| Complex polyol fluid52
|
It has been used in oil wells in the Gulf of Mexico, and the complex polyol fluid produced by the reaction of methyl glucoside and polyglycerol can improve the stability of the wellbore |
| Fatty alcohol53
|
Fatty alcohols can inhibit foam generation and reduce the impact on other properties of drilling fluids |
| Polyethylene glycol (PEG)10
|
PEG lubricant has no obvious effect on AV, PV, and YP of drilling fluid, and has been successfully applied in Sulige gas field |
| Polyaspartic acid (PA) and polyethylene glycol (PEG)54
|
The use of PA and PEG alone has little effect on the rheological properties of water-based drilling fluids. However, the combined use of PA and PEG has a synergistic effect on the rheology of the drilling fluid. In the presence of 10% PA, the addition of PEG increases the viscosity of drilling fluid but has little effect on PV and YP. The gel of the drilling fluid will increase with the increase of the PEG concentration, that is, the suspending ability of the drilling fluid will increase |
