Abstract
Abstract The exploration zone in Northwest China poses unique challenges due to its complex structures, fractured blocks, deep reservoirs, and geological anomalies. Conventional velocity modeling and migration imaging methods face difficulties in accurately imaging the underlying reservoirs beneath abnormal rock formations, resulting in poor signal-to-noise ratio and resolution. Moreover, the seismic data quality often falls short, leading to unfocused images. To address these challenges, we propose a novel approach: dynamic image warping-based reflection full waveform inversion. This method combines a model regularization strategy and structural constraints to generate high-resolution velocity models. The application in the Taha Industrial Zone demonstrates that the proposed method effectively characterizes the velocity characteristics of special geological bodies, such as deep weathering crusts, improving imaging effects and resolution, which allows for a more precise understanding of the complex geological features.
期刊介绍:
Journal of Geophysics and Engineering aims to promote research and developments in geophysics and related areas of engineering. It has a predominantly applied science and engineering focus, but solicits and accepts high-quality contributions in all earth-physics disciplines, including geodynamics, natural and controlled-source seismology, oil, gas and mineral exploration, petrophysics and reservoir geophysics. The journal covers those aspects of engineering that are closely related to geophysics, or on the targets and problems that geophysics addresses. Typically, this is engineering focused on the subsurface, particularly petroleum engineering, rock mechanics, geophysical software engineering, drilling technology, remote sensing, instrumentation and sensor design.
