海上压缩感知地震仿真采集设计与处理

压缩感知地震采集的主要目的是提高地震采集效率，降低地震采集成本。受现有海上地震采集装备及技术限制，目前只能在某些方向上进行压缩感知随机采样。通过研究，形成了一套基于Jitter模式的海上压缩感知地震采集观测系统设计技术及配套的数据重构方法和模块。利用该方法实施了两个海上压缩感知地震采集设计仿真试验，并对所采集数据进行了重构处理。结果显示，在节省约1/3采集资源情况下，模型正演数据和实际数据仿真试验的重构效果良好，表明Jitter随机采样模式适用于海上压缩感知地震采集观测系统设计。

A simulation of acquisition design and data pro-cessing for offshore compressive sensing seismic

Compressive sensing seismic acquisition aims at more efficient operation and cost reduction.Due to offshore equipment and technical limitations,compressive sensing random sampling may only be performed in some directions.We develop a Jitter-based system for offshore compressive sensing seismic acquisition geometry design and supporting modules for data reconstruction.We accomplish compressive sensing acquisition design for two offshore surveys and subsequent data reconstruction.The results show that data reconstruction,both for synthetic data from forward modeling and real data simulation,yields good results; whereas,acquisition cost is reduced by 1/3.This means that Jitter-based random sampling is feasible for offshore compressive sensing seismic acquisition geometry design.
