摘要
利用井间透射波旅行时,给出了一种以费马原理为基础的井间地震弯曲射线速度层析成象方法,数值计算表明了该方法比直射线法反演成象精度高。
A method of velocity tomographic inversion based on Fermat principle is presented by using travel times of transmitted waves from one borehole to another. The numerical comparison with the straight-ray method is performed, and shows that the precision of the method is high than that of the straight-ray method.
