【摘要】 随着勘探程度的提高,吉林探区的地震采集转向了岩性油藏、隐蔽油藏他和深层火山岩勘探,要求地震采集资料要有较高的分辨率和精度。而由观测系统设计参数产生的采集脚印及激发接收条件差异产生的子波不一致,影响了采集中处理精度的提高和解释中地震属性的精度提高。因此,从影响子波一致性的原因入手,从观测系统设计、激发和接收因素的选择上加以分析和研究,提出了减弱影响子波一致性的技术方法,在很大程度上提高了复杂地表的地震采集资料品质。更多还原

【Abstract】 Improving the prospecting program,seismic acquisition of Jilin prospect area turns to lithologic deposit,elusive reservoir,deep volcanic layer prospect.It requires more resolution and accuracy.Because of the recording geometry causes footprint and different conditions of the shot and receive cause the different wavelet,hold up the advance of processing accuracy degree and seismic attribute accuracy degree of seismic interpretation.So the paper raises a kind of method to abate the effects of the wavelet community by studing the factors of the effects of the wavelet community and analyzing the design of recording geometry and the factors of shot and receive.It will advance the quality of seismic data quietly.更多还原
