性质:压裂是用压力将地层压开,形成裂缝,并用支撑剂将它支撑起来,以减小流体流动阻力的增产、增注措施。压裂过程用的液体叫压裂液。一种好的压裂液应满足下面要求:黏度高,便于携带支撑剂(如石英砂);在泵送过程中摩阻要低;防滤失性好;压后破胶和返排迅速;而且要经济可行,不伤害地层。压裂液主要有两大类,即水基压裂液(water-base fracturing fluid)和油基压裂液(oil-base fracturing fluid),最先采用的是油基压裂液。目前,95%的压裂液采用水基压裂液,油基压裂液仅占5%。压裂液中还可加入各种添加剂来提高压裂液在高温下的黏度,降低其低温下的黏度,或控制向地层内的滤失。
