摘要
采用基于地震波形分类的地震相分析与沉积相解释、波阻抗约束稀疏脉冲反演、地震多属性储层预测及油气检测等针对岩性油气藏的储层地震预测技术,从塔中地区卡塔克1区块泥盆系东河砂岩储层的生储盖组合条件及相关的地震地质特点出发,利用卡1三维地震资料开展目的层系的目标精细解释,结合已有的钻探、测井和测试等资料,揭示了东河砂岩储层砂体的空间展布特征,圈定出砂岩发育带,并对有利储层段的潜在含油气性进行了综合预测和评价.
Taking account of the source-reservoir-seal assemblage of Devonian＇s Donghe sandstone formation and it＇s seismic-geologic characteristics, adopted the seismic interpretive techniques of reservoir prediction for lithological oil/gas reservoir, including the seismic facies analysis based on waveform classification and sedimentary faices interpretation, the wave impedance constraint sparse impulse inversion, the seismic multi-attributes reservoir prediction and oil-gas detection, the fine interpretation of reservoir target utilizing 3-D seismic data from Katake＇s 1 block in Central Tarim basin has been pursued with reference to existing drilling, logging and testing data. The distribution features and development sections of Donghe sands have been revealed and delimited. Moreover, the potential beneficial zones bearing oil/gas in the development sections have been carried on the integrated prediction and evaluation.
