摘　　要：随着油藏精细化管理水平的不断提高,为满足不同油藏、不同开发层系对能量的需求,解决层间矛盾日益突出的问题,采用偏心分注水工艺补充地层能量。偏心分注井的测试环境使得电磁流量﹑同位素测井技术、涡轮流量计测井技术等无法对各层位吸水情况进行细分。脉冲中子氧活化测井技术能很好地解决这些问题,但是氧活化仪器在应用过程中也遇到一些问题,针对这些问题,给出了原因分析和应对措施。With the continuous improvement of the refined management level of the reservoir, and in order to meet the energy demand of different development strata in the different oil reservoirs and to solve the problem of increasingly prominent contradictions among the layers,the eccentric partial water injection technology is used to supplement the formation energy. The electromagnetic flow logging technology, isotope logging technology and turbine flowmeter logging technology are impossible to subdivide the water absorption of each layer duo to test environment of the eccentric injection well. The pulsed neutron oxygen activation logging technology can solve these problems. However, the oxygen activation instrument also encounters some problems in the application processing in the eccentric separate injection well. These problems are analyzed, and the corresponding countermeasures are put forward.
