由于目标区周围数据覆盖不完全,因此井间地震的声波反演问题是非线性的(介质速度)和不适定的。鉴于这些事实,本文设计了一种新的根据井间地震数据对声波速度进行成像的非线性波形层析成像技术。
Because of the incomplete data coverage around the target area, the acoustic inversion of crosswell seismic is nonlinear (medium velocity) and ill-defined. In view of these facts, this paper presents a new nonlinear waveform tomography technique for imaging acoustic velocity based on crosswell seismic data.
