摘要
为了合理开发利用地热资源,本文以天津滨海新区桥沽-看财庄新近系明化镇组地热流体为例,应用Visual MODFLOW软件对明化镇组地热流体进行数值模拟。对模型的识别与检验表明,所建模型能够较好的反映明化镇组地热流体的地下水位动态特征。计算得出明化镇组100年水位接近150 m的地热流体可采资源量为10.7×106m3/a。通过预测按设计开采量进行开采后明化镇组地热流体地下水位的变化趋势,每天新增1000 m3开采量是可行的。
In order to rational development and utilization of geothermal resources in Tianjin Binhai New Area, we take Minghuazhen geothermal fluid in the Qiaogu-Kancaizhuang Neogene Minghuazhen Formation as an example, do numerical simulation with Visual MODFLOW software. The result Indicate that the calculation model can reflect the dynamic characteristics of groundwater level in the geothermal fluid. It is suggested that in 100 years, geothermal fluid geothermal fluid level close to 150 m recoverable reserves is about 10.7 x 106m3/a. Accoding to the prediction of changes in the design of mining Minghuazhen geothermal fluid of underground water level, to add 1000m3exploitation of dayis feasible.
