摘　　要：全面模拟油藏实际条件,对轮南古潜山碳酸盐岩油藏进行了衰竭驱替物理模拟实验。在国内首次人工制造出了同时符合油藏储渗层渗流空间形态要求和渗透率要求的网状裂缝(洞)岩心,并在四高,即压力高、温度高、矿化度高、粘度高的模拟油藏实际条件下成功应用人工制造网状缝岩心完成了轮古地区长岩心驱替实验。实验结果为确定轮南古潜山碳酸盐岩油藏岩石物理特性、流体性质及驱油速度对驱油效率(采收率)的影响提供了有效的实验支持和实验基础数据。The physical simulation test for depletion drive in carbonate reservoir in Lunnan buried hill is conducted according to the real reservoir conditions of modeling. The domestic artificial map cracking （cavity） core is first presented, which is accordant with prerequisites similar to the real permeability and the percolation spatial configuration of the reservoir, and successfully applied to the long-core test under the conditions of high pressure, high temperature, high salinity and high viscosity available. The test results as basic experimental data have effectively supported the investigations for determination of effects of the petrophysical property, the fluid property and the displacement rate on the oil displacement efficiency in this carbonate reservoir.
