摘要
我国南方海相碳酸盐岩地层沉积区，是具有巨大潜力的油气远景区。但由于恶劣的自然条件，导致常规油气勘查方法在该地区基本失效。三年来，对该类地区应用以MT为主体的电磁方法进行试验，结果表明：虽然工区地表自然条件十分复杂，但深部地层基本平整；同时还发现了一些有封盖条件的远景构造。经过试验攻关，本文认为现有的MT法尚需作进一步的技术完善，同时应采用新的方法并依靠科研突破某些关键性技术，从而形成针对我国南方海相碳酸盐岩地层区油气勘查的有效的整体技术。
The marine--factes carbonate rock area in South China has good hydrocarbonpotential. However, conventional hydrocarbon exploration methods failed due tothe bad natural conditions. During the recent 3 years, electromagnetic methods(particularly magnetotelluric method) have been tested in this kind of area. The results indicate that the deep formations are mostly flat, although the surface naturalconditions are very complicated in the project area. Meanwhile, some hydrocarbonpotential structures with sealing conditions have been found in the area.Considering the special difficult circumstances in South China, the paper technically expounds the necessities of improving MT method and applying some newmethods and technologies which would be perfected on the basis of scientific research. Then there will be a complete technique system that favours hydrocarbonexploration in marine--factes carbonate rock area in South China.
