【摘要】 大庆长垣油田开发至今已进入高含水开发阶段,传统意义的油藏技术已经不能满足现今油田实际的需求,为此,本文总结了井震联合多学科油藏描述技术,并阐述了其在长垣高含水油田开发的应用及效果.井震联合多学科涵盖了井震联合构造解释、井震联合储层解释技术、井震联合砂体雕刻及剩余油预测和地震约束储层地质建模技术.其中,井震联合构造解释技术主要包括小尺度构造解释、低级序小断层识别和组合、高精度速度场建立和井间微幅度构造,为一套适用于大庆长垣密井网构造解释的配套技术;井震联合储层解释技术阐述了二个核心技术——地震属性技术和重构地震反演技术,分析二者在长垣密井油田的应用与限制,地震属性技术适用于舍气边界识别和河道砂的识别,地震重构反演适用于密井网储层精细刻画.在此基础上,以大庆长垣油田为例,应用井震联合多学科油藏技术在断层变化大的区域进行注采调整和水平井设计,并取得了较好的效果.更多还原

【Abstract】 Daqing Changyuan oilfield has been reached the stage of high water cut.Traditionally reservoir technology cannot meet the actual needs of present oilfield.This paper presents a multidisciplinary wells and seismic reservoir description in the application of Changyuan high water oilfield development.Well-seismic combination multidisciplinary covers well-seismic structural interpretation,reservoir wells and seismic interpretation techniques,well seismic joint sand sculpture and remaining oil prediction,seismic restraint reservoir modeling techniques.Well-seismic combination structural interpretation techniques include small-scale structural interpretation,lower sequence and combination of small fault identification,establishment of high precision velocity field,inter-well microamplitude structures.These are a set of complementary techniques suitable for dense well structural interpretation of Daqing Changyuan.Well-seismic interpretation techniques elaborated two reservoir core technologies—seismic attribute technology and reconstruction of seismic inversion technologies.Applications and limitations of two technologies are analyzed in Changyuan dense oil wells.Seismic property technology is applicable to the recognition of gas-border and the identification of river sand.Seismic reconstruction inversion is suitable for fine reservoir characterization of dense well.On this basis,this paper takes Daqing Changyuan Oilfield as an example,well-seismic combination multi-disciplinary reservoir injection technique is applied to carry out injection adjustment and horizontal well design in the region which fault varies largely,and achieved good results.更多还原
