【摘要】 针对斜井的合成地震记录 ,本文提出了一种简便、实用的制作方法 :1根据井斜角、方位角和测量深度 ( MD)计算测量点偏离井口的 Δ x、Δy和真垂直深度 ( TVD) ;2在 TVD域内利用常规方法制作合成记录 ;3将合成记录和测井曲线沿井孔显示 ,同时考虑井孔方位与地震测线间的关系 ;4对合成记录进行微调 ,以使合成记录能更好地匹配地震剖面。采用上述方法制作的斜井和水平井的合成记录和地震剖面对比较好 ,达到了斜井层位标定的目的更多还原

【Abstract】 The paper presented a simple and practical method aimed at making inclined well synthetic seismogram: ① calculating intervals Δx, Δy drviating measurement station from wellhead and true vertical depth (TVD) according to angle of well deviation, azimuth and measurement depth (MD); ② making a synthetic seismogram using conventional technique in TVD domain; ③ displaying the synthetic seismogram and logging traces along the well and considering the relation between the borehole azimuth and the seismic line at same time; ④ finely adjusting the synthetic seismogram so that the synthetic seismogram matching seismic profile better. Synthetic seismograms of inclined well and horizonal well made of above mentioned method have good correlation with seismic profiles and achieve the aim of bed marking for inclined well.更多还原
