Tshawb nrhiav Cov Ntawv Thov Tseem Ceeb ntawm Polyacrylamide (PAM) hauv Cov Roj Drilling
Polyacrylamide (PAM) yog linear polymer nrog cov tshuaj formula (C₃H₅NO)n. Nws zoo nkaus li cov hmoov dawb los yog crystalline granules. Nws yog yooj yim soluble nyob rau hauv dej, thiab nws cov aqueous tov yog ib tug ze li pob tshab, viscous kua. PAM muaj cov flocculation zoo heev, adhesion, rub txo, thiab thickening zog.
PAM tuaj yeem muab faib ua peb hom raws li cov khoom ionic:
| Hom | Molecular Luj Range (10,000) | kho siab Degree | Siv tau pH Range | Cov yam ntxwv tseem ceeb |
| Anionic (APAM) | 300-2200 | 10-50% | 7-14 | Haum rau nruab nrab / alkaline ib puag ncig; thickening thiab flocculation muaj peev xwm |
| Cationic (CPAM) | 600-800 | 10-50% | 1-14 | Muaj zog nqi neutralization; zoo kawg nkaus decolorization thiab turbidity tshem tawm |
| Tsis yog -ionic (NPAM) | 500-600 | - | 1-14 | Haum rau acidic tej yam kev mob; zoo flocculation nyhuv |
Raws li "golden additive" nyob rau hauv oilfield chemistry, polyacrylamide qhia irreplaceable core tus nqi nyob rau hauv kom ntseeg tau tias drilling kev nyab xeeb thiab txhim kho cov roj rov qab.
Anionic Polyacrylamide: Tsim nyog rau qhov nruab nrab lossis alkaline ib puag ncig, nws yog qhov kev xaiv tseem ceeb rau cov dej ntws thiab cov roj xa tawm, muaj peev xwm thickening thiab flocculation zoo heev.
Kub- thiab ntsev-Resistant Hom: Rau qhov sib sib zog nqus zoo formations nrog kub thiab siab salinity, tshwj xeeb PAM derivatives muaj peev xwm tuav viscosity yam tsis tau txo, kom ua hauj lwm zoo nyob rau hauv hnyav geological tej yam kev mob.
Polyacrylamide, feem ntau hu ua "kev lag luam MSG" ntawm cov tshuaj oilfield, yog ib qho zoo tshaj plaws - muag khoom. Thov hu rau Henan Brilliant Biotech Co., Ltd. yog xav paub ntxiv.
