A review of the pressure transient analysis of flow in reservoirs having natural fractures, vugs and/or caves is presented to provide an insight into how much knowledge has been acquired about this phenomenon and to highlight the gaps still open for further research. A comparison-based approach is adopted which involved the review of works by several authors and identifying the limiting assumptions, model restrictions and applicability. Pressure transient analysis provides information to aid the identification of important features of reservoirs. It also provides an explanation to complex reservoir pressure-dependent variations which have led to improved understanding and optimization of the reservoir dynamics. Pressure transient analysis techniques, however, have limitations as not all its models find application in naturally fractured and vuggy reservoirs as the flow dynamics differ considerably. Pollard’s model presented in 1953 provided the foundation for existing pressure transient analysis in these types of reservoirs, and since then, several authors have modified this basic model and come up with more accurate models to characterize the dynamic pressure behavior in reservoirs with natural fractures, vugs and/or caves, with most having inherent limitations. This paper summarizes what has been done, what knowledge is considered established and the gaps left to be researched on.

本文对具有天然裂缝，孔洞和/或洞穴的储层中流动的压力瞬态分析进行了综述，以提供有关该现象已获得多少知识的见识，并突出指出仍有待进一步研究的空白。采用了一种基于比较的方法，其中涉及多位作者对作品的审查，并确定了限制性假设，模型限制和适用性。压力瞬变分析提供了有助于识别储层重要特征的信息。它还提供了对复杂的依赖于储层压力的变化的解释，这些变化导致对储层动力学的更好的理解和优化。但是，压力瞬态分析技术 由于其流动动力学差异很大，因此并非所有模型都适用于自然裂缝和松散储层，因此存在局限性。1953年提出的Pollard模型为这些类型的油藏中现有的压力瞬态分析提供了基础，从那时起，几位作者修改了该基本模型，并提出了更精确的模型来表征具有天然裂缝，孔洞的油藏中的动压力行为。和/或洞穴，其中大多数都有固有的局限性。本文总结了已完成的工作，认为已建立的知识以及尚待研究的差距。几位作者修改了该基本模型，并提出了更精确的模型，以描述具有天然裂缝，孔洞和/或洞穴的储层中的动压行为，其中大多数具有固有局限性。本文总结了已完成的工作，认为已建立的知识以及尚待研究的差距。几位作者修改了该基本模型，并提出了更精确的模型，以描述具有天然裂缝，孔洞和/或洞穴的储层中的动压行为，其中大多数具有固有局限性。本文总结了已完成的工作，认为已建立的知识以及尚待研究的差距。
