泰莱断陷盆地西部地热资源的成因

泰莱中—新生代断陷盆地及其周边地区为地热资源的形成准备了良好的储热岩层和保温盖层。通过遥感图像处理和重力、航磁数据处理以及构造岩显微构造分析、断裂新活动调查,确定了断裂的力学性质和深层构造性质以及断裂的继承性、新生性,了解了地下水深循环增温的条件,针对地热形成必须具备的“储”、“盖”、“通”、“源”四大要素进行的分析,说明泰莱断陷盆地蕴藏着丰富的地热资源,为进一步勘探开发提供了依据。 

GENETIC FEATURES OF WESTERN GEOTHERMAL RESOURCES IN TAI-LAI DOWNFAULTED BASIN

Tai-Lai Mesozoic-Cenozoic downfaulted basin and its around region,in the movement and evolvement of the earth's crust for long time,the form of the geothermal resources are not only ready for good stored geothermal terrane and the cover of heat preservation,but also produce NW,NEE,SN,NNE-the four-group faults caused by difference movement.Fault mechanics properties,deep structure properties,fault inheritance and palingenetice properties,are determined by remote sensing imagines processing,gravity,aero-magntic data processing,analyzing microstructure of tectonic rock,and exploring new active faults,for this makes it possible to increase temperature of cycling underground water.The paper states the four elements of storage,cover,roution,and origin for forming geothermal by the large amount of actual data,it proves that Tai-lai downfaulted basin contains rich geothermal resources,and so it further provides evidences for us to explore and develop geothermal resources of Taian.
