Abstract: In order to analyze the thermal storage conditions of the geothermal area of Xiuwen Yangming Cultural Park in Guizhou,the geothermal structure of this cultural park is located in the northsouth fold troughtype deformation zone of Fenggang in the Upper Yangtze block.The relatively uplifted area in the southeast,the Gubao fault and the Maoshan fault meet at the acute angle area;the XinglongchangTiechang double anticline secondary fold power plant anticline is the main thermal storage structure in the area,and the Maoshan fault is the heat source channel in the area.The thermal storage units in the geothermal area of this cultural park are the Cambrian Loushanguan Group (∈2-3ls),Shi Lengshui Formation (∈2s),Gaotai Formation (∈2g),and Qingxudong Formation (∈1q) limestone,Dolomite limestone and dolomite;the caprocks are Permian Longtan Formation (P3l) clay rock and siltstone.The water output of geothermal well is 888 m3/d,and the wellhead temperature is 46 ℃,which is a geothermal resource with low temperature and hot water.Hot mineral water type is HCO3-Ca+Mg type,containing high fluorine,strontium,lithium,metasilicic acid,and weak alkaline water.It is concluded that the type of geothermal exploration is a combination of banded and layered thermal storage (type II3).
