【摘要】 地热水的开发利用为郑州市经济、社会的发展和居民生活水平的提高做出了巨大贡献,但由于缺乏科学、合理、统一的开发利用规划,造成了市区新近系地热水资源的过量开采,引起地热水水位持续下降。同时,行业之间用水量分配的不合理,抑制了地热水资源原有经济效益的发挥。因此,为使地热资源得到合理的开发利用,开展郑州市区地热水资源科学优化配置研究,对于实现郑州市区地热水资源可持续开发利用具有重要意义。本文根据郑州市区的地质条件,在系统分析了郑州市区热储特征的基础上,对郑州市区地热水资源开发利用现状进行评价,采用灰色模型系统预测法,预测了郑州市区未来年各行政区、各行业地热资源需水量,并应用模糊多目标线性规划方法,构建了郑州市深部地热水资源优化配置数学模型,制定了郑州市区地热水资源优化配置方案,为郑州市区地热水资源的合理开采及利用提供理论依据。本次研究所取得的主要成果有:(1)郑州市区沉积盆地热储温度随深度的增加而递增,地温梯度大于3℃/100m的区域呈条带状分布于市区西南、东、东北部部分区域。(2)郑州市区地热水水化学类型以HCO3—Na型为主,部分为HCO3—Na?Ca?Mg型,矿化度随埋深的增加而增大。(3)针对埋深小于800m的热储层和埋深大于800m的热储层,分别评价了其开采程度,并据此制定了地热水资源开发规划。(4)针对郑州市区地热水资源开采利用不合理的状况,应用模糊多目标模型进行了地热水资源利用的优化配置,得出至2010、2015年郑州市区地热水资源开采总量应控制在721.93万m3和886.52万m3,预计实现经济效益分别为3787.06万元、4535.6万元左右的结果。更多还原

【Abstract】 There was a great contribution of the development and utilization of geothermal water in the Zhengzhou City to the economic and social development and the improvement of living standards. Leading to the over-exploitation of the geothermal water resources, and the geothermal water level continued to drop and expanding cone of depression, due to lack of scientific, rational, unified development and utilization of geothermal water. At the same time, it inhibit the economic benefits of geothermal resources in original cost because unreasonable distribution of water between different trades. Therefore, there is a great significance of carrying out the research of science and optimal allocation of geothermal water resources in Zhengzhou City in order to make rational use of geothermal resources.Based on the geological conditions of the urban area in Zhengzhou, in the systematic analysis of the Zhengzhou urban area of geothermal reservoir characteristics, the development and utilization of geothermal water status in Zhengzhou was evaluated.The demand water of various sectors and administrative districts in the next few years had been predicted with Gray model. Fuzzy multi-objective linear programming method is applied to built deep geothermal mathematical model in Zhengzhou for optimal allocation of water resources. The utilization and optimal allocation program of geothermal water resources in Zhengzhou urban area has been developed.The geothermal wells in Zhengzhou urban had been planned layout, development and utilization of partition scheme was proposed, the theoretical basis of the rational exploitation and utilization of geothermal water is provided.The conclusions of the study include:(1) In Zhengzhou urban sedimentary basins ,heat storage temperature increases with depth increasing, Temperature gradient is greater than 3℃/100m area were banded structure in the southwest,urbaneast, north-east of urban.(2) In Zhengzhou urban, water chemical types are mainly HCO3-Na type, part of the HCO3-Na ? Ca ? Mg type, with the depth, the degree of mineralization increases.(3) Depth of less than 800m for the thermal reservoir and the depth is greater than 800m of the heat reservoir, the extent of their exploitation are evaluated, and accordingly developed a geothermal water resources development planning.(4) For the status of geothermal water resources are unreasonable exploitation in Zhengzhou urban, it’s carry out geothermal optimal allocation of water resources with the Fuzzy multi-objective model .the result is that the exploitation of geothermal water resources in Zhengzhou in total quantity should be controlled at 7.2193 million m3 by 2010, and 8.8652 million m3 by 2015, is expected to achieve the economic benefits of 37.8706 million yuan by 2010, about 45.356 million yuan by 2015.更多还原
