Abstract

Based on the research of equal depth streamer and variable depth streamer,we analyzed the seismic spectrum,seismic fidelity preserving,rock physics,pre-stack inversion and so on.And we study the seismic well material and the seismic profile.The result suggests that the variable depth streamer has the feasibility of inversion work,and the seismic inversion of the variable depth streamer has higher precision.The variable depth streamer seismic has a greater advantage in identifying reservoir thickness,predicting physical properties and so on,also,it is rich in low-frequency information.It is conducive to carry out pre-stack inversion work,help to get a richer geological understanding.
