井孔与地面地震数据联合反演方法综述

传统的测井和地震资料宽带约束反演方法，存在着随井距增大插值误差增大的缺点，因此提出了能有效解决这一问题的井孔与地面地震联合反演（井地联合反演）方法。分别介绍了三维VSP方法、井间地震方法与地面地震方法进行联合反演的研究思路、处理流程及优缺点，并对井地联合反演的应用前景进行了展望。

Review of joint inversion methods for borehole and surface seismic data

Conventional well log-seismic broadband constrained inversion has the shortcoming that interpolation error increases with the distance of well spacing. Joint inversion of borehole and surface seismic, a new method to overcome this shortcoming, has been introduced. The paper discusses the technique routes, processing steps, advantages and disadvantages of 3-D VSP techniques, crosswell seismic technique, and surface seismic techniques. The application outlook of joint inversion of borehole and surface seismic data is forecast
