摘要
针对轮南油田经过多年的注水开发,常规同位素测井工艺受粒径、测试工艺以及井壁污染的干扰已经不能满足注水动态监测需求的问题,通过多方调研后,有选择性地引进了能谱水流测井技术。通过25井次的测试分析表明,能谱水流测试工艺能够准确地判断吸水井段各小层的吸水状况,为封堵管外窜、调整注水、措施挖潜、深部调驱等措施的实施提供了指导依据。
On the basis of 20 years＇ injection development in Lunnan Oilfield,traditional water injection profile logging method can not satisfy the requirement of dynamic monitoring purpose for its limitation on particle,test technology and wellbore pollution. In order to solve these problems,the technology of spectra flow logging has been adopted after some investigations. According to the analysis of 25 well test reports,this technology can quantitatively determine the fluid intake status of each layer in generalized injection wells,providing effective guidance for plugging the channeling behind casing,injection adjustments,recovery scheme improvements,deep profile control and so on.
