摘　　要：百色盆地那坤地区地处南方丘陵山区，地表条件复杂，地震资料采集效果不理想。针对该区地震反射资料信噪比较低、地质构造复杂的特点，开展三维地震资料目标处理提高地震资料品质，在此基础上采用多种地震技术进行构造精细解释工作。结果表明：该区地震资料品质有明显改善，构造格局得到了进一步落实，发现并落实了一批有利圈闭，在K12块东部部署探井获得工业油流，为那坤地区的滚动勘探开发提供了技术支撑。Nakun region in Baise Basin is located in the hill and mountain area of South China, which is character- ized by complex surface conditions and non-ideal gathered effects of the seismic data. In the light of the featrues of lower signal-to-noise ratio of seismic reflection data and complicated geological structures, the conducted target processing for the 3 D seismic data improves the quality of the data. On the basis of the above, many kinds of seismic techniques are adopted for the fine interpretation of the structures. The results show that the seismic data quality has obviously improved, the structure framework is further ensured, and moreover a series of favorable traps are discov- ered and made clear. In addition, the commercial oil flow is obtained in the arranged exploring well in East Block K12, thus the achievements have provided technical support for the progressive exploration and development in Nakun region.
