Single-well shear-wave imaging by a borehole dipole source, a dipole shear-wave far-detecting technique, emerged in recent years as an important geophysical well-logging method. It has obvious advantages compared with previous monopole reflected P-wave method, and greatly improves our ability to detect geological structures away from borehole. The technology not only can determine the space position of reflector, and can get the strike of the reflector through rotating four component data. This paper provides a review of the single-well imaging technology with emphasis on the dipole shear-wave imaging. It elaborates the theoretical basis and data processing method of the shear-wave imaging using borehole dipole source, points out some advantages of dipole acoustic reflection imaging technology. We formed a fast and effective dipole shear-wave far detection imaging work procedure, and used the field data processing examples to demonstrate the advantages of the dipole shear-wave imaging. The field data processing results demonstrate that the dipole shear-wave imaging technology can effectively detect the borehole geologic structure in reservoir and meet the needs of field data processing. The processing techniques are reliable and effective. For unconventional reservoirs, such as tight sandstone and carbonate reservoir, the technique is also effective. It can provide technical support and basis for further fine exploration and development of reservoir structure.
