摘要(Abstract)：

目前,流动单元研究在砂岩油藏研究中已得到广泛应用,但对于缝洞型碳酸盐岩油藏来说,由于成岩后生作用、构造断裂作用、溶蚀作用等多种因素对储集空间的综合影响,使砂岩油藏的流动单元研究方法难以直接应用于缝洞型碳酸盐岩油藏。因此,针对塔河油田缝洞型碳酸盐岩地质特征,论证了该区碳酸盐岩储层渗流屏障的存在及其类型,探索性提出区别于砂岩油藏的缝洞型碳酸盐岩储层流动单元的综合研究方法,包括油藏压力趋势分析法和流体性质分析法等,并综合缝洞型储层的发育特征初步划分了该区的缝洞型碳酸盐岩流动单元。
At present,flow units study has been widely applied in sandstone reservoir study.But conventional theory of flow units is difficult to apply to fracture-cavity carbonate reservoir,due to complex influence of post-diagenesis,tectonic fracturing and dissolution.Based on typical geological features of fracture-cavity carbonate reservoir in Tahe Oilfield,the existence and variance of seepage barrier is discussed and proved.Systematic study methods of flow units in fracture-cavity carbonate reservoir which is quite different from that of sandstone reservoir is brought forward,including pressure trend analysis,inter-well production interference analysis,fluid PVT differences,interference well test.Combining with reservoir features discussed above,the primary standard of flow units of fracture-cavity carbonate reservoir in this area is established.
