| Abstract |
It has made considerable progress in decade on the development and utilization of geothermal resources, including geothermal power generation of high temperature geothermal resources and direct uses of intermediate-low temperature geothermal resources, in China mainland. There are 1620 localities of geothermal uses equivalent to 5 million tons standard coals nationwide. The geothermal utilization entered the markets and has a certain competitiveness. By geological survey, there are about 255 high-temperature geothermal areas, which appear suitable for purpose of electricity generation, with potentials of 5800 MW for 30 years in Chinese mainland. The projects of high temperature geothermal electricity generation will concentrate in southern Tibet and western Yunnan. The major projects are the exploitation of deep reservoir in the Yangbajain field and operation of the future geothermal power station in the Rehai field in Tengchong County of Yunnan Province. The intermediate-low temperature geothermal resources are widespread and large potential countrywide. The major projects are co-utilization of low temperature brine in highlatitude region and take geothermal heating as dominant field. The further works in exploitation of geothermal resources include: 1) research on reservoir engineering and geothermal environment effect to raise the utilization ratio of thermal energy and to improve eclogical environment; 2) research on geopressured geothermal resources; 3) progressive establishment and amplification of technological standard and rules of operation for geothermal exploration and exploitation to probel the geothermal industrialization; 4) developing of geothermal tourist and balneological network. In past decades, the great advances in geothermal development and technology have been made by National Science and Technology Development Plan of eighth five year plan. These achievements can be concluded as follows. |
