【摘要】 二叠系长兴组生物礁是建南气田主产层之一。生物礁生长环境的特殊性使其在地震响应上有着与围岩完全不同的特征,根据这些特征在研究区内寻找类似异常。通过沉积相、地震相、神经网络模式识别以及AVO(Ampli-tude Various with Offset)响应特征的分析,认为三星伴月异常体为生物滩的异常反射,有待钻井证实。更多还原

【Abstract】 Organic reef in Permian Changxing formation is one of the main Pay zone in Jiannan gas-field.Because of its specialty of development environments,organic reef has different seismic response characteristics comparing with surrounding rocks.According to these characteristics,the similar abnormity will be found in the research area.After analyzing sedimentary faces,seismic faces,NN(Neural Network) pattern identification and AVO response,"SXBY" abnormity is regarded as the abnormal reflection of organic bank,which will be proved by drilling.更多还原
