| 中文摘要: |
| 将音频大地电磁测深法（AMT）应用于五大连池地区的碳酸矿泉水勘查，以Occam（奥克姆）方法进行数据反演，揭示了研究区域深部电性特征，结果与地质资料的解释一致。研究区内实测三个AMT剖面的反演结果均显示，该区域深部存在多条明显的断裂带，其深度超过-2.5 km，走向北西，规模不一。这些深部断裂可能是CO2气体向上运移的通道，由此可以推断CO2储气层，并为最终圈定碳酸矿泉水范围提供依据。 |
| 英文摘要: |
| This work applied the audio-frequency magnetotelluric (AMT) method to exploration of carbonated mineral-spring water in the Wudalianchi region. Using the Occam method, the measured data was inverted to reveal the electrical structure beneath the study area, yielding results consistent with interpretation of geologic data. The three AMT profiles show the existence of several faults at depths more than 2.5 km, which trend all in northwest direction, with different scales. These faults are probably the main passages of CO2 migrating upward, which provides the evidence for inference of CO2 reservoirs and determining the boundary of carbonated spring-mineral water area. |
