摘要
为加快柴达木盆地深层卤水矿勘查评价和开发利用的研究进度,提供海西W地区地层物性参数和大致了解确定该区石盐层的埋深、厚度及结构。对青海海西W地区以钾为主的固液相盐类矿产开展了地球物理测井工作,本次测井工作选择多参数组合测井方法探测,通过对各钻孔测井资料的综合分析,并结合地质钻探资料加以对测井识别的岩性分层对比验证,获得了该区测井识别石盐层的测井响应特征。结果表明,W区石盐层均表现为低自然伽玛和高视电阻率的测井反映。这为更加快速有效识别本区石盐层段的划分和后期地质勘探开发提供了有力依据。
in order to quicken the research progress of exploration,evaluation,exploitation and utilization of deep brine deposits in Qaidam Basin,the physical parameters of strata in Haixi W area are provided,and the burial depth,thickness and structure of rock and salt beds in this area are roughly understood and determined.Geophysical logging work has been carried out for the solid liquid phase salt minerals in Haixi W area of Qinghai Province.This logging work selects the multi-parameter combination logging method to detect,through the comprehensive analysis of the logging data of each borehole.Combined with the geological drilling data,the lithologic stratification identified by logging is verified,and the logging response characteristics of identifying halite formations in this area are obtained.The results show that the low gamma ray and high apparent resistivity are well logging reflections in the rock salt beds in the W area.This provides a powerful basis for more rapid and effective identification of the division of rock and salt layers and later geological exploration and development in this area.
