Description

两亲高分子和用途
技术领域
本发明涉及一种两亲高分子及其用途,该两亲高分子适用于油田钻井、固井、压裂、原油集输、污水处理、污泥处理和造纸等领域,可用作强化采油驱油剂、稠油降粘剂、压裂液、粘土稳定剂、污水处理剂、造纸用助留助滤剂或补强剂等。
背景技术
化学方法是重要的强化采油提高原油采收率(Enhanced Oil Recovery,EOR)技术,而以聚合物驱为代表的化学驱是其中最有效和具潜力的措施之一。然而,随着聚合物驱技术的深入实施,常规驱油用聚合物体系凸显出一些问题。举例来说,广泛使用的部分水解聚丙烯酰胺聚合物在高温高盐油藏条件下增粘能力、热稳定性迅速降低,同时其本身不具有表面/界面活性,不能有效启动油膜,挖掘剩余油的能力有限。而以聚合物为基础的二元复合体系(聚合物/表面活性剂)和三元复合体系(聚合物/表面活性剂/碱)增强了原油采出液的乳化稳定性,导致油水分离和污水处理难度增大,同时在油藏条件下容易造成组分间协同作用减弱的问题,并可能对油藏造成伤害。复合体系的应用因而受到很大限制。
稠油开采是世界范围内的共同难题,其主要原因是稠油具有粘度大、胶质沥青质或含蜡量高的特点,在地层、井筒及输油管线中不易流动,另外由于油水流度比大,还易造成油井见水快、采出液含水率高、地层易出砂等问题。稠油开采方法主要可分为注入流体开采(如热水驱、蒸汽吞吐、蒸汽驱等)和增产型开采方式(如水平井、复合分支井、电加热等)。化学降粘剂对于稠油可进行有效分散、乳化等作用,显著降低稠油粘度、减小稠油在地层和井筒中流动阻力,这对于降低开采过程能耗、减少排放污染、提高稠油采收率具有重要意义。

测定实施例
测定例1
使用矿化度3×104mg/L的盐水配制不同浓度的两亲高分子溶液,测定溶液浓度、温度与溶液粘度的关系,结果见图1和图2。
图中表明,在高温和高矿化度条件下,实施例1-5的两亲高分子溶液仍具有良好的增粘能力。两亲高分子中的高空间位阻单元减小了主链内旋转自由度、增加了大分子链的刚性,使大分子链难于蜷曲而趋向伸展,导致大分子流体力学半径增大,同时,两亲结构单元通过分子内或分子间作用形成缔合微区,显著提高了高温高盐条件下的溶液增粘能力。
测定例2
测试方法:温度为25℃下,将三种油田电脱原油样品25ml加入50ml具塞试管中,继续加入25ml以蒸馏水配制的不同浓度两亲高分子的水溶液,盖紧试管塞后,采用手工方式振荡或将试管放置在振荡箱内,水平振荡80-100次,振幅应大于20cm,充分混合后,松动试管塞。原油降粘率按照下式计算:

表1实施例6-实施例10制得的两亲高分子稠油降粘实验结果(油水比1∶1,25℃)
Figure BDA0000078610300000191
表1说明,实施例6-10的两亲高分子对于三种油样具有很好的降粘效果。随两亲高分子溶液浓度增加,降粘率增大。溶液浓度相同时,油样粘度提高则相应降粘率增大。两亲高分子通过高空间位阻单元与两亲结构单元的协同作用,有效乳化、分散原油,显著降低了原油粘度。
