摘要
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。
By using ITTA interwell tracer testing and interpretation software and optimization method, this paper analyzed the produced tracer profile and calculated the permeability and the thickness of high permeability layer in E 3 1 reservoir. The permeability of high permeability layer increased by 2～4 folds after waterflooding, chemical tracer thiocyanate was more suitable for E 3 1 reservoir than nitrate. Interwell tracer testing is a useful tool to recognize reservoir heterogeneity and petrophysical parameters after waterflooding. It has improtant guiding significance for improving the effect of water plugging and profile control.
