【摘要】 阐述了下扬子地区应用大地电磁(MT)方法和西南地区电磁方法找礁试验的勘探思路以及 MT 概查在苏皖南部的应用效果,说明电磁方法在南方海相碳酸盐岩地区油气勘探中发挥了作用,同时针对灰岩山区地震方法的困难,提出了试用长排列高次覆盖、互换位置放炮、利用震电效应三种方法。建议将南方油气勘探中的物探技术方法作为战略问题来抓。更多还原

【Abstract】 The paper expounds the magnetotelluric method used in the Lower Yangzi area,the explorational thinking of finding reefs by magnetotelluric method in southwest and the applied effect of probable prospect in the south of Jiangshu and Anhui by magnetotelluric method.It exptained that the magnetotelluric method is very usefule to oil/gas exploration in the carbonate rock area of the southern China.Meanwhile,it put forwords three methods in the mountain areas of linestone:(1)the exponding reflection spread with higher cover;(2)exchange the position of explosion and recorder;(3)make use of the seisrnic- electric effect.更多还原
