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。

By analyzing the geological data and well be together with seismic. data from Penglaizhen gas pools in XC gas field of Sichuan, we set up the seismic response model of the gas-bearing sandstone and furtherpoint out the essential difference between gas-bearing sandstone and gas free sandstone. Therefore the a-bility to recognize gas pools has been improved. On the basis of these, we predict the gas-bearing sand-stone and obtain good results.
