Abstract: This paper analyzed the geothermal resources characteristic of PetroChina, as well as the superiority of developing geothermal resources, summarized three basic types about the geothermal resources in oil regions, and proposed four modes for developing the geothermal resources, i.e. themode for developing conventional geothermal water resources, themode for developing oilfield production water type geothermal resources, the mode for developing shallow geothermal resources, and mode of utilizing mid-low temperature geothermal resource for power generation. According to domestic energy conditions and national policies as well as our own superiority, this paper looked forward PetroChina's prospect for developing geothermal resources. For PetroChina, geothermal resources were rich, and the development & utilization of geothermal resources should rely on oilfields and comprehensive utilization, taking advantage of abandoned wells and oilfield produced water, which could improve working and living environment in oil regions and reduce energy consumption. At the same time, the geothermal resources could be used to generate power in some areas of higher temperature geothermal resources. PetroChina consumed huge energy, owned large space to save energy, and had broad prospect for development and utilization of geothermal resources

Key words: PetroChina, geothermal resources, development and utilization, four modes
