南黄海盆地地震试验数据处理分析方法与成果

PROCESSING METHOD AND RESULTS OF SEISMIC TESTING DATA IN THE SOUTH YELLOW SEA BASIN

摘要: 基于南黄海海相残留盆地的油气地震勘探,开展了针对性的沉放深度与枪阵组合的地震采集参数海上试验,对试验数据进行了子波特征、频带、能量、信噪比和F-K频谱的分析工作,制定了统一的处理流程,并进行了成像处理。在上述工作的基础上,对不同的试验参数进行了对比分析,优选了地震资料批量采集参数。

Abstract: For seismic prospecting of oil and gas in the marine residual basins in the South Yellow Sea, the testing for seismic acquisition parameters selection was carried out at sea, with emphasis on the sinking depth and combination of gun array. Image processing was made under a unified condition for the parameters of wavelet, frequency, energy, signal-to-noise ratio and F-K spectrum of the test data. Upon the basis, the parameters for data acquisition are optimized.
