A study of numerical simulation of water alternating gas injection fo r condensate gas reservoirs 凝析气藏水气交替注入数值模拟研究
2.
It performs a large amount of physical simulation experiment using the multi - function displacement equipment which is imported from american temco company and summarizes the effecting rule of the injected alternating slug size on the displacement efficiency during the alternating injection of gas and liquid . it uses orthogonal method to study the set and type of pre - slug and post - slug and their effect on the displacement efficiency of foam flooding and optimizes the main and sub - slug size so as to decrease the cost while keeping a high displacement efficiency 通过从美国temco公司引进的多功能驱替设备，所做的大量的物理模拟试验，总结出了气液交替注入时，注入交替段塞的大小对驱油效率的影响规律，利用正交设计法研究了前后段塞的设置与否及种类对泡沫复合驱驱油效率的影响程度，还对主次段塞的大小进行优化，在保证较高的驱油效率的前提下降低成本。
