摘　　要：普光气田目的层段飞仙关组-长兴组海相碳酸盐岩地层发育气层,储层类型以孔隙-孔洞型为主,局部发育裂缝。针对这些储层特征,参考地质资料、微电阻率扫描成像资料,总结出了利用常规测井资料识别储层储集空间类型的方法;并在碳酸盐岩储层孔隙度参数求取中,采用光电吸收截面指数(Pe值),准确确定储层中岩性成分,为求取孔隙度参数提供了保障;在识别储层流体性质方面,通过实践经验总结出了交会图法、纵横波速度比值法等多种识别流体的方法,同时在核磁共振资料识别流体性质方面也做了大量的工作,在实际生产中显示出了很好的应用效果。Puguang gas field has gas reservoir in Feixianguan Group and Changxing group,which is the interesting formation of carbonate zone.The main storing type is pore-vug,some of it has cracks.Aimming at these reservoir characteristics,consulting information of Geology and micro-resistivity imaging data,the method of identifying reservoir space type is available through conventional logging information.In the course of processing porosity parameters of carbonate reservoir,Pe value is used to accurately determinate lithological composition.In the aspect of identifying the nature of reservoir fluid,interpretation chart,vpvs value and so on is used effectly.At the same time NMR data supplies valuable information.The effect is demonstrated to be very well in the actual production.
