储层流体性质的测井判别是及时发现油气层的关键.川东北普光气田飞仙关组储层岩性、物性及孔隙结构复杂,属裂缝、孔洞多重储渗空间发育的储层,非均质性和各向异性严重,测井响应具多解性,导致利用测井资料判别储层流体性质的难度增大.从常规测井资料分析入手,从多种流体性质判别方法中优选了5种,在剖析其方法原理的基础上,探讨了各种方法在普光气田缝洞性储层的适用性,总结了一套适用于普光气田缝洞性储层特征的简便、合理的流体性质判别方法组合.

The well logging identification of reservoir fluid property is the key to determine hydrocarbon reservoir in time.Reservoir rocks,physical property and pore texture of Feixianguan Formation,Puguang gas field in northeastern Sichuan,are very complicated,the reservoir is the one with developed fracture and vug accumulative spaces and severe heterogeneity and anisotropy,well logging response is with multiple resolution,which makes identifying reservoir fluid property with logging data even more difficult.Started from conventional logging data analysis,five kinds of fluid property identification methods are optimally figured out,on the basis of analyzing the principles and methods,all kinds of suitable methods which can be used in fracture and cave reservoir in Puguang gas field are probed,a set of simple and reasonable identification method association suitable for the types of reservoirs are presented.
