| Abstract | The Yellow River is the second largest river in China. Its delta has an area of 9600 km2. There are three kinds of low temperature reservoir; the upper Tertiary Guantao Formation, the lower Tertiary Dongying Formation and the Cambrian-Ordovician Formation. The temperature gradients of the reservoirs were evaluated and found to be between 50?C and 100?C, with the heat source originating from the continental heat flux. Assuming no recharge, and a development life of 100 years, the allowable extraction of geothermal water is 15,918 m3/d and the usable heat energy is l10,984MW, being equal to 1 1 .56Mw/km2, showing good potential for development of the geothermal resource. |
