Development and Test of a Temperature-resistant Salt-resistant Gelling Polymer Profile Control Oil Displacement System

耐温抗盐交联聚合物调驱体系的研制与试验

During ausform finishing process of hardened gears, there is plastic displacement of metal on the tooth surface and the distortion of tooth profile.

在齿轮热滚挤加工中，轮齿上的金属在强制挤压力的作用下沿齿面产生塑性流动，使齿形发生变化。

Synthesis and Performance Evaluation of Super Water-absorbent Granular Gel Profile Control and Displacement Agent

超强吸水颗粒型凝胶调驱剂的合成与性能评价

The result shows that, compared with polymer flooding, polymer cross link micro gel has more remaining amount in multi porous, poor mobility and high injection pressure, so it has a nice profile controlling displacement effect.

实验结果表明，与聚合物驱相比，由于聚合物交联微凝胶在多孔介质内滞留量大，流动能力差，注入压力高，因而调驱效果好。
