摘要
鄂西地区地热较为丰富,然而保康县万年山地区地热勘探工作匮乏。为了查明保康县万年山地区中深部地热资源潜力,通过地面调查、物探、钻探等手段对该地区的地层、构造、水文地质、地球物理、地热热储和地热流体化学特征等进行综合调查研究,总结分析地热发育规律及成因类型,建立地热模型。结果表明,万年山地区地热热储主要发育层位为震旦系—寒武系的碳酸盐岩地层;地热流体具有高SO_(2)^(-4)、F-和Ca^(2+)的特征;深部热量向上部地层中传导的通道是保康—漆家山断裂;万年山地热属于断裂深循环型,地热井出水温度为58.6℃,水量为1229 m^(3)/d,规模达到中型。此研究可对今后鄂西地区同类型地热田的勘查和开发有一定的借鉴和指导意义。
The geothermal resources in the western region of Hubei are relatively abundant,but there is a lack of geothermal exploration work in the Wannianshan area of Baokang County.In order to identify the potential of middle and deep geothermal resources in the Wannianshan area of Baokang County,a comprehensive investigation and study are conducted on the stratigraphy,texture,hydrogeology,geophysics,thermal storage,and geothermal fluid chemistry characteristics of the Wannianshan area in Baokang County,Hubei Province,through ground investigation,geophysical exploration,and drilling.The geothermal development rules and genetic types of the Wannian Mountain area in Baokang are summarized and analyzed,and a geothermal model is established.The results show the main development layers of the Wannianshan thermal reservoir are the carbonate rock strata from the Sinian to Cambrian systems.Geothermal water bodies have the characteristics of high SO 2-4,F-,and Ca 2+.The channel through which deep heat is transmitted to the upper strata is the Baokang-Qijiashan Fault.The Wannianshan heat belongs to the deep fracture cyclic type,with geothermal well water temperature of 58.6℃and a water volume of 1229 m 3/d,reaching a medium-sized scale.This work has found a geothermal field with high mining value for the western Hubei region,which has certain reference and guiding significance for the exploration and development of similar geothermal fields in the western Hubei region in the future.
