| 摘 要： | 针对黑油模型等效处理裂缝方法不能很好体现裂缝在油藏中的特性,利用裂缝-基质耦合渗流理论方法,建立油水两相三维裂缝性油藏数值模型。基于该数值模型研究油藏地质和开发条件对弱凝胶调驱效果的影响,对影响因素进行了显著性评价,通过对调驱影响显著的因素进行定量研究,提出了裂缝性油藏适宜调驱的油藏条件。利用正交分析方法,对实际油藏进行调驱参数优化设计。

| Abstract: | Due to the fact that the method of black oil model equivalent treatment fracture is unable to reflect the property of crack in the reservoir quite well, based on the theory of fracture-matrix coupling seepage, a 3D numerical model for oil-water two-phase fractured reservoir is established. By using the numerical model, the effect of different reservoir geology and development conditions on the weak gel modulation drive is researched, and the distinctiveness evaluation for the main influential factors is conducted, and the reservoir conditions for fractured reservoir appropriate flooding are put forward. By taking Jiangsu Oilfield as an example, the orthogonal analysis method is used to process the optimization design for real reservoir displacement parameters, the study results involving the utilization of weak gel modulation for fractured reservoir are able to improve recovery efficiency and have practical significance. |
