摘要: 采用岩心分流驱替实验装置,研究了泡沫对单一含油岩心、含水岩心的封堵能力以及对不同渗透率级差含油、含水并联岩心的分流能力。结果表明,在单一泡沫驱替岩心实验条件下,泡沫具有封堵叠加的作用;而在并联岩心驱替实验条件下,泡沫不仅对含油、含水岩心具有选择性,而且对高、低渗透率岩心也具有选择性。泡沫具有较好的选择性暂堵分流效果,适用于非均质地层。

Abstract: A series of core divided-flow experiments were carried out on the core divided-flow displacement set.The foam plugging ability of single oil-saturated core and hydrous core as well as the foam divided-flow ability of parallel oil-saturated core and hydrous core were analyzed.The single core displacement experiments indicated that the foam has the accumulating and plugging effects,and the parallel cores experiments revealed that the foam has divided-flow selectivity not only in the parallel cores of oil saturation and water saturation,but also in the parallel cores of different permeability.Foam has favorable selective divided-flow performance,and the foam plugging technology fits to increase oil production of heterogeneous formation.

Key words: foam selective divided-flow, plugging technology, heterogeneous formation, core divided-flow displacement experiment
