摘要
随着宽方位采集方法在海上的成功应用和实施,宽方位采集观测系统在识别裂隙的能力、成像分辨率、空间连续性、衰减相干噪声和多次波等方面具有明显的优势,是陆上岩性、振幅变化、各向异性和小断裂油气藏地震勘探首选的采集观测系统。通过对当前宽方位地震采集方法的文献调研和分析,以及对当前沙特阿美公司野外地震陆上、过渡带宽方位采集所采用方法的分析研究,提出了当前宽方位采集所采用的设计方法,对其所采用的观测系统参数和属性进行了分析。沙特MK地区采用宽方位采集方法得到了较好的地震采集资料,局部构造成像更清晰,断裂分界面更为明显。
With the success application and practice of wide azimuth collecting means in offshore,wide azimuth observation system has shown its advantage in identifying fissures,imaging resolution,space continuance,damp coherent noise and multiple wave,which is the best collecting observation system for seismic exploration in land lithologic and amplitude change,nonisotropy and little fault reservoirs.By means of the tracking and analyzing,the wide azimuth technique was applied in land and transition belt with field seismic in Saudi Aramco,and then wide azimuth geometry was proposed with the observation system parameter and attributes analysis.A project,which was conducted with wide azimuth,was introduced in MK in Saudi Arabia.With the development of equipment, high density 3D wide azimuth acquisition or super 3D acquisition will be possible and will be put into practice in the future.
