The deep to ultra-deep platform margin reservoir is an important target of marine carbonate oil and gas exploration in continental basin, However, this kind of reservoir faces many challenges in prediction. This paper reviews the progress of geophysical exploration technology, such as seismic data processing, facies controlled reservoir prediction and other geophysical exploration technologies, and summarizes the application effects and limitations of geophysical prospecting technology reservoir prediction. The research shows that amplitude preserving and frequency extension, facies controlled inversion and other technologies have improved the accuracy of reservoir identification, but the exploration is still limited by the lack of seismic data quality, the uncertainty of geological model, and the inapplicability of geophysical exploration technology. To achieve breakthroughs in reservoir prediction accuracy, it is recommended to promote interdisciplinary collaboration, optimize acquisition parameters, refine the analysis of seismic response characteristics, and advance high-precision inversion technologies. Then improving the accuracy of reservoir prediction. The purpose of this study is to provide technical applications and development suggestions for further exploration and development in the field of deep ultra deep platform margin reservoir.
