摘　　要：研制了由 0 .0 6 %～ 0 .2 %的增粘悬浮剂、0 .0 8%～ 0 .14%的有机复合交联剂和 0 .0 2 %～ 0 .0 4%的结构调节剂等组成的PT2 1可动凝胶调驱剂。室内实验和矿场试验表明 ,该调驱剂不仅能够封堵注水井的高渗透层段 ,起到剖面调整、改善注入流体的渗流作用 ,而且在后续水驱过程中具有良好的运移行为 ,并可对层内剖面实现动态调整 ,达到提高波及面积的目的。该调驱剂使用方便 ,效益高 ,具有良好的应用前景。PT21 movable gel profile control-displacement agent is developed that is compos e d of 0.06%～0.2% viscosifying suspending agent, 0.08%～0.14% organic compound cr osslinker and 0.02%～0.04% structural correctives etc. Lab and field experiments show that this agent not only can plug the high-permeability formations of wat e r injector to control the profile and improve the seepage flow of injected fluid but also has good migration in the process of succeeding waterflooding, can rea lize dynamic setting for the profile in place to achieve the goal of improving t he sweep area. This agent is easy to operate with high benefit and good prospect in application.
