  • For the existence of hydrophobic group, the solubility of hydrophobically associate polymer becomes difficult, which is the bottleneck for widespreading polymer flooding in offshore oilfield. So it is necessary to study how to accelerate the solubility of hydrophobically associate polymer from technology. Laboratory experiments indicate that there is obvious division between the solubility and bulge of hydrophobically associate polymer. The crucial effect on its dissolution rate is how to fasten the molecular diffusion from the bulge to water. According to the Fick' s law, the overall dissolution rate of hydrophobically associate polymer is dominated by contact surface between the bulge and water. The smaller the bulge size, the quicker the dissolution. Experimental results show that the dissolution time is shorten by making the bulge granule overpassing screens under certain pressure. This method provides evidence for accelerating polymer dissolution for offshore oilfield.
