【摘要】 为了解决YGH盆地纵波勘探中遇到的难题 ,在该盆地 4个构造上开展了多波地震勘探工作。多波地震不但能够有效地、很好地解决构造勘探问题 ,而且能够准确地预测出气层和含钙层。钻井证实 ,利用纵横波振幅比和速度比预测浅层气层的方法是完全正确的、可行的更多还原

【Abstract】 In order to solve the problems encountered in P wave exploration in YGH Basin,multi wave seismic exploration has been performed on four structures of the basin.Multi wave seismic can be used not only for structural exploration,but also for accurate prediction of the gas zones and calcic formation.According to the drilling results,it’s proved to be correct and feasible,which use amplitude ratio of P wave,S wave and velocity ratio to predict gas zones in shallow formations.更多还原
