苏伊士湾N油藏多轮次调驱物理模拟实验

Physical Simulation Experiment of Muti-Cycle Weak Gel Flooding in Suez-N Reservoir

弱凝胶深部调驱技术成熟、投资少、见效快,适合海外油田效益开发的要求。通过室内实验建立微观可视化模型和填充石英砂的平面可视化模型,模拟现场多方向见水的裂缝性或存在优势通道的N油藏进行多轮次调驱,并对多轮次调驱机理加以分析。结果表明,三轮次弱凝胶调驱可提高原油采收率29. 9%,可改善不同渗透率级差的吸水剖面,提高水驱效果。

Weak gel deep profile control technology is mature, less investment, quick effect, suitable for the development of overseas oil field requirements. This paper through the plane model visualization microscopic visualization model and filled with quartz sand, simulated multi direction water fractured reservoir or the existence of dominant channel for multi round mechanism of flooding. The experimental results show that the three times weak gel profile control flooding can improve the oil recovery by 28.9% , improve the water profile of different permeability, and optimize the water flooding effect.
