| 摘 要： | 南方海相勘探区地表普遍存在着碳酸盐岩裸露区的问题，而碳酸盐岩自身的物性条件严格限制了激发有效能量的产生、传播和接收，致使碳酸盐岩裸露区的地震资料品质大都很差。虽然影响碳酸盐岩出露区地震资料品质的因素很多，但激发能量的下传问题应该是碳酸盐岩出露区资料采集需要首先解决的问题。在研究碳酸盐岩激发原理的基础上，在地表条件允许的情况下优选可控震源激发及多井组合激发，可获取较高信噪比资料，这些采集方法均在南方碳酸盐岩裸露区的地震采集中取得了较好的效果。

| Abstract: | The southern area generally exist bare carbonate area. The physical conditions of carbonate rock strict limit the explosive efficient energy generation, transmission and reception, and leading to the bare carbonate area＇s seismic data very low in signal-to-noise. In the effect of carbonate outcropped area seismic data quality factors, energy transfer problem is the first problem to solve. Through the study of carbonate rock of the excitation mechanism, in permitting of surface condi- tions selecting controllable source can obtain relatively high SNR data Make full use of the successful experience that obtain a higher signal to noise ratio data in the loess plateau area by using the multi-well small explosives excitation, flexible appli- cation in carbonate outcropped area, looking for a way to suitable for carbonate outcropped area of excitation. |
