Abstract：In the process of efficient exploration and development of oilfields, it is urgent to improve the accuracy of reservoir description. Seismic inversion for reservoir description is a comprehensive oil and gas exploration technology, and its accuracy is affected by complex factors. Therefore, firstly, seismic inversion methods are introduced by classification, and their characteristics and advantages are clarified. Then, the inversion effect is analyzed by using field and synthetic data. Next, we explore the impact of technical links such as reservoir characteristic analysis, logging standardization, well seismic calibration, model construction, and seismic quality. The following conclusions are drawn: Reservoir characteristic recognition, inversion wavelet extraction, constraint model construction, and seismic data quality are the main factors affecting seismic inversion accuracy. In practical applications, it is necessary to carry out fine research on the main influencing factors, diminish the multi-solution property of reservoir identification, and improve the resolution of reservoir description, which is of great significance for the efficient and fine application of seismic inversion technology in oil and gas exploration and development.
