摘要： 实验研究了三元复合体系对石英砂和耐碱树脂砂充填裂缝导流能力影响。结果表明,与弱碱相比较,强碱对石英砂溶蚀作用较强,颗粒破碎率较高,填砂裂缝导流能力降低幅度较大。与石英砂相比较,碱型对耐碱树脂砂溶蚀作用程度差异较小,对耐碱树脂砂填砂裂缝导流能力影响程度差异不大。随闭合压力增加,石英砂和耐碱树脂砂充填裂缝导流能力下降,但降低幅度逐渐减小。与石英砂相比较,闭合压力对耐碱树脂砂充填裂缝导流能力影响程度较小,裂缝导流能力较大。

Abstract: Influence of ASP system on the fracture conductivity of alkaliresistance resin sands and quartz sands was studied. The results showed that compared with the weak base, the dissolution of strong base on the quartz sands was more serious. And the damage percentage of the particles was higher. Therefore the reduction of conductivity of fractures packed with sands was larger. Compared with quartz sands, there was little difference between the dissolution of weak base on the alkaliresistance resin sands and that of weak base on the alkaliresistance resin sands. So it was the same to conductivity. With the increase of closing pressure, the conductivity of quartz sands and alkaliresistance resin sands were both weakened. But the reduction degree became gradually small. Compared with quartz sands, the influence of closing pressure on the conductivity of fractures packed with alkaliresistance resin sands was weak. And the fracture conductivity capacity was stronger.
