地震断裂检测技术在塔河油田南部碳酸盐岩储层及油藏预测中的应用
|
摘要
塔河油田南部奥陶系一间房组碳酸盐岩储层具有油层薄、油水关系复杂及断层控储、控藏的特征。应用地震资料进行断裂检测的准确与否,关系到断控型油藏预测的准确度,决定了本地区的勘探开发的成效。基于塔河地区高品质二次采集三维地震资料,应用精细相干及蚂蚁体断裂检测技术对南部斜坡区断裂进行了检测。参考检测结果,结合地震剖面对断裂开展了精细解释,将解释断层平面多边形与碳酸盐岩储层预测振幅变化率属性进行叠合,在此基础上开展了断控型油藏预测研究,总结出塔河油田南部地区两种与断裂相关的油气富集模式:主干断裂上倾封挡型和分支断裂上倾封挡型。按此模式部署,在该区取得了较好的勘探开发效果。
The Ordovician Yijianfang carbonate reservoirs in southern Tahe oilfield are characterized by thin oil layer,complicated oil-water contact and control of fault on reservoir and hydrocarbon accumulation.The accuracy of seismic fault detection determines the accuracy of prediction of fault-controlled reservoir and the effects of exploration and deve-lopment.Based on the new reacquired high quality 3D seismic data,the Eigen coherent and ant tracking techniques are applied to detect faults on the south slope.The results of detection are combined with seismic profiles to perform fine interpretation of faults.The interpreted plane fault polygon is overlaid over the amplitude variation rate map from carbonate reservoir prediction to perform prediction of fault-controlled reservoirs.Two types of hydrocarbon enrichment patterns associated with fault are identified in the southern Tahe oilfield,namely major fault up-dip sealing type and branch fault up-dip sealing type.Exploration and development programs deployed according to these two patterns are successfully.
