Abstract The authors designed the observation system in favor of the reflection wave imaging in Yongxin area, applied the least square conjugate gradient method to tomographic inversion, and obtained the velocity of the crosswell reflective wave imaging. The VSPCDP imaging and Kirchhoof migration method were employed to get the fine profile of the upgoing wave. The crosswell profile reflects abundant layer information, and the result has solved the problem of the oil and water connection.
