印度尼西亚BINJAI沼泽区地震采集技术研究
|
摘要
印度尼西亚BINJAI区块地表广泛分布沼泽相,是典型的沼泽区。针对工区复杂的地震地质条件,提出相应的技术对策。首先对采集参数如采样率、道间距、最大炮检距、动校拉伸、速度精度、反射系数等进行了详细论证,根据论证结果选择观测系统进行资料采集,并对地震资料进行了相位、振幅、频率一致性处理,取得比较满意的剖面效果。
BINJAI of Indonesia is a typical swamp area,whose surface has many widespread swamp faces.We present some technological strategies for such complicated seismic geological conditions.We fully investigate such acquisition parameters as sampling rate,pitch,maximum offset,NMO stretch,velocity precision,reflection coefficients,etc.We then select a seismic geometry to collect data.We finally perform consistent processing for the phase,amplitude and frequency of these seismic data.Its profile effect is satisfactory.
