Liaohe rift abounds in geothermal resource. Vast quantity of geothermal data was accumulated over the past forty-year’s exploration. The geothermal field in our study area is jointly controlled by faults, lithology, caprock buried depth and hydrology, has a relatively high geothermal gradient which ascends southwards. The geothermal reservoir is continuously hosted in several sequences, represented by two major types, clastic sedimentary pore type and karst fissure type. The former one is chiefly hosted in the Cenozoic and Mesozoic, and the latter one in the Archean and middle-upper Proterozoic. This paper, based on a comprehensive assessment, indicates some favorable areas for geothermal resource, including Dawa-Haiwaihe area (the Cenozoic) and Shuguang-Dujiatai area (the Paleozoic and middle-upper Proterozoic). With the decreasing oil-gas reserves in Liaohe Oilfield, it is of economic and social significance to explore the geothermal resource in these areas.
