高分辨率地震野外参数的选取
|
摘要
野外地震资料采集的质量直接关系到地震勘探的成败。保证野外资料采集质量的关键是采集参数的选择。参数选择得当，就能有效地拓宽有效波频带范围，提高有效波的主频。以松辽盆地北部太平屯—宋芳屯高分辨率地震勘探区块的实际地质参数及相应的地震资料为基础，结合前人的工作经验，从地震波运动学的角度，确定了该地区高分辨率地震资料采集的参数，并分析了它对分辨率的影响程度。
The quality of field seismic data acquisition is crucial to the success of seismic survey, while the key to the high quality of field data acquisition is the selection of acquisition parameters. If parameters are selected properly, the effective frequency ranges can be broadened and the dominant frequencies can be improved. In this paper the acquisition parameters for high-resolution seismic survey in this area are determined in the view of seismic kinematics and the influences of each parameter on the resolution are analysed. On the basis of geologic parameters and corresponding seismic data from Taipingtun-Songfangtun high resolution area in the northern Songliao Basin. It is shown through its application in the field acquisition that the method is a successful one.
