In consideration of startup pressure effects, the water displacing oil process under a combination of multiple layers with different permeability has been modeled. 考虑启动压力的影响,对不同渗透率储层在多层组合条件下的驱替进行模拟研究;
The main factors affecting single layer displacement can be determined by water displacing oil experiments through long cores, providing a foundation for numerical simulations. 通过长岩心水驱油实验,确定影响单层驱替效果的主要因素,为数值模拟研究提供参数取值依据;
Study on Phisical-chemical and Performance Properties for YTF-1 Aircraft Water Displacing(WD) Corrosion Preventive Compound with Hard Film YTF-1飞机硬膜脱水防锈剂理化性能和使用性能研究
In the experiment, Water displacing oil with three types of finger, mesh and uniform shape. 实验中微观水驱油形态有指状、网状和均匀状三种类型,其中均匀状较少见,以网状型和指状水驱油为主,驱油效率低。
Surfactants can improve the water displacing oil efficiency by about 10 %. 表面活性剂能够提高此类储层的微观水驱油效率10%左右。
