摘　　要：云南西部陇川县勐约乡研究区小范围内出露地热泉,该区地热成因及地热田范围并不明确,地热成因争议较大。本文以勐约地热田为研究对象,结合前人研究成果和区内地热钻井资料并在此基础上开展了对地热成因分析,在盖层、热源、热储和热通道等要素方面对该区地热条件、地温场特征、地热形成机理进行研究,构建地热地质成因模型。综合分析认为:(1)水化学类型为HCO_(3)^(-)~Na^(+)型水;(2)该区地热田热源主要来源于上地幔的岩浆,高热岩浆囊构成本区主要热源。In the research area of Mengyue Township,Longchuan County,western Yunnan Province,geothermal springs are found in a small area.The scope of geothermal genesis and geothermal field in this area is not clear,and the geothermal genesis is controversial.This paper takes Mengyue geothermal field as the research object,combines previous research results and geothermal drilling data in the area,and carries out geothermal genesis analysis on the basis of this.The geothermal conditions,characteristics of geothermal field and geothermal formation mechanism in this area were studied in terms of cover layer,heat source,heat storage and heat channel,and the geological genetic model of geothermal was constructed.The comprehensive analysis shows that:(1)the hydrochemical type is HCO_(3)^(-)~Na^(+) water;(2)the heat source of the geothermal field is mainly from the magma of the upper mantle,and the high hot magma sac is the main heat source in this area.
