摘要
滑溜水可以有效降低管内摩阻,在非常规油气田开发中得到广泛应用。以快速增黏、抗高矿化度为核心,为了达到高矿化度返排水重复利用的目的,采用氧化还原体系引发丙烯酰胺(AM)、2-丙烯酰胺-2-甲基丙磺酸(AMPS)和二甲基二烯丙基氯化铵(DADMAC)水溶液进行三元共聚,得到速溶型快速增黏降阻剂。降阻剂性能测试结果表明:该降阻剂水溶性好,增黏速度快,降阻效率高达60%以上;30 000 mg/L矿化度模拟水下黏度保留率接近50%,降阻率仍在50%以上。
Slick-water is widely used in the unconventional oil and gas development due to its effective reduction in internal friction. To reuse the flowback water with high salinity,a resistance-reducing agent with rapid thickening property is synthesized by copolymerization of acrylamide（ AM）,2-acrylamido-2-methyl propane sulfonic acid（ AMPS） and dimethyl diallyl ammonium chloride（ DADMAC） in aqueous solution. The results show that the obtained resistancereducing agent has good solubility in water and rapid thickening property. The efficiency of reducing resistance is over60%. The retention rate of simulated flowback water with 30 000 mg / L of salinity is close to 50% with above 50% of resistance rate.
