Galicia Water-In-Water Temperature And Salt-Resistant Polyacrylamide for Drag Reducer

maintained at 45° in a water-bath, to give a volume of 49.5 ml, adding 0.5 ml of am­ monium persulphate solution, 50 pI ofTEM ED, …

Oct 25, 2021 · In this experiment, 0.03% drag reducer was used as the experimental group, the slick water (2 L, containing P(AM-DHAB) 0.6 g) was put in 80 ℃ water bath, after the temperature of slick water rose to 80 ℃, 0.1 g ammonium persulfate was added, and the kinematic viscosity was measured at …

GALICIA IS WATER. Galicia is the number one hot springs destination in Spain. There are more than 300 hot springs in the region – making it one of the richest in Europe in terms of mineral and hot springs – that were used by the Romans. Our thermal spas have a long tradition as therapeutic, relaxation and leisure centres.

Dec 01, 2020 · MA Yingxian et al. / Petroleum Exploration and Development, 2020, 47(6): 1333–1341  1334  1. Design of a high salt tolerance and low adsorption drag reducer Currently, polyacrylamide-based drag reducers are com- monly used to prepare slick water.

While in brine, with a viscosity obviously lower than that in fresh water, the drag reduction rate was slightly lower than 70% when the concentration of drag reducer was 0.03%; increasing the ...
