摘要
渤深6探区高精度处理的目标带是T6以下的深层,由于这些地层埋藏较深且存在潜山、断裂带等复杂构造,造成深层能量较弱,成像困难.在该区块的高精度处理过程中应用能量补偿、频率控制、速度拾取、噪音衰减、剩余静校正等关键技术,解决了反射信号弱、分辨率低、信噪比低的问题,取得了较好的成像效果.
The objective regionof high-precision processing for Boshen 6 area is the deep layers below T 6 reflection. Because they are buried deeply and complex structures, such as buried hills, fracture belts, etc., existed, the signal from deep layer is poor and the energy is low. This makes the image of this area difficult. In the paper, we mainly applied energy compensation, frequency control, velocity picking, noise attenuation, residual static correction techniqueto resolve poor signal, low resolution and low S/N, and as a result good imaging was achieved.
