关中盆地地热资源研究
|
摘要
关中盆地地热资源是中国西部最有代表性和地区特色的地热资源之一。选取关中盆地区域渭河北岸断裂附近的地热资源进行分析及研究,结果表明:关中盆地地热资源丰度高,具有产量高、压力高、自流水温度高、稳定性高、矿化度高、达标元素多等"五高一多"的特点和优势,地热资源分布呈现垂直多层楼式多热储层迭置特征,热储层分布广泛、面积大,深层3500m以下可能存在温度大于200℃的高温地热异常体资源,地热资源热源稳定充足,具有较高的热流值背景,可利用率高。此外,关中盆地地热资源含有丰富的水溶气,数据显示伴生气中氦气含量为0.101%~3.511%(平均1.295%),具有很大的氦气资源潜力。建议应进一步加大地热资源在供热采暖、地热水医疗保健、温水温室生态农业示范、矿泉水饮用等领域的开发利用;加大温度≥200℃的干热岩高温地热资源的开发利用,重点探索地热资源发电技术及工艺;加大地热资源水溶氦气提取回收技术的研发,建立氦气生产和战略储备基地。
Geothermal resources in Guanzhong Basin are the most representative and have regional character-istics in western China.The geothermal resources near north bank fracture of Weihe River in the Guanzhong Basin were analyzed and researched.The results show that the geothermal resources in the Guanzhong Basin have the characteristics and advantages of high abundance,high yield,high pressure,high artesian temperature,high stability,high salinity and multiple standard elements.They distribute as the characteristics of vertical multi-layer and wide and large multi-thermal reservoir overlay.The resources of geothermal abnormal area above 200℃ may exist in the deep formation below 3500 m.It has enough and stable thermal source at the background of high heat flow value.It can be developed and utilized with high efficiency.In addition,the geothermal resources in the Guanzhong Basin are rich of water-soluble gas.Helium(He) content in the asso-ciated gas is 0.101% to 3.511% with the average of 1.295% according to the data analysis,which shows great potential.It suggests that the thermal resources should be developed and utilized further in the fields of heating,medical care,warm water and greenhouse ecological agricultural demonstration and mineral water drinking.The high temperature geothermal resources with hot dry rocks at an d above 200 ℃ should be developed and utilized further.It should be focus on probing power generation technology by the thermal resources and developing extract and recovery technology of water-soluble helium of the geothermal resources.Production and strategic reserves base of the helium should be built.
