北黄海盆地地震主要采集参数模拟
|
摘要
北黄海盆地地质条件相当复杂,前期采集的地震资料品质较差,信噪比低,中深层反射波组不明显,难以清晰反映盆地的构造形态。为了取得品质高的地震资料,采集参数的选择是关键,笔者利用Nucleus模拟系统,对气枪容量、沉放深度,电缆沉放深度等采集参数进行模拟、分析,结合海上地震采集参数试验,最终确定了北黄海盆地的采集参数,并获得较好的地震资料。
The geologic condition is very complex in the North Yellow Sea basin,the seismic data were characterized by poor quality ago,low signal-to-noise ratio,the reflection waves of the medium-deep layer aren't clear,they are not reflected structure of basin.In order to obtain good the seismic data,the choice of acquisition parameters are key.They use a simulation software,Nucleus,to simulate acquisition parameters,for example,capacity and depth of air sun,depth of cable,to combine test in marine seismic acquisition parameters,they confirmed the optimum parameters in the North Yellow Sea basin,and obtain quality data for production.
