宁晋凸起北段地热资源潜力评价与长输开发模式

Evaluation of the potential for geothermal resource development and long-distance transmission technology in Northern section in Ningjin Uplift

  • 摘要: 宁晋凸起地热资源禀赋优越,但与主要用能市场晋州城区存在空间分隔,地热资源规模高效开发受到制约。基于地质与热储特征分析,优选宁晋凸起北段为有利区;针对蓟县系雾迷山组与长城系高于庄组两套主力热储层,采用热储法分层系计算资源量;通过数值模拟比选井网方案,并进行经济敏感性分析,提出了长距离远输开发方式。计算表明,宁晋凸起北段地热资源量为20.55×108 GJ,可采地热资源量3.08×108 GJ,基于此资源量,研究提出了建设约10 km长输管线的方案,理论上可满足约718×104 m2的供暖需求,其规模效益可有效平衡长输管网的投资与运维成本。晋州地热长输供暖项目的成功论证了中低温地热源进行长距离管输供暖的技术经济可行性,为解决类似资源与市场不匹配难题提供了可行路径。

     

    Abstract: The Ningjin Uplift exhibits sound endowment in geothermal resource. However, the distance from the primary energy market in Jinzhou city restricts the efficient development of geothermal resources on a large scale. On the basis of analysis of geology and geothermal reservoir natures, the northern part of the uplift is selected as the favorable area. The Wumishan Formation of the Jixian System and the Gaoyuzhuang Formation of the Changcheng System are two main geothermal reservoirs, for which the resource potential is calculated layer by layer using the volumetric heat-in-place method. Based on the well pattern schemes compared via numerical simulation and economic sensitivity analysis, a long-distance transmission development mode is proposed. The calculations present that the geothermal resources in the northern part of the Ningjin Uplift is totally 20.55×108 GJ, with a recoverable resource of 3.08×108 GJ. Thus, a scheme on construction of a long-distance pipeline around 10 km is proposed. Theoretically, this pipeline can provide heat for an area of 718×104 m2 or so, and the economies of scale can effectively balance the investment and operational costs of the long-distance pipeline network. The success of Jinzhou long-distance geothermal heating project proves the technical and economic feasibility of using medium and low-temperature geothermal energy as a direct heat source for long-distance pipeline transmission and has far-reaching significance in addressing the similar challenges of resource supply and market demand.
