摘　　要：COBEN叠前储层反演及气藏烃类检测技术基于俄罗斯科学家В·П·Сибиряков所提出的离散介质地球物理模型。该技术最大的特点是,在无井约束的前提下,利用叠前地震资料进行特殊处理,从中反演孔隙度、AVD异常、DR等能反映储集层物性和含油气性的参数,再利用以上参数有效地开展储集层物性预测研究。利用此技术对川东北地区渡口河、七里峡、菩萨殿、五宝场、杨家坪、罗家坝、东升地区测线进行储层预测及气水识别,与井对应情况良好,区域预测已在七里北地区得到证实。该技术是气层预测行之有效的方法。The technique of COBEN prestack reservoir inversion and gas reservoir hydrocarbon detection is based on discrete media geophysical model proposed by Russian scientist В.П.Сибиряков.The greatest peculiarity of this technique is that the prestack seismic data is specially processed under the prerequisite of no well constraint, from which the porosity, AVD and DR anomaly etc. capably reflecting parameters of reservoir physical property and oil-gas-bearing nature, are inversed; and again the reservoir physical property prediction research effectively launched by using the above parameters. This technique is utilized to conduct reservoir prediction and gas-water discernment for survey lines of northeast Sichuan areas as Dukouhe, Qilixia, Pusadian, Wubaochang, Yangjiaping, Luojiaba and Dongsheng etc. fairly corresponding to the well circumstances, and the regional prediction has been confirmed in north Qili area. This technique is an effectual method in gas-bearing formation prediction.
