裂缝性油藏三维定量表征技术在锦州南油田开发生产中的应用
|
摘要
在对渤海锦州南变质岩潜山裂缝性油藏地质、地震、测井综合研究的基础上,首次利用迭前地震反演横波阻抗做约束对裂缝发育的密度进行定量预测,以裂缝密度三维分布作为趋势约束,建立三维可视化的裂缝网络模型,并将离散的裂缝网络转化为定量化的三维参数模型。油藏三维定量表征结果成功应用于裂缝性油藏开发规律机理研究、随钻油藏方案优化研究及产能预测研究中。
Based on comprehensive study on geology,seismics and logging of Jinzhounan metamorphic buried hills fractured reservoir in Bohai sea area,for the first time,quantificationally forecast fracture density under the restriction of pre-superimposition seismic inversion.And then forecast the 3D distribute of the fractures according to fracture density distribution,make visible 3D fracture pieces model,finally transform the discrete fracture pieces into 3D continuous quantificational property models.3D reservoir quantitatively characterized results have been successfully applied to the fractured reservoir development law mechanism research,while-drilling reservoir plan optimization research and productivity prediction research.
