摘　　要：莫北油田莫116井区下侏罗统三工河组二段(J1s2)构造复杂,油藏认识不清。为合理有效开发该油藏,在精细标定、高密度解释的基础上,针对J1s2对应地震同相轴存在错断、挠曲、产状变化或地层缺失现象,进行小断层解释,同时应用地层倾角扫描、断棱检测、相干体技术分析断层平面展布及组合关系,并结合钻井生产特征,进一步确定控藏断裂将莫116井断块、莫122井断块细分割成7个小的断块,每个断块有各自的油水系统。The structure of J 1 s 2 reservoir in Sangonghe Formation of Jurassic in Wellblock Mo 116of Mobei Oilfield was complex and reservoir clarification was not clear.In order to develop the reservoir rationally and effectively,on the basis of the fine calibration and high density interpretation of target zone,in view of the leap,distortion,occurrence changes of the seismic reflectors,the minor-fault is interpreted.The combination relations of coherent volume,map analysis technique such as dip angle scanning,edge detection,fault trend are interpreted and characterized.In combination with well production performance,the reservoir controlled fault should be further determined to subdivide Fault Blocks Mo 116and Mo 112into 7small fault blocks,each block has its own oil and water system.
