| 摘 要： | 根据实验室岩心分析数据，通过对微观孔隙结构分析，讨论了高孔隙度低渗透率型碳酸盐岩储层测井电阻率、孔隙度、渗透率和含水饱和度之间关系的测井响应异常。具体分析了某孔隙型碳酸盐岩油气田B层油气藏的响应特征，从岩心分析资料建立的孔隙度渗透率交会图分析表明，B层的油气储性较差，与原测井响应的高孔隙度、高含油饱和度特征有比较大的差异。例举了数口井的应用实例。

| Abstract: | Based on core analysis data in lab and micro-pore structures, discussed are the abnormal log response relations among resistivity, porosity, permeability and water saturation in carbonate reservoirs with high porosity and low permeability. Actually analyzed are response characters of reservoir B in a porous carbonate oilfield. Porosity-permeability crossplot plotted from core analysis data indicates that the reservoir B is a poor not a high porous and high oil-saturated reservoir as the earlier log responses shown. Log examples of several wells are given. |
