本文通过对四川XC气田蓬莱镇油气藏的地质和测井资料结合地震资料的分析，建立了该气田含气砂体的地震响应模式，并进一步指出了含气砂体与不含气砂体的本质区别，提高了对气藏的识别能力。在此基础上，对含气砂岩进行了预测，取得了良好的效果。
In this paper, the seismic response model of gas-bearing sandstone in gas field in this gas field is established based on the geologic and well logging data of Penglaizhen reservoir in XC gas field in Sichuan and the seismic data. The gas-bearing sandbody and gas-free sandbody Essential difference, improve the ability to identify gas reservoir. Based on this, the gas-bearing sandstone has been predicted and achieved good results.
