【摘要】 利用碳氧比规范化处理,将碳氧比值限制在广义动态范围之内解决零值漂移问题,使用通用解释模型处理碳氧比资料。利用试验数据分析了碳氧比能谱测井零值漂移与产额的关系。建立了高精度碳氧比能谱精细解释标准。在精细研究和动态分析的基础上,结合多种测井资料,综合评价储层,取得了很好的地质效果。该方法实际处理了大庆、辽河等油田的多口井,效果表明,该解释方法的综合解释符合率在80%以上。更多还原

【Abstract】 In this paper, through working on C/O ratio to get rid of zero drift, and limit the C/O radio to the generalized performance range, and use universal interpretation model to deal with data of C/O ratio. Through combinating the experiment data, the relationship between the zero drift and the output in C/O ratio spectrum log is obtained. And the standard of high precision C/O ratio energy spectrum interpretation is received. Based on careful research and dynamic analysis, using many kinds of logging data and evaluating the reservoir, then better geological effect is obtained. This method is applied in many wells in Daqing and Liaohe oil field. The result indicated its precision ratio is more than eighty percent.更多还原
