摘　　要：介绍了利用集总参数模型对于地热田储层裂隙探讨的可能性。地下热储深藏于地下并且难以直接对其进行观测。对地热系统中不同储层之间连通性的研究尤其重要意义。目前,探测不同地热井之间由于储层裂隙而影响它们之间连通强弱常用的方法为同位素示踪法。但由于该方法仅能在定性方面评价地热储层之间的连通性。因此,探讨了另一种可能性,即通过利用集总参数模型模拟地热田响应的基础上,为地热田地质储层连通性能的定量分析提供借鉴意义。In this paper,the possibility of using lumped parameter model to study the fracture of geothermal reservoir is discussed. The underground thermal reservoirs are buried deeply and they are difficult to be observed directly. The study of connectivity between different reservoirs in geothermal systems is of significant importance.Currently,isotope tracer is the primary method of detecting the connectivity between different geothermal wells due to reservoir fractures. However,this method can only evaluate the connectivity between geothermal reservoirs qualitatively. Thus,in this paper,the possibility of using the lumped parameter model to simulate the geothermal field response is discussed,as is a reference for quantitative analysis of geothermal reservoir geothermal reservoir connections.
