Polyacrylamide (PAM) rau Roj & Gas Exploitation

Polyacrylamide (PAM) yog siv dav hauv kev lag luam roj thiab roj rau ntau yam kev siv ntsig txog kev tshawb nrhiav, kev tsim khoom, thiab kev ua kom zoo dua qub. Cia peb tshawb xyuas seb PAM siv li cas hauv kev siv roj thiab roj:

1. Txhim Kho Roj Rov Qab (EOR):

• PAM tau ua haujlwm ua ib feem tseem ceeb hauv EOR cov tswv yim xws li dej nyab polymer. Nyob rau hauv cov txheej txheem no, PAM cov kev daws teeb meem yog txhaj rau hauv cov roj reservoirs los ua kom cov viscosity ntawm cov dej txhaj, txhim kho cheb efficiency, thiab tshem tawm cov roj seem ntawm lub pob zeb pob zeb.

2. Fracturing Fluids (Fracking):

• Hauv kev ua haujlwm hydraulic fracturing, PAM yog ntxiv rau cov kua fracturing los txhim kho viscosity, tshem tawm cov khoom siv, thiab tiv thaiv kom tsis txhob muaj dej poob rau hauv kev tsim. Nws pab tsim thiab tswj cov pob txha tawg hauv cov pob zeb reservoir, ua kom yooj yim rau kev khiav ntawm hydrocarbons mus rau lub qhov dej.

3. Drilling Fluid Additive:

• PAM yog ib qho tseem ceeb hauv cov dej drilling siv rau cov roj thiab roj qhov dej drilling. Nws ua raws li lub viscosifier, kua dej poob tswj tus neeg sawv cev, thiab shale inhibitor, txhim kho qhov ruaj khov, lubrication, thiab txiav tawm thaum lub sijhawm ua haujlwm drilling.

4. Flocculant rau kev kho dej khib nyiab:

• PAM yog siv los ua flocculant hauv cov txheej txheem kho dej khib nyiab cuam tshuam nrog kev tsim cov roj thiab roj. Nws pab hauv kev sib sau ua ke thiab daws cov khib nyiab tshem tawm, cov roj tee dej, thiab lwm yam kab mob, ua kom yooj yim rau kev sib cais ntawm cov dej kom rov siv dua lossis pov tseg.

5. Tus neeg saib xyuas Profile:

• Nyob rau hauv cov av loj hlob nrog dej los yog roj coning teeb meem, PAM yog txhaj rau hauv lub reservoir los txhim kho lub ntsug cheb efficiency thiab tswj cov dej txav nyob rau hauv lub reservoir. Nws pab txo cov dej los yog roj tawg thiab txhim kho cov roj rov qab los ntawm thaj chaw tsom.

6. Scale Inhibitor:

• PAM yog siv los ua cov nplai inhibitor los tiv thaiv kev tsim cov pob zeb hauv av xws li calcium carbonate, calcium sulfate, thiab barium sulfate hauv cov qhov dej ntau lawm, cov kav dej, thiab cov khoom siv ua haujlwm. Nws pab tswj kev ua haujlwm ntau lawm thiab ua kom lub neej ntev ntawm cov cuab yeej siv.

7. Emulsion Breaker:

• PAM yog ua hauj lwm raws li ib tug emulsion breaker nyob rau hauv crude roj dehydration thiab desalting txheej txheem. Nws destabilizes roj-hauv-dej emulsions, tso cai rau kev sib cais ntawm cov dej thiab roj theem thiab txhim kho qhov zoo ntawm cov roj crude.

8. Corrosion Inhibitor:

• Hauv kev tsim cov roj thiab roj, PAM tuaj yeem ua raws li kev tiv thaiv corrosion los ntawm kev tsim cov yeeb yaj kiab tiv thaiv ntawm cov hlau, txo tus nqi ntawm corrosion thiab ncua lub neej ntawm cov khoom siv thiab cov kav dej.

9. Cement Additive:

• PAM yog siv los ua ib qho ntxiv hauv cov cement slurries rau roj thiab roj zoo cementing ua haujlwm. Nws txhim kho cov cement rheology, txhim kho cov kua dej tsis zoo, thiab txo cov sij hawm cementing, ua kom muaj kev sib cais kom zoo thiab kev ncaj ncees.

10. Drag Reducer:

• Hauv cov kav dej thiab cov kav dej ntws, PAM tuaj yeem ua haujlwm ua lub luag haujlwm los yog kev txhim kho ntws, txo qis kev sib txhuam thiab txhim kho cov dej ntws zoo. Qhov no pab ua kom muaj peev xwm dhau los thiab txo cov kev siv zog siv zog.

Hauv cov ntsiab lus, Polyacrylamide (PAM) ua lub luag haujlwm tseem ceeb hauv ntau yam ntawm kev siv roj thiab roj, suav nrog kev txhim kho cov roj rov qab, hydraulic fracturing, drilling kua dej tswj, kev kho dej khib nyiab, kev tswj qhov profile, scale inhibition, emulsion breaking, corrosion inhibition, cementing, thiab flow assurance. Nws cov khoom siv ntau yam thiab ntau hom kev siv ua rau nws yog ib qho tseem ceeb ntxiv rau hauv kev lag luam roj thiab roj, pab txhim kho kev tsim khoom, kev ruaj ntseg ib puag ncig, thiab kev ua haujlwm.
