井温曲线在注产剖面测井资料分析中的应用

Application of Temperature Curves to Logging Data Analysis for Injection and Production profiles

注入、产出剖面资料在生产测井中被广泛应用,由于个别井井况不同,常规多参数组合测井对油水井动态评价存在自身的局限性,对实际存在的一些问题并不能很好地解决。通过测井实例,说明测量静态井温,在应对低注入量、沾污严重、大孔道、查漏找窜、压裂堵水等疑难井、特殊井的问题分析处理上,具有一定指导意义。

lnjection and production profile datum are widely used during production well logging, and due to differential well conditions,eonventional well test using muhiple variahles has its limitations when it cumes to assess oil and water well, and Iherefore cannot he applied to certain special eases in the field. The paper demonstrates several ease studies based on aett,al fiehl test, explains approach to measure static well temperature, and shows that static well temperature curve data can be helpful to handling tough scenarios sueh as low injection rate, severe contamination, large pore channels, leak detection, fracture and water plugging, and so on.
