摘　　要：地热能具有清洁、低碳、环保、稳定的特点,干热岩作为地热能的一种,是一类新兴的环境友好型资源,能够有效推进构建能源结构利用的多元化。通过对研究区太古界干热岩地热储层综合评价技术的研究,参照岩性特征及储层发育特征,建立了利用多种测井信息进行岩性识别、储层划分和地层温度评价的方法;在岩心和岩屑录井资料分析的基础上,利用不同岩性测井曲线特征差异性分析和交会图进行岩性的识别和划分;结合常规测井、成像测井和偶极阵列声波测井等多种测井信息,形成干热岩地热储层的识别方法,并建立储层类别划分标准;利用时间推移测量井温的方式进行地层温度的推算。实际应用已证明这一测井评价方法的适用性与有效性,可为干热岩的有效开发提供技术支撑。Geothermal energy has the characteristics of clean,low-carbon,environmental and stable.As a new environment-friendly resource,hot dry rock geothermal energy is expected to promote the diversification of energy structure.The comprehensive logging evaluation techniques for the target block of Archean hot dry rock geothermal reservoir were conducted.And a method was established by using multiple logging information wells for lithology identification,reservoir division,and formation temperature evaluation,based on the lithological characteristics and reservoir development characteristics.On the basis of core and cuttings logging data analysis,the identification and division of lithology were carried out by using the analysis of differences in logging curve characteristics of different lithology and intuitive intersection plots.Besides,a recognition method for hot dry rock geothermal reservoir was formed,and reservoir classification standards were established,combined with various logging information such as conventional logging,imaging logging,and dipole array acoustic logging.The calculation of formation temperature was calculated by time lapse measurement of well tempetature.The applicability and effectiveness of this logging evaluation method has been proven in practical applications,providing technical support for effective development of hot dry rocks.
