在飞雁滩地区，根据地震波在上第三系中浅地层的砂岩中传播速度低于围岩，含气砂体在地震剖面上表现为亮点特征，结合沉积相分析及气藏描述技术，查明了本区的含气砂体，并进行了储量计算，取得了良好效果。
In Feiyantan area, the propagation velocity of seismic waves in sandstones in the middle and shallow upper Tertiary systems is lower than that of the surrounding rocks according to the seismic waves. The gas-bearing sand bodies are characterized by bright spots on the seismic profiles. Combined with sedimentary facies analysis and gas reservoir description, The gas-bearing sandbody in this area has been identified and reserves have been calculated, which has achieved good results.
