高分辨率层序地层学在录井随钻对比中的应用
|
摘要
针对胜利油田东部井区受开发方式调整和油藏类型等因素影响,导致录井现场地层划分与对比难以满足精细勘探开发需求的问题,基于高分辨率层序地层学理论,对正钻井进行高分辨率层序随钻地层对比,将沙四上亚段划分为1个长期、3个中期、6个短期基准面旋回,从而建立了研究区的高分辨率等时地层格架,实现了地层层序的等时划分与对比。研究表明:中期基准面旋回的变化控制了砂体的叠加样式及横向展布,有利于录井现场地层的划分与对比;短期旋回基准面的升降变化控制了砂体的类型,是预测油气层位置的重要依据。研究结果对胜利油区地层分析和界面卡取等有一定的理论和实际指导意义。
It is difficult to achieve fine exploration and development by the field strata classification and correlation with mud logging while drilling due to the influences of development mode adjustment,reservoir type and other aspects in the eastern wellblock of Shengli Oilfield. High-resolution strata correlation with mud logging while drilling is implemented on the basis of high-resolution sequence stratigraphy theory. The upper sub-member of Sha4 formation is classified into 1 long-term,3 medium-term and 6 short-term datum cycles. A high-resolution isochronous stratigraphic framework for this area is established to obtain the isochronous classification and correlation of stratigraphic sequence. Research indicates that the medium-term datum cycles control the sandbody superimposition pattern and lateral distribution,which is beneficial to the field strata classification and correlation with mud logging while logging. The short-term datum cycles control the sandbody type,which is considered as an significant basis for hydrocarbon reservoir prediction. This research could provide certain theoretical and practical references for the stratigraphy analysis and interface identification in Shengli Oilfield.
