【摘要】 页岩气是目前世界上新型战略能源。大量研究表明,我国现有页岩气很大一部分分布在南方碳酸盐岩地区,该地区复杂的地质地表条件使得地震野外施工困难,资料品质普遍不高,地震解释工作具有较大难度。提出了适于复杂地质地区页岩气勘探的电磁方法,对其中音频大地电磁测深和复电阻率法进行了探讨。更多还原

【Abstract】 The shale gas is a new kind of strategic energy in the world.Improving the speed of exploration and production of such a non-conventional resource has been a global choice of those countries or districts with rich shale gas resources.Previous researches have revealed that China has equivalent amount of shale gas with USA.Many research results in China show that the southern China is one of the potential areas for shale gas exploration.However the complex topography with carbonate covers and sophisticated geological structures in southern China are a main difficulty for seismic exploration to get good data.There are not any successful exploration cases for shale gas by EM method in China.This paper,we presents an idea of combined electromagnetic exploration method which consists of the audio magnetotellurics sounding and complex resistivity method suitable for shale gas exploration in such kind of rugged area.更多还原
