摘要:
聚驱后油田剩余油分布更加分散,水流优势通道发育更加复杂,常规水驱洗油效率低。陆地油田常用的高浓度聚驱、二元/三元复合驱、热采等技术,在海上油田受到各种因素制约,无法大面积开展作业。为此,从扩大波及体积和提高洗油效率出发,提出堵调驱洗多段塞组合调驱技术。该技术既可以封堵纵向及平面水流优势通道,也可以提高洗油效率,从而提高采收率。数模研究及海上类似油田作业效果表明,堵调驱洗多段塞组合调驱技术降水增油效果优于单一的堵或者调驱洗注入方式。
Abstract:
After polymer flooding,the remaining oil distribution in the oilfields is more scattered,the development of water-flow dominant channels is more complicated,and the efficiency of conventional water flooding is low.The high-concentration polymer flooding, binary/ternary combination flooding, thermal recovery, and other technologies commonly used in land oilfields are restricted by various factors in offshore oilfields and can not be operated on a large scale.For this reason,starting from expanding the swept volume and improving the oil washing efficiency,it is proposed the multi-slug combination profile control and flooding technology.This technology can not only block the longitudinal and planar water-flow dominant channels,but also improve the oil washing efficiency,thereby increasing the recovery factor.Numerical simulation studies and similar offshore oilfield operations have shown that the multi-slug combination profile control and flooding technology has better water reduction and oil increase effects than a single plugging or control profile, flooding injection method.
