【摘要】 近年来在西部油气新区勘探工作中,MT勘探成为油气前期勘探主要的技术手段之一。除发挥在短期内进行探边摸底、选坳定隆的作用外,配合地震资料进行主要目的层综合研究、综合分析也成为MT资料进一步发挥作用的一方面。本文结合西部WW盆地MT勘探资料,主要就MT资料所揭示的超低电阻率异常分布特征进行了模型模拟分析,对石炭系目的层低电阻率成因进行了推测,为油公司确定新的勘探靶区提供依据。更多还原

【Abstract】 MT method has been becoming one of the main techniques for early hydrocarbon exploration in West China in recent years.MT has been used not only for regional structural study,but also for comprehensive research and analysis combining with seismic data.In this paper,we set up models to simulate super-low resistivity shown in MT data of WW basin in west China to define origin of target layer-carboniferous which is of low resistivity,then provide evidences for determining new exploration targets for the oil company.更多还原
