江苏瓦庄油田油藏数值模拟开发技术政策界限研究

针对江苏瓦庄油田窄条状、长井段、多油层、薄互层、多断层的特点,采用地质建模和油藏数值模拟一体化的技术思路,在构造研究、精细地层对比、沉积相分析和测井分析的基础上,建立了三维油藏地质模型,以该模型为静态地质模型进行精细油藏数值模拟研究,在历史拟合成功的基础上,进行了开发层系、油井距断层距离、分层配注的开发技术政策界限研究,得出了该类油田合理的开发政策,为油田的开发生产提供了合理的理论指导。

Production technology policy limitation study by integration of 3D geologymodel construction with reservoir numerical simulation in Wazhuang oil field, Jiangsu

In terms of the characteristics of slender shape, long borehole segment, multi-oil layers, thin intercalated layers and multi-faults exist in Wazhuang oil field, the authors built a 3D reservoir geological model with the help of technical understandings of integrating geology modeling and reservoir numerical simulation and based on the tectonic study, strata contrast, analyses of sedimentary facies and well logging. Citing the model as a static geological model,a refined reservoir numerical simulation was conducted. Based on the historical fitting success, the author carried out a production technology policy limitation study on exploitation formation, well space from the faults and layered oil match, and obtained a rational production policy, providing a rational guide for the production of the oil field.
