Research on Data Processing and Information Visualization Technology of Fractured Anticline Walkaway-VSP

The regional geological structure of the faulted anticline zone is complex, and the velocity difference is considerable. It isn’t easy to obtain accurate formation velocity, which seriously affects the accuracy of horizon calibration. The key to obtaining accurate velocity and precise calibration of geological horizons is how to deal with Walkway data and accurately correct the datum. The key to. Therefore, this study took the Houhe fault anticline structural belt in the Ludong area to sag as the target. The zero well-source spacing VSP logging was evenly distributed in the whole area. Parameters such as deconvolution and wave field separation were obtained, and the amplitude-preserved prestack was comprehensively applied. Well-control processing technologies such as denoising and OVT processing can obtain accurate velocity models, uplink longitudinal wave imaging, and datum correction to realize data information visualization and guide subsequent comprehensive research.
