摘要
以田菁胶、磨芋胶、多聚甲醛和凝胶增强剂为主要原料 ,合成新型的无固相凝胶定时堵剂NSG - 2。实验研究了NSG - 2的合成条件 ,并对其性能进行了评价。结果表明 :该堵剂通过控制合成条件 ,能在漏层部位定时堵隔和解堵 。
NSG-2 solid-free gel timing plugging agent is prepared with sesbania gum, paraformaldehyde and gum extender as main materials. The preparation conditions and performance of NSG-2 is studied and evaluated through experiment. The result is that, this material can timely plug and unplug leaking horizon through controlling preparation conditions. It is good to reservoir protection.
