In deep crust and mantle research,it is the main method to use OBS(ocean bottom seismometer) to receive refraction and reflection signal from deep structure,and then inverse the depth and velocity of deep structure by tomography.First break recognition is one of the most important steps in OBS tomography which directly determines whether you can get the correct structure.OBS simulation is an effective method which can provide guidance for first break recognition.This paper accomplished numerical simulation based on OBS using 2D sound wave equation according to the requirement of first break recognition,achieved common receiver gathers based on OBS with horizontal layered and dipped geologic model.By analyzing the reflection and refraction events in the OBS gathers of the two different models,we found some basic principle of first break recognition.The principle was also useful in practical OBS data processing which the data came from the OBS survey in Bohai Sea of China in August 2011.The research shows that the comparison among multi-OBS common receiver gathers is a simple way for first break recognition.First break presents symmetry if the geology model consists of horizontal layered medium and it is easy to recognize.It is more complicatod that first break recognition should use reflection and refraction events when encountering dipped geology model.
