摘　　要：介绍了新疆曲曼高温地热田的地热地质背景,利用水质测试结果分析了地热田及其邻区一带地热水、浅表冷水及冷-热过渡水的基本化学组分和地热水标性组分特征,并研究了热水化学组分来源及其运移规律。在此基础上分析了深部热储的水岩平衡状态,计算了热储温度。研究表明:地热水的化学成分以Na^+、Cl^-和SO_4^(2-)为主,Ca^(2+)和HCO_3^-次之,为典型的高温地热流体化学类型;地热流体在热田中部呈垂向上涌,在热田南部、东部及北部地热流体经深部垂向上涌后发生了明显的侧向径流;曲曼地热田深部热储为还原环境,渗透性较强,具中强的地热活动背景,计算热储温度在114~186℃之间,温度背景中等偏高。Geological and geothermal background of the Quman geothermal field is introduced in this paper.The basic characteristics of chemical components and special components of the hot water,the shallow cold water and the cold-hot mixed water are examined in the geothermal field and its adjacent areas. The resource and migration regularity of the chemical components of the geothermal water are studied. The water-rock equilibrium state in the deep geothermal field is interpreted,and the temperature of the geothermal reservoir is calculated. The research results show that the Na~＋,Cl^- and SO4^（2-） are the principal chemical constituents,and Ca^（2＋）and HCO3^- are secondary in the geothermal water which are typical in high temperature geothermal fluids. Thermal fluids in the central geothermal field upflow,and in the south,east and north the thermal fluids are obviously lateral runoff after upflow. The deep part of the geothermal field is a reduction environment,its permeability is strong,and the geothermal activity background is medium-strong. The temperature of the geothermal reservoir calculated ranges from 114 ℃ to 186 ℃,and the overall background temperature is high.
