Fluid flow in porous media can be generally categorized into four technical areas: single phase flow in homogeneous reservoir, multiphase flow in homogeneous reservoir, single phase flow in heterogeneous reservoir, and multiphase flow in heterogeneous reservoir. In the technical domain of transient pressure and rate analyses, although extensive research and engineering work have been conducted in these four areas, the majority of the outcomes were done for the first two technical areas. There were not many technical solutions for single and multiphase fluid flow in heterogeneous reservoir in a relative strict sense; this is mainly due to the complexity of fluid flow in formation with heterogeneity. Our recent research work has successfully built single-phase flow model for 2D/3D heterogeneous reservoir using rigorous semi-analytical methodology. The outstanding advantage of the new methodology is the highly accurate results generated for the entire reservoir domain with 2D/3D geometry. Using this methodology, different types of wells and reservoir heterogeneity features can be integrated into the model and the well pressure and production responses can be simulated and analyzed accordingly. The new research outcome has greatly enhanced petroleum engineers' technical position in terms of understanding, analyzing and managing the real reservoir performance.

多孔介质中的流体流动通常可以分为四个技术领域：均质储层中的单相流动、均质储层中的多相流动、非均质储层中的单相流动和非均质储层中的多相流动。在瞬态压力和流量分析的技术领域中，尽管在这四个领域中已经进行了广泛的研究和工程工作，但大多数成果都是针对前两个技术领域完成的。非均质油藏中单相和多相流体流动的技术解决方案相对严格意义上的不多，这主要是由于非均质地层中流体流动的复杂性。我们最近的研究工作已经成功地建立了单相流模型的二维/三维非均质油藏严格的半解析方法。新方法的突出优点是为整个储层域的2D/3D几何图形生成高度准确的结果。利用该方法，可以将不同类型的威尔斯井和储层非均质性特征集成到模型中，并可以相应地模拟和分析井的压力和生产响应。新的研究成果大大提高了石油工程师在理解、分析和管理真实的储层动态方面的技术地位。
