摘要: 近年来地热资源市场需求与日俱增,贵州遵义—金沙地热富集区的资源勘探和开发迎来了大好发展机遇。以往贵州的地热成井率总体不高,改变这种状况是地热地质工作的一项重要任务,其中地热井地球物理测井是一项重要措施。测井资料的解译存在不确定性,需要把测井理论和实践经验结合起来,以提高解译结果的准确度。通过遵义北郊某地热测井的勘探实例,综合分析了自然伽马、电阻率、自然电位、声波等物理参数在不同岩石上的测井响应特征,采用典型标志层测井特征法、地层序列测井特征法、断层的测井解译特征法、含水层的测井解译特征法和井温突变的测井解译特征法等5种方法,通过4个步骤,对井中的实测曲线进行了综合地质解释,确定了典型标志层,划分了地层层序,解译了断裂构造和含水层等, 为研究区地热的钻孔定位、地热井的设计和成井工艺的选择提供了地质依据。Abstract: In recent years, the market demand for geothermal resources has increased intensely, and resource exploration and development in the Zunyi-Jinsha area of Guizhou has meet great development opportunities. It is an important task of geothermal geology work to change the relatively low success rate of geothermal wells in Guizhou, of which the geophysical logging is an important measure. Uncertainty exists in the interpretation of logging data, and it is necessary to combine logging theory and practical experience to improve the accuracy of interpretation results. Based on the geothermal logging exploration example in the northern suburb of Zunyi, the authors in this paper have comprehensively analyzed the logging response characteristics of physical parameters on rocks, such as natural gamma, resistivity, spontaneous potential, and acoustic waves. The comprehensive geological interpretation of actual measured curve in the wells were conducted by the logging character method in typical marker stata, sequence logging feature method, fault logging interpretation feature method, aquifer logging interpretation feature method and well temperature mutation logging interpretation feature method and 4 steps, to determine the typical marker layers and divide stratigraphic sequence. Besides, the fault structure and aquifer were interpreted. This research would provide a geological basis for the geothermal drilling positioning, geothermal well design and well completion technology selection in this area.
