本文简要地叙述了我们在南黄海盆地进行地震采集方法试验的情况,分析了各种采集参数情况下的资料质量,并讨论了各种采集参数对地震剖面质量之影响。由此作者认为,在一定地震电缆接受排列长度的情况下,加大气枪阵容积(即增加震源能量)和适当选择地震接受电缆的沉放深度,可以改善地震剖面的质量,增加对深层的勘探能力。在我们的240道电缆排列长度情况下,电缆沉放12m深度是合适的。如果要进一步改善地震剖面之质量,则必须增加地震震源之容积,即增加震源的能量。
This paper briefly describes the seismic acquisition method in the South Yellow Sea Basin, analyzes the data quality under various acquisition parameters, and discusses the effects of various acquisition parameters on the seismic profile quality. Therefore, the authors believe that increasing the air-gun array volume (ie increasing the source energy) and properly selecting the sinking depth of the seismic receiving cable can improve the quality of the seismic profile and increase the sensitivity to deep exploration ability. With our 240 cable lengths, a cable depth of 12 m is appropriate. If we want to further improve the seismic profile of the quality, you must increase the seismic source of the volume, that is, to increase the energy source.
