摘要

研究聚合物驱有效控制时间范围及其影响因素

有利于聚合物驱后进一步提高采收率措施的开展。结合水驱油藏的特征曲线理论和聚合物驱流度控制作用机理建立了判断方法

并通过室内驱油实验进行了影响因素的分析。结果表明

聚驱前后的水驱特征曲线存在一定的差异。随着后续水驱过程的进行

其水驱规律会逐渐回归到聚合物驱前的原有规律

将聚合物驱前后水驱特征曲线规律的一致性作为判断聚合物驱有效流度控制范围的方法是可行的。增加聚合物溶液黏度对其流度控制时间的影响相对较小

仅有10-2数量级注入PV量的影响;增加残余阻力系数能大幅度延长聚合物驱的有效流度控制时间

达到10-1数量级注入PV量的影响。聚合物的残余阻力系数是影响有效流度控制时间范围的主要因素。

Abstract

The study on the effective control time range of polymer flooding and its influencing factors is conducive to the further development of oil recovery measures after polymer flooding. Based on the theory of characteristic curve of water flooding reservoir and the mobility controlling mechanism of polymer flooding

a judgment method was established

and the influencing factors were analyzed through the indoor flooding experiments. The results showed that there were some differences in the water flooding characteristic curves before and after polymer flooding. With the follow-up process of water flooding

its rule would gradually return to the original rule before polymer

flooding. It was feasible to judge the effective mobility control range of polymer flooding by the consistency of the characteristic curve of water flooding before and after polymer flooding. The effect of increasing the viscosity of polymer solution on its mobility control time was relatively small

only 10

-2

order of magnitude of PV injection. Increasing the residual resistance factor（RRF） could significantly prolong the effective mobility control time of polymer flooding

and reached 10

-1

order of magnitude of PV injection. The residual resistance coefficient of polymer is the main factor affecting the effective mobility control time.
