Basing on the analysis and correlation of the7 wells , 8 seismic sequence boundaries are obtained by logging - seismic correlation , based on seismogram synthesis . more over , they can be traced in the studying region . the synchronic sequence stratigraphic framework is established finally 在單井分析和連井對比的基礎上,通過合成記錄標定、地震層序的分析,識別出8個三級層序界面,而且完成了全區的主干剖面解釋,建立了井震統一的等時層序地層格架。

When the hydrate saturation is less than the critical saturation : a ) the avo curve can indicate whether there exists any free gas below the bsr ; b ) if there is no free gas below , only when the micro model is model c can bsr be visible in seismogram 當水合物飽和度小于臨界飽和度時: a ) avo曲線能夠反映bsr下方是否含有游離氣; b )如果下方沒有游離氣,只有微觀模型為模型c時,在地震記錄上才有可見的bsr 。

( 4 ) wavelet was extracted through the theory of statistic of some trace data . the synthetic seismogram that is calculated by the convolution computation of the practical wavelet and reflection coefficient , matches with the seismogram beside the well better ( 4 )利用多道統計的原理求取地震子波,該實際地震子波與測井資料反映出的反射系數卷積出的合成記錄與井旁地震道最佳匹配。

While the hydrate saturation is more than the critical saturation : a ) the avo cannot curve indicate whether there exists any free gas below the bsr ; b ) the bsr is always visible in seismogram whether there exists free gas below or not 而當水合物飽和度大于臨界飽和度時: a ) avo曲線不能反映bsr下方是否含有游離氣; b )無論下方是否含有游離氣, bsr在地震記錄上總是可見的。

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 通過聲波模型和彈性波模型在直網格下的合成記錄與在曲網格下的合成記錄的比較驗證了方法的有效性與精確性。

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、合成記錄及層位標定、子波提取、初始模型建立、模擬退火反演和多參數約束條件的調整等。

Wavelet is extracted through statistic of some trace data , following the synthetic seismogram can be gained . finally the layer labeling can be realized 通過多道統計提取子波,合成人工記錄,實現層位標定,最終以可視化的形式顯示。

The record of the wave called a seismogram imprinted on paper , film , or recording tape or is stored and displayed by computers 稱作地震圖的震動波的記錄被刻錄在記錄紙、膠片或磁帶上,或者由計算機來儲存和顯示。
