Tangshan region, Jiangsu Province, the amount of underground thermal water resources assessment
Bit m3 / a; C for the hot water heat,uggs online, in units of kcal / kg · ℃,ugg italia, take 1.10kcal/kg · ℃; t for the hot water temperature in ℃, take more than six 1601TI depth of geothermal wells average temperature is 58 ℃; t0 is the reference temperature (ie the local annual average temperature or underground heated surface temperature), take 20 ℃ (Table 1). Table 1 can be exploited to water resources and exploitable geothermal resources in the amount of table Table1Tableofthepermissiveminingyieldandthepermissiveminingenergyofgeothermalwater number of geothermal resources can be mined / × 10kcal · a1 predict the maximum depth of water the amount of exploitable geothermal resources standard coal equivalent ● / m109.573.0050.0036 .5018.25450.46300.31205.69150.1575.0829 ~ 3518 ~ 2412 ~ 187 ~ 133 ~ 96435.144290.142938.432145.001072.570 increase as the Earth of 2002 as ∞ Chih-4 Discussion and conclusion Tangshan dome anticline tectonic controls the formation of underground hot water Tangshan region. Anticline between the layers to form a good combination of reservoir, fractured carbonate rock karst system constitutes a hot water storage space and migration pathway of fracture, especially in the last EW fracture to the ring, the control of the geothermal field boundaries. Xu Deep possible fracture of a gold substrate was heat reservoir. Magmatic activity is to provide a heat source of geothermal fields. Tangshan underground water level is mainly affected by water extraction and precipitation, weather type is a dynamic labor exploitation. Development and utilization of the geothermal area is centered in the East Tangshan dome anticline plunge end of the base water level dynamics and the relationship between weather, ground water discharge and water level way of the formation mechanism, it can be almost geothermal system into the second input, single output lumped parameter system model. According to the model predicted that exploitation of underground water resources can be as follows: ① When the maximum water depth is 29 ~ 35m, the amount of exploitable resources, 109.5 × 10m3 / a, equivalent to 405.46 × 10kcal / a heat; ② when maximum level is 18 ~ 24m depth, the recoverable resource of 73.00 × 10m3 / a, equivalent to 300.31 × 10kcal / a heat; ③ When the maximum water depth is 12 ~ 18m, the amount of recoverable resources 50 × 10m3 / a, equivalent to 205.69 × 10kcal / a heat; ④ When the maximum water depth is 7 ~ 13m, the amount of exploitable resources, 36.5 × 10m / a, equivalent to 150.15 × 10kcal / a heat ; ⑤ When the maximum water depth is 3 ~ 9m when the heat can be open about 7000keal o1t standard coal mining resource of 18.25 × 10m / a,uggs kopen, equivalent to 75.08 × 10kcal / a heat. And that: the amount of underground thermal water resources for the 50 × 10m / a near (or less) as a reliable resource that can be mined, and 50 × 10 ~ 109.5 × 10m3 / a recoverable resources,jordan shoes, compared with vision. Lumped parameter model of the groundwater system is described by a stationary process, while the actual development of underground water may be a non-stationary process, which can be exploited in the ground water resource evaluation process has some limitations, long-term exploitation of resources can be the amount required in the future exploration and development phase to be corrected.
