|
摘要
论文首先分析了研究区东营市东营区地热地质条件,在此基础上,进行了地热水取样和测试工作,查明了地热水化学特征、补给来源和年龄,最后利用储量模型法计算了东营区的地热资源储量。结果表明:馆陶组地热水中以Cl-及Na~+、Ca~(2+)离子占优势,水化学类型以Cl-Na型为主;东营组地热水中离子以Cl~-、Na~+和Ca~(2+)离子占优势,水化学类型以Cl-Na型和Cl-Na·Ca型为主;研究区地热水来源为大气降水与沉积水或封存水混合作用形成的;地热水年龄在54 a以上;研究区馆陶组地热流体储量为551.16×10~8 m~3,热储量2 112.02×10~(16) J;东营组地热流体储量为568.51×10~8 m~3,热储量为2 963.51×10~(16) J,研究区地热流体总储量为1 119.67×10~8 m~3,总热储量5 075.53×10~(16) J。
It is enrich geothermal resources in Dongying district, Dongying city, but it is not clear at present geothermal water characteristics and reserves which restrict the development and utilization of geothermal resources. In the paper, the geothermal geological conditions in the study area were analyzed firstly, and on the basis, the geothermal water was sampled and tested which find out the geothermal water chemical characteristics, the source of supply and the age. Finally, the reserves of geothermal resources was determined by reserves model method. The results showed that: the ions of Guantao Formation geothermal water were enriched in Cl~- and Na~+, Ca~(2+).The hydrochemistry type was Cl-Na. The ions Dongying formation geothermal water were enriched in Cl~-, Na~+ and Ca~(2+) ions. The hydrochemical types were Cl-Na and Cl-Na·Ca; The recharge of geothermal resources were atmospheric precipitation, deposition sources mixed water or seal water, and the age of geothermal water was larger than 54 a; The geothermal reserves of Guantao formation was 551.16×10~8 m~3, heat storage capacity was 2112.02×10~(16) J; the geothermal reserves of Dongying formation was 568.51×10~8 m~3, heat storage capacity was 2 963.51×10~(16) J. The total geothermal reserves in study area was 1 119.67×10~8 m~3, the total heat storage capacity was 5 075.53×10~(16) J.
