摘要随着油气田勘探开发程度的逐渐深入，人们对精细地震勘探提出了更高要求，促使Walkaway VSP （后简称W-VSP）技术得到快速发展。通过吐哈盆地马朗凹陷马中地区M68井VSP数据处理实例，介绍了应用GeoEast软件处理系统对W-VSP资料的处理方法。根据数据自身的特点，采用三分量旋转、Tar补偿、波场分离等处理技术，针对低频信息采用具有良好保真性的处理模块，处理后的资料显示火山岩形态更清晰，波组强、弱关系更明显。与地面地震数据相比，W-VSP数据成像结果能更精细地刻画火山岩的形态，展示了W-VSP技术在地震勘探精细构造解释中的作用和发展潜力。

Abstract：As oil and gas field development intensifies gradually, people raise higher requirements on fine seismic exploration. The urgent demand for fine seismic exploration has promoted the rapid development of Walkaway VSP(W-VSP) technology. Through the VSP data processing case of Well M68 in the Mazhong area of Malang sag in Tuha Basin, this paper introduces the processing method of W-VSP data by using GeoEast software processing system. According to the characteristics of W-VSP data, highly effective processing techniques are adopted, such as three-component rotation,Tar compensation and wavefield separation. Processing modules with good fidelity to low-frequency information are selected. The processed data can display the morphology of volcanic rocks clearly, and the relationship between strong and weak wave groups is more obvious. Compared with surface seismic data, W-VSP data imaging results depict the morphology of volcanic rocks more finely. The study demonstrates the role and development potential of W-VSP technology in the fine structural seismic interpretation.

Key words： Walkaway VSP three-component rotation Tar compensation wavefield separation volcanic rock imaging
