The paper concentrates on seismic wave - field forward modeling and migration for the fractured reservoir. it researches the wavefield extrapolation operator for lateral variation of velocity, design four theoretical models and seven practical models with fracture and cavity. base on the progenitor, in the frequency - wavenumber domain with the pspi wavefield extrapolation operator and arithmetic of forward modeling and migration that applied lateral variation of velocity which is strong, the paper obtains the result of numerical simulation and the wavefield characteristic by the way of the forward modeling and depth migration of poststack seismic wavefield
本文圍繞縫洞儲層地震波場正演與偏移問題，研究了適用於橫向變速波場延拓運算元，建立了四個理論的縫洞模型和七個實際的縫洞模型，在總結、分析前人的研究成果的基礎上，利用適合橫向速度劇烈變化的相移加插值的波場延拓運算元，在頻率?波數域對上述的地質模型進行正演、偏移處理，最後得到了縫洞儲層地震波場的一些特徵。 -
Based on the commonly used strip theory with the extension of taking into account the instantaneous variation of the wetted hull surface during the motion and its effects on the ship hydrodynamic characteristics, this dissertation mainly calculates the ship motions and loads in waves in time domain and elementarily investigates some nonlinear characteristic of ship motion and hydrodynamic coefficient. it is hoped that the research had an engineering value for the predication and evaluation of seakeeping performance in the concept ship design stage
