漳州地热田基岩裂隙水系统温度分布特征 总被引：1，自引：0，他引：1
为研究漳州地热田基岩裂隙水系统温度分布特征,建立了新的三维基岩裂隙水系统概念模型,并利用Fluent软件求解模型。结果表明:基岩裂隙热水温度场受到断裂区的强烈控制,在北东—南西向断裂中,强烈对流形成的高温热柱刺穿了基岩顶部形成热田高温中心;基岩热流在断裂区中部高温区达到最大,在北东—南西方向上最大值为343.02mW/m2,在北西—南东方向最大值为368.72mW/m2,并向边缘逐渐降低;第四系孔隙水的存在和运动使得地表热流的最大值和局部值降低。未来漳州热田应加强深部温度的测量研究。 相似文献

Research on the fault controlling mechanism of geothermal water in Zhangzhou Basin 总被引：1，自引：0，他引：1

下载免费PDF全文 Fault has an important influence on the storage and movement of geothermal water. The Zhangzhou Basin is wholly located in a granodiorite rock mass. Due to the low permeability of granodiorite, faulted structure has an evident control action on the hydrothermal activity of geothermal fields. Hot springs in Zhangzhou Basin crack along Pingtan-Dongshan Fault to the northeastern direction and emerge along Fu’an-Nanjing Fault. Through measurement of the temperature of several hot springs in the Basin, we found the temperature along the northwestern direction of Zhangzhou-Tianbao Fault is high and the temperature gap between the two sides of Yangxi-Yuanshan Fault is huge; the estimation of geothermal reservoir temperature of geothermal water through quartz geothermometer indicates that the geothermal reservoir temperature of the northern area of Nanjing-Xiamen Fault is obviously higher than that of southern area. Such result indicates that Fault obviously obstructs underground heat source. Under the condition that the average geothermal gradient of the Zhangzhou Basin is set, the circulation depth of the geothermal water of the Zhangzhou Basin measured by geothermal reservoir temperature is 3 550-5 200 m and the circulation depth of the geothermal water of the north of Nanjing-Xiamen Fault is deeper than that of the South. 相似文献

漳州地下热水开采与地面沉降预测 总被引：1，自引：0，他引：1
据福建省漳州市漳州地热详查报告(1988年),漳州市城区地热田孔隙热水水位降深1.16 m~5.0 m(平均4.41 m),允许开采热水资源5 410.08 m3/d,但目前的开采量为883.20 m3/d,仅占16%,若全部开采,势必引起地面沉降。根据漳州地热田水位降深段内土体浮力消失,相应自重应力增加而引起压缩变形原理,预测漳州地热田平均水位降深4.41 m引起的地面沉降值,Ⅰ级阶地为3.85 cm~8.66 cm,按有关地热田沉降资料研究,沉降差超过2.0cm时,地下水泥管道将会破裂。因此,漳州孔隙热水资源全部开采可能引起地面沉降,导致局部建筑物开裂,影响安全使用。 相似文献

勘探区位于漳州市以东约40km处,属低丘陵剥蚀区及海积阶地,因区内开发程度高,地面普遍硬化。依据区内的地质、水文及构造资料,决定采用抗电磁干扰强的CSAMT法与施工较为便利的微动测深法勘测地下热源。通过分析隐伏储热构造在CSAMT法与微动测深法剖面图上的响应特征,确定波速相对较低且存在低阻异常区域为储热控水构造有利区。综合考虑野外施工条件,在CSAMT法1线与微动测深线交汇处钻孔验证,结果显示,孔底温度为30.9℃,出水量为1243.21m3/d,表明CSAMT法联合微动测深法可有效探测该地热资源。 相似文献

大地电磁测深法在福建漳州地热区的应用 总被引：1，自引：0，他引：1
为了研究漳州地区深部构造和热源条件,在天宝、漳州、龙海一线进行了大地电磁测深测量工作。通过对大地电磁测深结果的分析和解释,表明在漳州地区龙海—浮宫一带上地幔高导基底明显上隆,在壳内10—13km深处具有明显的高导层,地表覆盖层电阻率很低。根据这些情况并结合地质资料推断,这一带地下存在着温度较高的热源及地下水补给条件,在地下水深循环和热对流良好的断裂交汇区,有可能形成水温较高的地热田。 相似文献

Characteristics of geothermal reservoirs and utilization of geothermal resources in the southeastern coastal areas of China 下载免费PDF全文
下载免费PDF全文 Based on regional geological setting, stratigraphic distribution and other geological conditions, this paper summarized three types of geothermal reservoirs in the southeast coastal areas of China: Cenozoic sandstone or sandy conglomerate reservoir, Mesozoic granite fissure reservoir and Paleozoic karst reservoir. Cenozoic sandstone or sandy conglomerate reservoirs are mainly located in Cenozoic basins, such as Zhangzhou, Fuzhou, Sanshui and Leiqiong basins. The Tertiary sedimentary basins such as Leiqiong Basin and Sanshui Basin, are controlled by NE-trending faults, while the Quaternary sedimentary such as Zhangzhou and Fuzhou basins are controlled by NW-trending faults. Mesozoic granite fissure reservoirs are mainly distributed in the southeast coastal areas, such as Zhangzhou, Fuzhou, Fengshun, Yangjiang and southern part of Hainan Province. The distribution of good Mesozoic granite fissure reservoir in these areas is mainly controlled by NE-trending faults. Paleozoic carbonate reservoirs are widely distributed in these areas. Most carbonate rocks are from the upper Paleozoic strata, such as those in the area of Huizhou in Guangdong Province. The major types of geothermal systems in the southeast coastal areas of China belong to medium and low-temperature convection. The geothermal resources developed from the ground to-3 000 m underground could be utilized directly for space heating, greenhouse heating, aquaculture pond heating and industrial uses, as well as other purposes. The geothermal resources with a depth of 3 000～6 000 m underground is mainly featured by Hot Dry Rock(HDR) with a temperature ranges from 150 ℃ to 200 ℃, which is conductive to the development of Enhanced Geothermal System(EGS) and can be utilized for power generation. 相似文献
