摘　　要：WITSML作为新一代井场信息传输标准,采用XML技术定义数据格式,在数据结构灵活性、跨平台兼容性方面具有较强的优势。WITSML文档的数据格式同XML文档一样由相应的数据模式定义和验证,以此来保障数据传输与交换过程的顺利完成。通过对XML数据模式相关概念的介绍,分析了WITSML数据模式的组成部分和数据类型,并以面向录井信息应用的"mudLog"数据对象为例,介绍"mudLog"数据对象各个数据组件的树型层次关系,解析WITSML数据模式文档的元素、类型、嵌套包含关系及应用方式,就录井信息的WITSML标准化工作进行了初步的探讨。通过对WITSML数据模式的分析,制定企业对外数据接口和信息交换标准,简化数据交换中间环节,进而实现大范围的信息共享。As a new generation of wellsite information transfer standard,WITSML uses XML technology to define data formats,which has strong advantages on data structure flexibility,cross platform compatibility.Like XML document,the data formats of WITSML document are defined and validated by the corresponding data mode to guarantee the successful completion of data transferring and exchange processes.By introducing the concepts of XML data mode,the authors analyzed the components and data types of WITSML data mode,and took 'mudLog' data objects that were used in mud logging information as an example,described the tree hierarchical relationships among data components of 'mudLog' data objects,analyzed the elements,type,nested relation of inclusion and application way of WITSML data mode document and discussed the initial WITSML standardized work with mud logging information.By analyzing WITSML data mode,the enterprise external data interface and information exchange standard were formulated,the intermediate link of data exchanging was simplified,and a broad range of information was realized to share.
