酸液增稠剂聚丙烯酰胺
酸化处理是油气田增产增注的主要措施之一， 它利用酸液对岩石胶结物或地层孔隙、裂缝内堵塞物的溶解和溶蚀作用，恢复或提高地层孔隙和裂缝的渗透性。酸液中加入性能良好的稠化剂，可提高酸液的粘度，降低活性酸扩散速度，增大酸液作用距离，延缓酸岩反应时间，增加裂缝的宽度，提高酸化效果，达到提高地层渗透率的目的。 Acidizing is one of the main measures to increase oil and gas fields.Using the principle of acid have corrosion and dissolution to rock cement,formation pore and fracture.Acidfication can restore or improve the permeability of the formation pore and fracture.The addition of acid thickener can improve the viscosity of acid,reduce the activity of acid diffusion velocity,increase acid operating distance,slow down the acid rock reaction time,increase the width of the cracks,improve the acidizing effect,achieve the goal of improve the formation permeability.
