Oil &Gas exploitation
PAMs have been widely applied in oil drilling industry :
1. EOR(tertiary oil recovery)
Enhace
oil recovery (tertiary oil recovery): this requires the high molecular
weight PAM with high viscosity . Ordinary product can resist a
temperature up to 75℃ and a salinity up to 30,000 ppm. Salt-tolerant
products can resist a temperature up to 90℃ and a salinity up to 30,000
ppm.
| Product name | Product appearance | Molecular weight(million) | Ionic charges (%) | Dissolution time(min) | Solid content (%) | Charge type |
| FA series | White granular | 8-30 | 20-35 | ＜60 | ＞90 | Anionic |
2. DRILLING FLUID PAM
In drilling fluid ,PAM is applied to adjust clay swelling , dilution of bentonite ,etc.
| Product name | Product appearance | Molecular weight (million) | Ionic charges (%) | Dissolution time(min) | Solid content (%) | Charge type |
| FA series | White granular | 3-20 | 20-40 | ＜60 | ＞90 | Anionic |
| AFE series | Emulsion | 8-20 | 20-40 | ＜30 | 35-45 | Anionic |
3. PROFILE- MODIFYING /WATER SHUTOFF AGENT
Drilling conformation : to increase the oil production while reducing the water out-coming .
| Product name | Product appearance | Molecular weight(million) | Ionic charges (%) | Dissolution time(min) | Solid content (%) | Charge type |
| FA series | White granular | 8-20 | 20-40 | ＜60 | ＞90 | Anionic |
4. Oily waste water treatment
PAM can used to separate the oil and the water .
| Product name | Product appearance | Molecular weight(million) | Ionic charges (%) | Dissolution time (min) | Solid content (%) | Charge type |
| FA series | White granular | 8-20 | 20-40 | ＜60 | ＞90 | Anionic |
5． DRAG REDUCTION AGENT
High molecular weight PAM with medium ion-degree could obviously reduce the frictional resistance in the transmitting tubes.
| Product name | Product appearance | Molecular weight(million) | Ionic charges (%) | Dissolution time (min) | Solid content (%) | Charge type |
| FA series | White granular | 3-20 | 20-40 | ＜60 | ＞90 | Anionic |
| AFE series | Emulsion | 8-20 | 10-30 | ＜30 | 35-45 | Anionic |
