摘　　要：我国南方碳酸盐岩广泛分布,具有巨大的油气资源潜力和勘探前景.全国油气资源战略选区调查与评价项目选择我国典型南方海相碳酸盐岩裸露区开展地震勘探技术攻关.针对该区地表灰岩普遍出露、激发弹性波能量转换少、散射噪音干扰严重等勘探难点,研究和应用了"宽线+折线"地震采集技术和与其配套的拟三维地震处理技术,能较好地压制噪音,提高剖面信噪比,在主要目的层得到了较好的成像效果,桂中1井钻探结果与地震勘探解释成果吻合较好,检验了该方法用于南方碳酸盐岩地区勘探的有效性.Carbonate rocks are widely distributed in South China, with huge potenna, dnu prospects of the oil and gas resources. The State Proiect o{ Strategic Area Survey and Evaluation for Oil and Gas Resources conducted a study of seismic exploration technology in the carbonate outcrop areas in South China. Aiming at the difficulties of seismic exploration in the areas, we made the proper technical strategies and operational techniques. Wide-crooked line seismic acquisition and the corresponding pseudo-3D seismic processing techniques were developed in thisstudy. Satis{actory seismic data were acquired,and the well data of Guizhong 1 demonstrated the seismic survey results.
