摘　　要：随着地热开发的不断深入,持续高效开发地热资源,实现地热资源的采灌均衡,是亟待解决的问题。在Petrel(勘探开发一体化软件平台)这一石油行业地质建模软件基础上开发出适合地热地质建模的应用。应用多种地热地质资料在Petrel软件建立地学平台,开展地热地质要素研究,最大限度地集成多种资料信息,提高了地热地质要素的研究水平。将规模比较小的油气藏建模拓宽到建立大规模热储层模型,不但保证建模精度,在规模上也满足地热地质的需要。能够根据地热地质概念,利用多种信息,采用确定性建模和随机建模相结合方式,建立热储层温度场模型、压力场模型和有效热储层模型,形成了用Petrel软件建立热储层地质模型的方法。利用三维地质模型计算有效热储层资源量,受储层非均质的影响较小,更符合地下真实情况。准确的热储层三维地质模型及资源量评价,为辽河大民屯凹陷区热藏数值模拟及热藏开发方案的制定提供了扎实的地质基础,为科学开发利用该地区地热资源提供了数据支撑。As geothermal resource development continues to advance,addressing the challenge of sustainably and efficiently harnessing these resources becomes increasingly critical.This involves achieving a balance between the exploration and sustainable use(or"irrigation")of geothermal resources.To this end,the application of Petrel,a geological modeling software originally designed for the petroleum industry,has been adapted for geothermal geological modeling,offering a promising solution.The adaptation of Petrel for geothermal purposes involves establishing a geospatial platform within the software to manage and analyze a wide range of geothermal geological data.This platform enables comprehensive research into geothermal geological elements by integrating diverse data sets to the fullest extent,thereby enhancing the quality and scope of geothermal geological studies.This approach involves scaling up from traditional small-scale oil and gas reservoir modeling to large-scale thermal reservoir modeling.Such a transition not only maintains the accuracy of the models but also aligns with the scale requirements unique to geothermal geology.Utilizing Petrel,models of the thermal reservoir temperature field,pressure field,and effective thermal reservoir can be constructed.This is achieved by combining various types of data and employing both deterministic and stochastic modeling techniques,thereby establishing a robust method for thermal reservoir geological modeling using Petrel.A key advantage of employing a 3D geological model for calculating effective thermal reservoir resources is its reduced sensitivity to reservoir heterogeneity.This approach more accurately reflects real subterranean conditions,providing a more reliable basis for resource evaluation.The resulting accurate 3D geological models and resource assessments lay a solid foundation for the numerical simulation of thermal reservoirs and the development of comprehensive thermal reservoir management plans.This,in turn,supports the scientific and sustainable exploita
