Abstract
A method for determining hydraulic fractures in the near-wellbore region, comprising the following steps: constructing a model with hydraulic fractures, a wellbore, and a formation as main components, and discretizing the model using non-uniform grid technology. This data subset is inverted using the time-lapse full-waveform inversion (TL-FWI) algorithm to achieve high-precision reconstruction of the hydraulic fractures and to obtain key attributes such as fracture-wellbore connectivity, extent of fracture propagation, and fracture geometry.
