冲乎尔盆地地热资源储热特征及开发利用建议

Heat storage characteristics and utilization suggestions of geothermal resources in Chonghuer basin

冲乎尔盆地赋有丰富的地热资源,但开发利用却很缓慢。本文结合冲乎尔盆地相关情况,推测出冲乎尔盆地地热资源的成因和储量,对地热资源的开发条件进行分析,为实际利用提供参考。调查结果表明:调查区断裂构造发育,为地热流体的循环、运移和深部地热形成热对流提供了条件;区内的断裂裂隙、破碎带和松散岩石的发育,为地热资源提供了良好热水储存空间;大规模侵入岩浆岩和变质岩的发现表明深部发生过较为剧烈的岩浆活动,为地热提供了热源。经分析,研究区的水中含有大量矿物质,可开发利用的方向是饮用矿泉水、生活饮用水、渔业、农业等。该地热田区位条件较好,若可充分利用地热资源,则可以满足冲乎尔盆地周边稳定的地热资源需求。

Chonghuer Basin is rich in geothermal resources,but its development and utilization process has been rather slow.Based on the relevant situation of Chonghuer Basin,this paper deduces the cause and reserves of geothermal resources in Chonghuer Basin and analyzes the conditions for development of geothermal resources,providing reference for actual utilization.Investigation results show that the developed fracture structure in the survey area provides conditions for circulation,migration and deep geothermal convection of geothermal fluid;the developed fractures,fracture zones and loose rocks in the area provide good hot water storage space for geothermal resources;the discovery of large-scale intrusion of igneous rocks and metamorphic rocks indicates that relatively intense magma activity occurred in the deep area,providing heat source for geothermal energy.According to the analysis,the water in the study area was found to contain a large amount of minerals,and the potential directions for development and utilization could include bottled mineral water,domestic tap water,fisheries,agriculture,and other industries by making use of these mineral-rich waters.The geothermal field has good location conditions.If the geothermal resources can be fully utilized,it can reliably meet the sustained geothermal energy demand of Chonghuer Basin and surrounding areas.
