【摘要】 目前,全球面临资源紧缺问题,石油资源表现尤为突出。随着油气开发难度越来越大,油田企业高投入、高消耗使得开发成本难以控制,这就迫使油田企业苦练内功,加大管理力度,向“边、老、贫、深、难”油藏进军。二维模式下的油藏管理,不能直观、形象化地展示和描述地形、油井、地层之间的空间分布关系,这就不能为加密井的布设、寻找剩余油等提供便捷、科学的参考依据。论文以吴起采油厂柳沟油田作为研究区块,利用GIS、3D GIS技术思想,借助全球领先的Skyline技术平台,在收集地形数据、油井数据、钻井资料、地质资料、地层数据以及其他一些辅助说明资料的基础上,完成了地形、油井、地层等建模,通过程序编写将模型及相关信息集成在Skyline软件平台里,最终完成柳沟油田三维可视化油藏管理的研究目标,使得柳沟油田油藏管理立体化、形象化、三维可视化。主要成果有：(1)构建地形、油井空间轨迹和地层模型通过构建DEM的思想,融合卫星遥感影像,完成了柳沟油田的三维地形模型；结合油井的井斜数据、井深数据、测井解释资料等信息,完成了油井的三维空间轨迹模拟成果；根据地层的古海拔、井钻遇地层信息,通过四边形网格构模方法完成了地层模型的建立。(2)油藏管理多源信息的集成表达Skyline三维可视化技术平台,借助其优势特点,完成油藏管理涉及到的多源、异构数据的集成与三维可视化展示工作,实现了将离散的数据集成起来,更好地服务于油藏管理。(3)完成地上地下一体化研究成果的三维可视化展示通过油井的井口坐标和地下油井模拟,把油井地表分布状况和地下空间展布结合在一起。在三维可视化平台里,将两者一体化地展示出来,便于油藏管理技术人员建立整体认识,提高管理效率。更多还原

【Abstract】 At the present time,the world is facing the problem of resources shortage,which is the oil in especial.As the oil development are tending more and more difficult.High input and high consumption of oil companies make it difficult to control development costs.So that,it has forced the oil companies have enough skills and enhance its management to carry forward into the "edge, old, poor, dark, difficult" reservoir. Two-dimensional model of reservoir management, which can not offer intuitive, visualization display and description of the topography, wells, stratigraphic relationship and the spatial distribution,can not conducive to provide convenient, scientific basis for encrypting well,looking for the remaining oil,and so on.The paper, which chooses Wuqi oil production Liugou oilfield as a research district,uses the ideas ofGIS、3D GIS technology,the worldwide leading technology platform—Skyline,includes many contents,such as collection of terrain,well, drilling,geological data and stratigraphic data. On the basis of these data,the paper has finished the terrain,oil wells and stratigraphic modeling.Models are integrated in the Skyline by programming.Full use of the Skyline’s Top-quality technology,the paper has completed three-dimensional visualization of the liugou oilfield reservoir management,it can make reservoir management three-dimensional,visual and specific. Main achievements are as follows:(1) Constructed the terrain, well trajectory and formation modelsWith the idea of construction of DEM, merged remote sensing images,the paper completed the three-dimensional terrain model of Liugou oilfield;Combination of the well deviation data,depth data,log interpretation data and other information,the paper completed a three-dimensional trajectory simulation of the well results;Under formation ancient sea level,drill drilled strata information,through the quadrilateral grid modeling method,the paper completed formation model.(2) Integratd the multi-source information of reservoir managementSkyline’s 3D visualization technology platform, with its characteristic advantages, completes reservoir management,which involves in multi-source, heterogeneous data integration and visualization present their realized,integrates the discrete data.It can offer a better serve to reservoir management.(3) Completed three-dimensional visual display of above and below ground resultsThrough wellhead coordinates and underground wells simulation,the paper links distribution of oil well surface and underground distribution together. In the three-dimensional visualization platform,the paper integrated of the two display,it is easy for reservoir management technical staff to know overall understanding of the establishment,and improve management efficiency.更多还原
