井温在注产剖面解释中的应用实例

Case Studies of Interpreting a Production Profile or Injection Profile with Temperature Curves

多参数组合测井是提高注入剖面和产出剖面测井资料解释成果可靠性的有效手段。井温测井资料在注入剖面解释中可用于辅助判断吸水层位及吸水级别 ,验证封隔器和死嘴是否密封 ;在产出剖面解释中 ,井温测井资料有助于判断主产层 ,分清大层段内小层或厚层内各部分产液情况 ,以及校验套管和水泥环的完整性。通过一些典型实例分析 ,说明了带井温曲线的组合测井综合分析在注、产剖面解释中的重要性。

Multi-parameter combination logging is a trend and valid means to enhance the reliability of interpretation results of an injection profile or a production profile. In case of injection profile interpretation, temperature logs are useful in identifying injection intervals, classifying water in-take grades, finding leakages through packer or dead-end water distributor, and locating flows from broken casing or behind casing. In case of production profile interpretation, temperature logs are useful in figuring out the main entrance points of flow, showing the entrance profile of laminated formations and verifying the integrity of an interval of casing or cement sheath. Through some case-studies, it is illustrated that the technique of combined logging with temperature curves is valuable to be spread.
