开发地震在大庆长垣喇嘛甸油田储层预测中的应用
|
摘要
以喇嘛甸油田萨尔图油层为例,阐述了地震属性技术和重构地震反演的实践与应用。地震属性技术适合于刻画"泥包砂"型萨一组等的储层特征,尤其是井网控制程度较低的外扩区主河道预测。重构地震反演技术主要适用于高含水油田剩余油挖潜的研究,从而实现高精度井间砂体预测。研究认为,井震联合下的沉积相修正共归纳为河道侧积体、河道连续性(由连续变为间断、由间断变为连续)、河道规模(宽度、延伸长度、走向)、河道组合和河道期次5种模式。由此,利用测井曲线形态差异和高程差等特征,辅助反演切片研究河道垂向演化,最终确定单期河道边界。早期河道和晚期河道错综复杂叠置关系,构成了复杂剩余油空间关系,从而为下一步剩余油采出以及完善注采关系提供了良好的依据。
Taking Saertu oil layer of Lamadian oilfield as an example,this paper discusses the application of seismic attribution technique and curve reconstruction and inversion technique.Seismic attribution technique is suitable for describing characteristics of reservoirs such as Sa I layer with sandstone interbedding in mudstone,especially the main channel sandbody in area with sparse well control.While,curve reconstruction and inversion technique is suitable for highly accurate prediction of inter-well sandbody,thus is critical for tapping remaining oil in oilfield with high water cut.Based on sedimentary facies correction through log / seismic integration,5 models were built,including channel side accretion,channel continuity,channel size,channel combination and channel timing.Log differences and elevation changes are integrated with inversion slice to characterize the vertical evolution of channel sands and finally to determine the boundary of a single channel sandbody.The complex superimposition relationship between early channel sandbody and late channel sandbody determine the complicated spatial distribution of remaining oil.These understandingsprovide a solid basis for extracting the remaining oil and improving flood pattern.
