【摘要】：为了解决现有压裂液防膨剂用量大、配伍性差、不便于现场配液等问题,室内实验研究合成了防膨率高、配伍性好的有机阳离子型液体防膨剂,同时确定了中间产物的最优反应物配比、反应温度和反应时间,以及终产物的最优配方。经评价,防膨剂质量分数为0.3%时,减阻水压裂液的防膨率为70.5%,且不影响压裂液减阻率。中试生产的防膨剂产品与现场市售同类商品相比,防膨率提高17%~33%,在新疆、重庆等现场进行了多井段的压裂施工,表现出优良的配伍性和防膨性,能满足压裂液防膨和连续混配要求。
[Abstract]:In order to solve the problems of large amount of fracturing fluid anti-swelling agent, poor compatibility and inconvenient for field distribution, an organic cationic liquid anti-swelling agent with high anti-swelling rate and good compatibility was synthesized in laboratory. At the same time, the optimum reactant ratio, reaction temperature and reaction time, and the optimum formulation of the final product were determined. The anti-swelling rate of drag-reducing water fracturing fluid is 70.5 and does not affect the drag reduction rate of fracturing fluid. Compared with the similar products sold on the spot, the anti-swelling rate of the pilot production is increased by 17% and 33% in Xinjiang. The fracturing operation of multi-well section was carried out in Chongqing and other fields, which showed excellent compatibility and anti-swelling, and could meet the requirements of anti-swelling and continuous mixing of fracturing fluid.
