摘要：针对海上平台寿命有限、平台空间获小、聚驱产出液处理图难等特点，提出应用非均相调驱技术提高采收率的思路利用纵向三层非均质物理模型，考察了水驱后、聚整后、二元复合整后不同非均相体系驱油效果，结含替后常心剩余油分布情况，分新非均梅调驱与常规聚合物驱在驱油机理上的差异。研究结果表明：无论是水驱后、聚驱后、二元复合驱后，非均相调盟都能大幅度提高采收率，采收率增加值分别在6.95%、9.57%、11.46%以上；在相同浓度非均梅体系条件下，先溶张后注入和先注入后溶账2种不同注入方式驱油效果基本一致，说明体系在岩心内可以达到与内静态评价溶账相同的效果；分散相程径大小对于驱油效果的影响至关重要，大颗粒偏重于“调”，小短径偏重于“驱”。聚驱后油藏刺余油分布更加零散，进一步提高采收率的潜力主要在低渗造层，单纯依靠提高驱油体系的洗油效率不定以提高其动用程度，需要进一步扩大驱油体系的波及体积。

Abstraet: In view of limited offshore platform life, small space of platform and difficulty in treating the polymer flooding produced fluids, this paper introduces the idea of EOR using heterogeneous profile control and flooding technology. Using longitudinally 3-layer heterogeneous physical model, the oil displacement effects by different heterogeneous systems were investigated after water flooding, polymer flooding and SP flooding; in combination with remaining oil distribution in cores after displacement, the difference of hetero-geneous profile control and flooding and conventional polymer flooding was analyzed in oil displacement mechanism. Research results show that, the heterogeneous profile control and flooding can greatly enhance oil recovery after water flooding, polymer flooding and SP flooding, which enhance values are over 6.95%, 9.57% and 11.46% respectively. Under the heterogeneous system of the same con-centration, two injection methods injection after swelling and swelling after injection are almost the same in oil displacement effect, indicating that the system can achieve the same effect in cores as in indoor static evaluation swelling and that the particle size of disper-
