该文采用井间示踪剂测试解释ＩＴＴＡ软件，利用最优化方法对Ｅ３１油藏生产井产出的示踪剂浓度剖面进行分析，计算了注入水波及的高渗透层位的渗透率和厚度。分析认为水驱后油层的渗透率变化很大，Ｅ３１油藏高渗透条带的渗透率增加了２～４倍；示踪剂硫氰酸铵与硝酸铵相比，硫氰酸铵更适合于Ｅ３１油藏。井间示踪剂测试是认识油藏非均质性和水驱后油藏物性变化规律的一种有效的方法，对于提高油藏的堵水调剖效果，具有重要指导意义。
In this paper, ITTA software is used to interpret ITTA software and the optimization method is used to analyze the concentration profile of tracer produced in the E31 production well. The permeability and thickness of the high permeable bed are calculated. The analysis shows that the permeability of the oil layer changes greatly after water flooding, and permeability of high permeable strips in E31 reservoir increases by two to four times. Compared with ammonium nitrate, ammonium thiocyanate is more suitable for ammonium thiocyanate E31 reservoir. Tracer cross-well testing is an effective way to recognize the reservoir heterogeneity and reservoir property change after waterflooding, which is of great guiding significance for improving the water plugging and profile control of reservoir.
