摘要
特高含水期油田剩余油分布更加复杂，精细解释水淹层尤为重要。应用不同沉积微相的密闭取心井资料建立油、水相对渗透率与含水饱和度之间的关系，并将产水率划分水淹层标准转化为含水饱和度划分水淹层标准，分别建立了不同沉积微相水淹层解释标准，现场应用效果较好。新的解释标准可为测井解释、油藏模拟工程计算、射孔方案编制及油田开发分析调整方案提供依据。
At the stage of extra-high watercut, the distribution of remained oil in an oilfield is rather more complicated, so it is necessary to finely interpret the watered-out oil layers. By means of the data of pressure coring well, the change relations between oil/water relative permeability and water saturation are established. At the same time, the classifying standards of watered-out layers by water production ratio are changed into ones by water saturation, and furthermore the interpreting standards of watered-out oil layers with different sedimentary micro-facieses are separately set up, finally the field effects are proven much better. The new interpreting standards can provide an evidence for well logging interpretation, the calculation of reservoir simulation engineering, the compilation of perforation program and the analyses ＆ adjustment of oilfield development programs.
