摘要
建立了人造胶结油藏模型三维物理模拟实验技术,用于研究渗流机理和提高采收率。这种油藏物理模型由环氧树脂密封,放置在大型压力舱中,系统实验压力可以达到3MPa,设计了50个测压点和40个电阻检测点,可以实时测定不同部位的压力和电阻率变化情况,2台电子天平用于计量产出液中的油水量。利用该实验系统和方法,可以长时间模拟饱和水、油驱水、水驱油等过程,并对油藏物理模型的动态数据和静态数据进行综合分析。
A series of petrophysical modeling experiment technologies is established, utilizing a large scale artificial consolidated model, to research the mechanisms of fluid flow in porous media and EOR. This petrophysical model was sealed by epoxy resin, and then placed into a large pressure cabin with maximum operation pressure of 3 MPa. Fifty pressure points and 40 resistance points were designed and arranged to detect and measure pressure and resistance value. Two electrical balances were utilized to record the yield fluids. This system can be controlled automatically by two computers. A long term test including modeling water saturating, displacement water by oil and displacement oil by water can be carried through with this system and technology.
