针对早期2D地震资料,采用组合静校正技术消除地表起伏影响,采用噪音压制技术消除各种干扰波,采用一致性处理技术保证能量均衡、消除闭合差,采用精细速度分析技术和偏移成像技术提高分辨率、达到最佳叠加和偏移成像效果。通过二次处理的2D地震资料偏移归位较准确,分辨率和信噪比得到明显改善,反射波组连续性增强,断裂断点更清晰,剖面能量一致性更好,为下步构造解释提供了可靠数据。 Aiming at the early 2D seismic data, the combined static correction technique is adopted to eliminate the influence of surface undulation, the noise suppression technique is used to eliminate various interference waves, and the consistent processing technique is used to ensure the energy balance and eliminate the closing difference. The fine velocity analysis technique and offset imaging technique are used to improve Resolution for best overlay and offset imaging. 2D seismic data offset by secondary processing is more accurate and the resolution and signal-to-noise ratio are obviously improved. The continuity of reflected wave group is enhanced, the fracture breakpoints are clearer and the energy consistency of sections is better, which explains the structure of the next step Provided reliable data.
