井间地震数据的波动方程偏移成像

Aiming at the defects of cross-well imaging,combined with the characteristics of cross-well seismic data,a cross-well seismic reflection migration imaging technique was developed by utilizing the up-going and down-going reflection information.The technique has considered the kinematics characteristics(time information)and the kinetics characteristics(amplitude information)of cross-well data.Taking PC group as calculation platform and Linux as operation system,the workflow of parallel computation was developed.The technique and computation program were tested and preprocessed on 64 bit Lianxiang computer group by using cross-well model data and actual data from one oilfield.The results show that the method and parallel computation is correct and feasible,and has high computational efficiency.
