摘　　要：高分辨率地震勘探方法在当前地震勘探中的作用已日见重要。本文依据松南地区开展的高分辨率地震勘探试验和研究工作，介绍了高分辨率地震勘探各个环节的方法技术，数据采集中要着重提高信噪比和分辨率．注意保持频宽和高频成份的能量；数据处理采取了高精度静校正、高保真去噪和高保真拟合等方法，保证资料有高信噪比和高分辨率。通过上述措施，最终得到了较理想的高分辨率地震剖面，High resolution seismic prospecting methods become more and more inportant in currentpetroleum exploration, This paper introduces some methods and techniques of each link in high resolutionseismic prospecting in accordance with testing and research work carried out in the southem SongliaoBasin. In data acquisition, Attentions are paid to preserve frequency bandwidth and energy of high free-quency components. Data processing includes high-precision static correction ,high-fidelity noise elimina-tion and high-fidelity fitting.These measures ensure that the seismic sections obtained have high signal-to-noise ratio and resolution.
