A seismic trace calculated from well-log data is called a synthetic seismogram . 由測(cè)井資料計(jì)算出來(lái)的地震記錄道稱為合成地震記錄。
The method of seismic and reflection wave synthetic seismogram in vti media 介質(zhì)中地震波反射波合成記錄的方法研究
The procedures are high - solution processing , synthetic seismogram and horizon calibration , wavelet extraction , initial model establishment , simulated annealing inversion , and adjustment of multi - parameters restraints 包括高分辨率處理、合成記錄及層位標(biāo)定、子波提取、初始模型建立、模擬退火反演和多參數(shù)約束條件的調(diào)整等。
This fact has an important implication for extension to 3d configurations . comparing the synthetic seismogram by using cartesian grids with the synthetic seismogram by using the curved grid , it can prove the approach is effective 通過(guò)聲波模型和彈性波模型在直網(wǎng)格下的合成記錄與在曲網(wǎng)格下的合成記錄的比較驗(yàn)證了方法的有效性與精確性。

百科解釋
A synthetic seismogram is the result of forward modelling the seismic response of an input earth model, which is defined in terms of 1D, 2D or 3D variations in physical properties. In hydrocarbon exploration this is used to provide a 'tie' between changes in rock properties in a borehole and seismic reflection data at the same location.
