Abstract:The dipole shear wave can get the primary wave, shear wave and Stoneley wave in the formation, and the geophysical information obtained can be used to evaluate the anisotropy of formation, especially the anisotropy of oil-gas reservoir caused by fracturing, and to diagnose the formation reconstruction effect of fracturing operation. Contrasting the logging data of the dipole shear wave before fracturing with those after fracturing in oil-gas well of Ordos basin shows that the dipole shear wave crossing casing can be used to analyze the actual effect of fracturing. It will become a conventional logging technology to evaluate fracturing effect of oil-gas well and to detect cracks of oil-gas well.
