摘要：

针对塔河油田碳酸盐岩缝洞型油藏的特点,探索出适应塔河油田碳酸盐岩缝洞型储层的精细成像技术方法。主要包括统计去噪、地表一致性处理、子波一致性处理、速度分析、三维DMO叠加、串联偏移等成像技术。这些技术的精细组合使用,使奥陶系顶风化面及内幕岩溶特征准确成像,提高了钻井的油气产率,为塔河油田的稳步快速发展提供了技术保障。

Abstract: A fine seismic imaging technology tailored to fit the characteristics of the fractured-vuggy carbonate reservoirs in the Tahe oilfield is developed.It consists of a series of techniques,including noise elimination,sur-face consistency processing,wavelet consistency processing,velocity analysis,3D DMO stacking,cascade migra-tion to image,and etc.It has been proven that a delicate combination of these techniques can yield fine images of the top erosional surface and inner karst of the Ordovician,thus improving oil well yield and providing technical support for a steady and fast development of the Tahe oilfield.

Key words: erosional surface, beaded anomaly, 3D DMO, velocity analysis, cascade migration, carbonate rock, Tahe oilfield
