According to practical needs of acoustic remote detection logging,the present paper investigates the influences of source frequency,reflection interface position,interface dip and dipole source orientation on S-wave reflection amplitude by using an accurate 3D finite difference numerical simulation method.Analysis results show that the operating frequency of the dipole S-wave remote detection instrument should be below the cut-off frequency of flexural wave,so as to enhance the amplitude of the reflected signal from formation reflector relative to that of the direct flexural wave along borehole.It is recommended that the data acquisition tool should have a source-to-receivers offset less than 4 m in order to effectively image a formation reflector with a dip angle in 40°-90° range.
