摘要:
针对海上高含水油田常规聚合物驱面临的注采能力下降和波及效率受限等问题,开展了非连续化学驱注采能力变化规律的实验研究。通过岩心驱替实验、二维平板物理模拟和数值模拟等方法,揭示了非连续注入方式的动态响应特征及作用机制。研究结果表明:①对海上高含水油田采用非连续化学驱技术,通过“高浓度封堵-低浓度驱替”的段塞协同作业,实现了储层内部驱替压力的分布优化,低渗透层采出程度提升了8.4%,高渗透层采收率提高了7.4%。②非连续注入方式显著提升了注采能力,高浓度段塞注入阶段的吸水指数下降了4.18%,低浓度段塞注入阶段的吸水指数上升了14.41%,整体上升了5.12%。③浓度梯度调控有效改善了波及效率,低渗透层吸液量增加了3.6%,增强了不同渗透层段的同步运移程度。④数值模拟结果验证了非连续注入方式的有效性,实验中重构储层压力场与流场的分布,通过非连续化学驱技术的应用,有效抑制了原油黏度衰减和“油墙”形成,其“封堵-导流”协同机制可实现海上高含水油田均衡驱替和高效开发。
