The velocity inversion is the core technology of reservoir prediction. Various inversion software inversion methods are different, and thus have different application conditions and results. Grasping the adaptability conditions, advantages and disadvantages of all kinds of software, and choosing the inversion method suitable for the reservoir in the study area are the keys to reservoir prediction. In view of the existing speed inversion softwares such as Seislog, Strata, BCI, WCI, Jason and so on, starting from the principle and combining with the actual data processing and explanation, the advantages and disadvantages of various softwares and their adaptability are compared and analyzed; for different reservoirs or different Geological tasks, using different inversion methods, improve the quality of the retrieved data and the success rate of reservoir prediction.
