利用声速测井所得声速数值与地震勘探所得声速数值对比勘探天然气,经研究证实,是优越而可行的:在潜水面以下的诸地层中,其测井声速明显大于纵向地震声速的地层是气层,而纵向地震声速相同的连续延伸区域属于同一含气圈闭。
Comparing the sound velocity values obtained by sound velocity logging with the sound velocity values obtained from seismic exploration, the exploration of natural gas proved to be superior and feasible: the well logging sound velocity is obviously greater than that of longitudinal seismic sound velocity in all the layers below the diving surface , Whereas the continuous extension of the same seismic velocity in the longitudinal direction belongs to the same gas trap.
