| 英文摘要 | Based on the 3-D acoustic equation and Tarantola's generalized inversion theorem, taking into consideration the character of cross-well survey, a 2.5-D cross-well waveform tomography method in the frequency domain is presented here. The experimental results of the numeric models show that this method can achieve a resolution for the thin horizontal layers up to 1/4 of the dominant frequency wave length, and its resolution is obviously higher than the travel-time tomography, especially the vertical resolution is substantially improved. The anti-noise tests with synthetic data show that the random noise affects slightly the quality of the waveform tomography in the case of N/S=0.8, but the coherent noise affects greatly, especially the strong amplitude disturbance near the first-arrival has a serious effect. The waveform inversion result of practical data shows that the waveform tomography can depict the distribution of the cross-well medium's property and the reservoir connectivity, and is of importance for oil development. |
