adsorption bridging". Cov nyhuv no pab cov khoom zoo tsim cov flocs loj dua thiab ua kom cov sedimentation tus nqi, yog li txhim kho kev sib cais thiab rov ua haujlwm ntawm cov av nkos.
Resistance txo:PAM tuaj yeem txo qhov kev sib txhuam ntawm cov kua dej zoo. Ntxiv cov lej ntawm PAM rau hauv dej tuaj yeem txo qhov tsis kam ntawm cov dej ntws, uas yog qhov tseem ceeb rau kev siv dej thiab kev ncig ntawm cov av nkos, pab txo kev siv hluav taws xob thiab txhim kho kev ua haujlwm drilling.
Kev ruaj ntseg:PAM muaj kev ruaj ntseg zoo nyob rau hauv ib txwm muaj, tsis yooj yim oxidized thiab decomposed, thiab tsis yooj yim cuam tshuam los ntawm acid thiab alkali tej yam kev mob. Qhov kev ruaj ntseg no ua kom muaj txiaj ntsig ntev ntawm PAM hauv cov av nkos drilling thiab txo qhov kev pheej hmoo ntawm kev ua haujlwm los ntawm kev ua tsis tiav ntxiv.
