摘　　要：示踪相关流量测井用来确定注入井的注入剖面,既能克服同位素测井技术的沾污、大孔道及高粘度聚合物等因素对测井资料的影响,也能克服中子氧活化测井测量下限高、成本大的局限。同时对低孔低渗油藏、纵向跨度长、注采关系复杂等情况具有较好的适应性,但在现场测试及资料解释精度和准确度方面依然存在不足。通过对示踪相关流量测井的数学模型和测试效果影响因素进行研究,从测井方法设计和解释方法两个方面进行分析,以实验室模拟的方式进行设计优化,用多种读值法对比确定合适的解释方法。通过优化示踪相关流量测井设计和解释方法,能够排除部分干扰因素的影响,提高测井及解释的精度和准确度,达到对示踪相关流量测井技术进一步优化的目的。Tracer relative flow logging is used to determine the injection profile of the injected well. It can not only overcome the influence of contamination,high capacity channels and high viscosity polymers in isotope logging technology,but also overcome the limitations of high measurement lower limit and high cost in pulse neutron oxygen activation logging technology. Meanwhile,it has a good adaptability to the low porosity and low permeability reservoirs,long longitudinal span and the complex relationship between injection and extraction. But there are still deficiencies in the accuracy of field testing and data interpretation. This research studied the mathematical models of tracer relative flow logging and the influencing factors of test effect,analyzed from two aspects of logging method design and interpretation method,optimized the design in the form of laboratory simulations,compared multiple read-value methods to determine the appropriate interpretation method. By optimizing the tracer relative flow logging design and interpretation method,we can eliminate the influence of some interference factors and improve the accuracy of logging interpretation to achieve the purpose of further optimization of tracer relative flow logging technology.
