【摘要】 针对大庆长垣东部葡萄花油层厚度薄、相带窄、受分辨率的限制,约束稀疏脉冲反演处理不能有效地对储层进行识别的地质特点,以宋芳屯油田芳231区块为研究对象,根据研究区域内井网密度差异大的特点,采用模拟技术序贯高斯协模拟,更多地考虑已知数据的空间相关性,将地质统计模拟引入到储层预测研究中,并充分利用地震数据体的横向分辨率,约束地层的空间展布。应用三维随机反演方法,进一步提高储层预测的分辨率,更好地识别砂体。更多还原

【Abstract】 The Putaohua oil layer in the east Daqing is very thin,constrained inversion processing cannot effectively identify the reservoir because of resolution limitation.The 231 block in Songfangtun oil field with large difference of well density was studied.Geological statistics simulation has been introduced into reservoir based on spatial correlations of known data and sequential Gauss modeling. The horizontal resolution of seismic data volume was used to constrict spatial distribution.The 3—D random inversion has been used to improve the resolution of reservoir characterization.更多还原
