摘要
由于聚合物的抗盐能力较差, 在较高矿化度配聚水和较高矿化度地层条件下, 聚
合物溶液的黏度难以保持, 影响了聚合物驱的波及能力和驱替效果。采用一种具有螯合作用
的聚合物增稠保黏剂, 在配聚时加入, 可提高聚合物驱替液的抗盐能力, 使聚合物溶液在较高
矿化度的地层条件下, 黏度也可得到保持, 从而使波及能力和驱替效果得以保证。
Abstract
Conventiona l Po lym er ( .i e. , HPAM ) has a poo r saltres istance capac ity. If w ate r is prepared w ith the h igher sa lin ity for w ater flooding and the salin ity is h igher in the form ation, the v iscosity of po lym er is usua lly not easy to be kep t, resu lting in a poo r sweep effic iency and displac ing effect. This paper propo ses a novel po lym er th icken ing and v iscosity stab iliz ing agent hav ing a strong che la tion. W hen the prepared po lyme r is injected into the fo rma tion, the saltres istance capac ity of the po lym er disp lac ing flu id is im proved, wh ile the v iscosity of po lym er so lution is constant even under the form ation w ith higher sa linity. Thus, it mainta ins the sw eep effic iency and d isplacing effect o f the po lyme r
