| 摘 要： | 已有的资料显示，台格庙地区上古生界地层具有较好储气潜力，根据差异层速度分析（DIVA）对含气地层较为敏感的特点，对区内储层作了预测。先利用地质和测井资料确定出用于DIVA分析的背景层速度，然后利用逆Dix公式预测出底界面地层均方根速度，再沿每一条地震测线方向和整个工区平面，作实际地层底界面均方根速度与预测底界面均方根速度的差值，进而在工区内预测岩性和储集体的横向展布范围。

| Abstract: | Previous results show that the late Paleozoic strata are the favorable prospects of gas in Taigemiao area. Differential interval velocity analysis (DIVA) is sensitive to gas-bearing strata. The background interval velocity for DIVA was determined with geological and well logging data, and the root mean square velocity of bottom stratum was calculated by reverse Dix formula. Difference between the observed and predicted RMS velocities of the bottom stratum was extracted along seismic line and extrapolated to the whole work area. The results were used to predict the lithology and distribution of reservoir. |
