大地电磁测深法在石油地质调查中的应用

摘要

A magnetotelluric (MT) sounding was carried in the coqen-dongcuo zone of qinghai-tibet plateau. The article gives technique of data collection and processing and shows a good resistivity sections. Base on the preliminary interpretation, article deduced the boundary, stratum, basement depth and structure of fracture zone. The results provide useful geophysical information for the evaluation study of oil and gas in this zone.%介绍了大地电磁测深法(MT)在青藏高原措勤～洞错东剖面勘查中,其数据采集和数据处理的方法及工作要点,给出了清晰的剖面MT电阻率断面图像成果.通过成果的分析解释,查明了措勤盆地的边界、地层和基底埋深以及断裂构造,为开展该盆地含油气性整体评价提供了科学依据.
