井间示踪剂监测技术在油藏非均质性描述中的应用

APPLICATION OF WELL-TO-WELL TRACER TEST ON RESERVOIR HETEROGENEITY DESCRIPTION

从注水井注入示踪剂段塞，在周围生产井监测示踪剂的产出情况，可用示踪剂浓度随时间变化来表示，称为示踪剂产出曲线。通过对示踪剂产出曲线进行拟合分析，可以对油藏的非均质性进行描述，本文论述了井间示踪剂测试的基本理论、物理模型和计算方法，并进行了实例分析。结果表明，本文所述的物理模型和计算方法可用于示踪剂产出曲线的定量计算，其计算结果可用来分析油藏平面上和纵向上的非均质，为确定调剖剂的类型和用量提供依据。

The preduction curve of tracer from production well by using the concentration oftracer with time can be used to deseribe the raservoir heterogeneity from injection to production well. This paper introduces the basic theory. physical model. calculation method and processing of tracertest. Finnally this.paper gives the field example. The result shows that physical model and calculationmethed in this paper can be used to calculate the produce curve of tracer.the result of calculation canbe used to analyze the reeervoir hcterogeneity and determine the type and volume of the profile controlagents.
