中文摘要：

利用测井资料确定有效储层物性下限并识别隔挡层,结合岩性—岩相等定性分析方法和聚类—判别等定量分析方法综合识别相邻隔挡层间连通火山岩体内的储层流动单元.以岩心和测井资料为基础,用孔隙度、渗透率、声波时差、补偿中子和补偿密度共5个参数进行聚类分析和判别分析,实现由取心井段到全井段储层流动单元的刻画,将XS1井区火山岩储层流动单元分为由好到差Ⅰ至Ⅳ类.各类储层流动单元与储集空间的配置关系为：Ⅰ类和Ⅱ类为孔隙-裂缝型,Ⅲ类为孔隙型或裂缝型,Ⅳ类为孔隙型.最后在单井识别刻画基础上,通过井—震联合解释剖面刻画储层流动单元空间展布形态和延伸规模.

英文摘要：

Based on the logging data, and identified the isolate barrier beds by lower limit of physical property in effective reservoirs,and two kinds of isolate barrier beds in wells XS1 area are identifyed, they are volcanic barrier which caused by physical property change and sedimentary barrier. Then studyed on the connected volcanic rocks bodies among the isolate barrier beds. Combined with the qualitative and quantitative analysis to identify the reservoir flow unit in the connected volcanic rocks bodies. Using the method of qualitative analysis to determined the obvious boundary in reservoir quality changing , which happened on the lithology-lithofacies boundary and some logging curves changing boundary. Further,using the method of quantitative analysis to identify reservoir flow units among the boundaries. The method of quantitative analysis is on the basis of core data and logging data, by use of parameters which are porosity （Ф）, permeability （ K）, interval transit time （ DT）, compensated neutron （ NPHI）, compensated density（RHOB） to cluster and discriminant analysis for identifying the flow unit from the core sections to all sections in wells XS1 area, and also, four types of volcanic reservoir flow units have been identifyed. Classification from good to bad is I, II, III, IV. The class I and II is the type of porosity-fracture, and the class III is the type of porosity or fracture, and the class IV is the type of porosity. Finally, in the identification of single well basis, Through well-seismic explaining profiles research the shape and scale of volcanic reservoir flow unit.
