DDCO型双源距碳氧比能谱测井应用效果评价

Application evaluation of DDCO type dual source-detect C/O spectral logging technique

碳氧比测井是目前套管井中解释水淹层的一种重要方法,通常是利用碳氧比测井资料评价地层剩余油饱和度和判断水淹层级别,其结果对新井射孔选层、堵水作业及补孔起到了较好的指导作用。文章介绍了DDCO型双源距碳氧比能谱测井技术的方法原理、用途及优越性等特点,并选取测井实例论述仪器的技术性能和应用效果。

C/O logging is an important method to explain watered-out zones in cased holes currently.Usually C/O logging data is used to evaluate residual oil saturation and judge watered-out zone class.Applications of C/O log result directs perforation-selecting in new well and perforation-adding in old well,as well as block off,etc.This paper introduces the characteristics of DDCO type dual source-detect C/O spectral logging technique,such as method,principle,use and superiority etc.With practical logging examples,the paper discusses instrumental technique function and its applied result.
