松辽盆地北部地热资源分布特征及开发对策
Distribution characteristics and development strategy of geothermal resources in northern Songliao Basin
摘要
Abstract
Songliao Basin is the largest onshore hot basin in China with maximum geothermal gradient and abundant geothermal resources.The problems of undetermined geothermal resources scale and favorable areas,late start of geothermal development and utilization,and immature related core key technologies and supporting engineerings cause difficulty to guide efficient development of geothermal resources.Occurrence characteristics of geothermal re-sources in northern Songliao Basin are emphatically analyzed based on study of geothermal gradient,rock thermal conductivity and heat flow.Development strategy for geothermal resources are discussed and supporting develop-ment and comprehensive utilization techniques are established based on its distribution characteristics.The results show that northern Songliao Basin has characteristics of high-temperature hot basin.Geothermal resources are main-ly divided into 2 types,namely hydrothermal and rock thermal.Sandstone geothermal water of middle-shallow hy-drothermal layers is well-developed in the north and poor-developed in the south.Water layer thickness in Lindian and Heiyupao zones of Binbei area is up to 200 m,with porosity generally exceeding 20%,being the most favorable areas for geothermal water development.Deep rock thermal geothermal resources have large thickness,high temper-ature and large resource scale,serving as the main substitute resource for oil production area.Development strategy is proposed including constructing geothermal development test zones by types,tackling the bottleneck of geother-mal development techniques,increasing policy support for geothermal heating projects and promoting research and development of geothermal techniques,so as to provide security for efficient development of terrain energy.The re-search provides theoretical basis for optimization and development planning of pilot test area in northern Songliao Basin.关键词
