摘要
聚合物驱数值模拟中不可入孔隙体积和吸附滞留孔隙体积等物理化学参数往往不易准确获得,严重影响了聚合物驱数值模拟结果和矿场动态预测效果。该文以聚合物驱互溶驱替理论为基础,介绍了聚合物驱产出液浓度剖面模型的测定与分析方法。实验测得了大庆油层条件下的聚合物驱产出液浓度剖面模型,求出了相应的不可入孔隙体积和吸附滞留孔隙体积。通过浓度剖面模型确定不可入孔隙体积和吸附滞留孔隙体积的方法,具有操作简单、准确、易于掌握等特点。研究成果对聚合物驱数值模拟技术、聚合物驱方案设计和矿场动态监测有指导意义。
Results of polymer flooding numerical simulation and field dynamic prediction cannot be influenced severely because the physical-chemistry parameters of inaccessible pore volume and retention pore volume, which is necessary for polymer flooding numerical simulation, are difficult to obtain accurately. Based on the inter-miscible displacement theory of polymer flooding, the determination and analysis methods of effluent concentration profile model of polymer flooding have been presented in this paper. The effluent concentration profile model of polymer flooding in Daqing oilfield reservoir condition has been determined by experiment, and inaccessible pore volume and retention pore volume bas been obtained. The methods are simple, exact and easy to understand. The research achievements can be guidance for polymer flooding numerical simulation, project design and prediction of field test of polymer flooding.
