用图版法分析示踪剂产出曲线

TYPE-CURVE MATCHING METHOD TO ANALYZE MULTI-WELL TRACER TEST

  • 摘要: 传统示踪剂产出曲线的分析方法是进行曲线拟合,该方法工作量大,且结果不唯一,因而提出用图版法来分析。该方法将常规时间域中的问题转换到频率域中,做出理论图版和实际图版。通过对比理论和实际的传递函数和相位谱,可快速估计出油藏的非均质性指标和孔隙体积,如果同时应用分配性和非分配性示踪剂进行测试,还可求出剩余油饱和度。用该技术进行了实例分析,与常规分析法所得结果非常一致。

     

    Abstract: The traditional approach to analyze multi-well tracer tests generally involves a history matching procedure that is time consuming and frequently results in a non-unique solution.This paper presents a typecurve matching method.First,we use theoretical frequency response functions to build the curve of transfer function and phase spectrum which is called theoretical curve.Second,we use Fourier analysis to transform the field tracer data from time domain to frequency domain,then plot the field curve of transfer function and phase spectrum which is called practical curve.The transfer function contains information regarding the characteristics of heterogeneous reservoir and the phase spectrum provides information about the presence of immobile oil phase.In a manner analogous to type-curve matching for well testing,we can analyze field tracer data by comparing the theoretical and practical transfer function and phase spectrum,both the heterogeneity index and pore volume can be easily and quickly estimated by this method.If the partitioning tracer and non-partitioning tracer were used simultaneously,then the residual oil saturation can be estimated.We demonstrate this method by analyzing field tracer data from the Xinjiang oil field,the results show very good agreement with other traditional methods.
