摘　　要：新场气田须家河组气藏属于深层陆相致密碎屑岩气藏,具有致密、低孔渗、薄层交互、多层叠置和强非均质性的特点,勘探成功率低,效益差。以高精度三维地震资料为主线,充分利用地震资料信息,多学科协同,深入研究了含气地震响应特征,并将AVO属性分析含气性检测技术运用在该气田须家河组气藏,取得了一系列油气勘探开发成果。As a tight clastic rocks reservoir in deep land-facies strata,Xujiahe gas reservoirs of Xinchang Gas Field is characterized by tightness,low permeability,thin inter-bed,multilayer nappe and high heterogeneity.These facts result in little profit and low success ratio of exploration.Therefore,by taking 3-D seismic data of high-precision as main line,making full use of seismic data and information,coordinating multidisciplinary,the gas-bearing seismic response characteristics have been studied in-depth.Besides,by applying the gas-bearing detection technology,analyzed by AVO(Amplitude Versus Offset) attributes,to Xujiahe gas reservoirs of Xinchang Gas Field,success in exploration and development had been achieved.
