查询词典 constrained minimization

Therefore, local wave decomposition technology was introduced into the logging date extrapolation method constrained by time-phase model to gain the seismic instantaneous phase. The relationship of logging and seismic data was established through the wellside strata correlation. High resolution attributes inversion profiles were generated through the extrapolation of logging constrained by equiphase surface established based on seismic data.
