摘　　要：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。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
