| 摘 要： | 针对大庆长垣应用油藏地球物理技术开展精细油藏描述的难点问题，系统阐述了井震联合小尺度构造解释的方法和储层预测的研究。(1)开展分级分层次构造解释，建立了小尺度地质体精细构造解释；(2)在低级序小断层识别和组合方面，采用井指导和验证地震断层解释，同时结合相干体、倾角定位、三维可视化等技术进行综合研究；(3)微幅度构造研究采用井点分层数据小网格成图为主，辅以手动识别、趋势面法、相干体等手段进行逐一落实。储层应用实践证明，地震属性技术预测储层普适性较差，对“泥包砂”型的砂体预测是有效的。地震重构反演技术预测储层精度较高，不仅较好地反映砂体接触关系，而且预测了砂体横向边界。采用“井点定相、切片组形”方法，利用测井曲线形态差异和高程差等特征，辅助以反演切片来研究河道垂向演化，最终实现多期河道的划分。

| Abstract: | According to the problem of using reservoir geophysical techniques in potential tapping of residual oil becoming hard in Daqing Changyuan,this article systematically expounds well-to-seismic integration structure research and reservoir prediction.Well-to-seismic integration technique makes micro structure interpretation successful in the practice.(1) Hierarchical structural interpretation is carried out,and structural interpretation of small-scale geologic body is established;(2) On low grade faults identification and combination,well log data are used to guide and to verify seismic faults interpretation,combined with the techniques concluding coherent body inclination positioning,3D visualization,etc;(3) On micro-amplitude structure,well point hierarchical data grid mapping are adopted,assisted by hand recognition,trend surface analysis,coherence cube,to implement the structure one by one.The practice of reservoir application proves that the popularity of using seismic attribute to predict reservoir is very limited,but in predicting 'bit balling sand' sand body,it is successful.The accuracy of seismic reconstruction inversion technique in reservoir prediction proves to be very high.It not only reflects sand bodies contact relationship well,but also predicts sand body horizontal boundary.By the method of 'well determine facies,slice assemble shape',using the characteristics of well log shape difference and height difference etc,assisted by inversion slice in river course vertical evolution research,finally multi-period river classification is achieved. |
