摘要
针对胜坨油田开展了高温高盐油藏聚合物驱攻关研究和矿场先导试验。试验区包含32口注聚井,63口生产井。筛选了耐温抗盐性能较好的聚合物,利用数值模拟手段优化设计了科学合理的注入方案,先导试验投入矿场实施后,动态反应良好,取得了非常好的驱油效果:渗流阻力增加;注入压力上升4.1MPa;不同程度地改善了层间吸水状况;含水下降了14.3%;日油增加了1.33倍;已增产原油67.2×104t,提高采收率6.17%。
This paper studied the polymer flooding used in Shengtuo oilfield with high temperature and high salinity and carried out pilot test.Polymer tolerating high temperature and high salinity was screened.The polymer flooding injection scheme was optimized by numerical simulation method.Favorable effects have been acquired in the pilot test area.The injection pressure was risen by 4.1MPa,The flow resistance increased and the profile modified evidently in injecting wells.The oil production increased 1.33 times and the water cut decreased by 14.3% in producing wells.The incremental oil production was 67.2×104t and the enhanced oil recovery was enhanced by 6.17%.
