Unlike the conventional seismic acquisition, simultaneous-source acquisition allows the overlap in the record, which can enhance acquisition efficiency and improve image quality. To further explore the advantage of simultaneous-source technology, a double blending survey is proposed, which contains the self-interference and cross-interference. In the designed survey, the self- and cross-interference are controlled by two factors (inline shot interval and source number). When the inline shot interval is larger than the efficient record length (ERL), the blending scheme is degraded to the cross simultaneous-source survey. When the source number is equal to one, the blending scheme is degraded to the self simultaneous-source survey. To suppress intense hybrid interference, the mixed regularization term integrating sparse constraint and rank reduction constraint is applied to provide stronger regularization ability. Compared with the individual penalty term, the mixed constraint can further suppress hybrid interference and obtain better deblending performance. Deblended results on synthetic and field data examples confirm the performance of mixed constraint and demonstrate that the designed hybrid simultaneous-source survey can further enhance the efficiency of acquisition.

混合同时源数据的去混合

与常规地震采集不同，同源采集允许记录重叠，提高采集效率，提高图像质量。为了进一步挖掘同时源技术的优势，提出了一种包含自干扰和交叉干扰的双重混合调查。在设计测量中，自干扰和交叉干扰受两个因素（在线炮弹间隔和源数）控制。当在线拍摄间隔大于有效记录长度（ERL）时，混合方案降级为跨同时源调查。当源数等于一时，混合方案降级为自同时源调查。为了抑制强烈的混合干扰，采用融合稀疏约束和降秩约束的混合正则化项，提供更强的正则化能力。与单独的惩罚项相比，混合约束可以进一步抑制混合干扰，获得更好的去混合性能。合成和现场数据示例的去混合结果证实了混合约束的性能，并证明所设计的混合同步源调查可以进一步提高采集效率。
