摘　　要：VSP检波器埋置在井中,它包含了深度与地层中的速度信息,因此VSP是地震、测井和地质信息的标定和转换的重要桥梁之一。但VSP不具备地面地震规则和均匀的观测能力;此外,由于VSP的专业性和特殊性,使VSP未能有效地发挥其信息标定和转换的桥梁作用。本文通过改进VSP处理软件设计,使其能通过空间坐标(x,y,z)驱动VSP数据处理与显示,并能在不同空间与地面地震、测井和地质信息建立更直接和直观的联系,同时达到界面友好、快捷的目的,更好地发挥VSP与其它数据间的标定和信息转换的桥梁作用。Because the VSP geophone is set in the well, VSP data include the information of the measured depth and formation velocity. Therefore, VSP is one of the important bridges to connect the data in time domain with those in the depth domain, such as seismic, well logging and geological data. But VSP＇s geometry is not as regular as surface seismic. This limits the ability of VSP to image the geological body in the subsurface. In addition, VSP cannot effectively play its role in data calibration and conversion because of the professional and the particularity of VSP. This paper introduces a good software design for VSP processing. It can use the coordinate （x,y,z） to drive the VSP processing and displaying. It also acts as the connection among the seismic, well logging and geological data that are in different domain. Moreover, it is user-friendly and convenient. All of these features will greatly improve the VSPrs role in data calibration and conversion.
