目前国内油田压裂施工所采用的稠化剂天然聚合物和人工合成聚合物体系压裂液,大部分为高分子聚合物,这种压裂液具有抗剪切性好、热稳定性好、水不溶物和破胶残渣含量较低、控制滤失能力强等诸多优点。然而也存在很多不足,本文将针对聚合物压裂液性能的影响因素及改进策略进行研究。
At present, the domestic thickener natural polymer and synthetic polymer system fracturing fluid used in oilfield fracturing are mostly high polymer. The fracturing fluid has good shear resistance, good thermal stability, Insoluble matter and plastic broken residue content is low, the ability to control the loss of filtration and many other advantages. However, there are still many shortcomings. In this paper, the influencing factors on the performance of polymer fracturing fluid and the improvement strategies will be studied.
