大港油田孔南地区水驱油仿真模拟实验

Simulation Experiment of Water Oil in Kongnan Region of Dagang Oilfield

水驱油后仍有大量的剩余油存在,这些剩余油对于提高油田产量起着至关重要的作用。以大港油田部分地区为例,按照沉积相带类型划分,制作驱替模型,对水驱后剩余油分布进行研究,总结出剩余油分布规律,进而对其进行推广。

After water displaces oil, there still exists a lot of oil in the layer, which is important to improve the yield. In the experiment, some formations in Dagang oilfield are taken as examples and displacing models are made according to the forms of sedimentary context. Then an analysis of the distribution of remaining oil and a sum - up of the distribution pattern of remaining oil are made.
