多信息协同的薄储层刻画研究

Research on Thin Reservoir Depiction Based on Multi-information Collaboration

针对某油田沙漠区薄互储层低信噪比、低分辨率、储层变化快、产量递减快、含水上升快、稳产难度大等问题,采用高分辨率处理技术,获得高精度的地震成像结果。在该基础上,提出采用多信息,按砂体-单砂体-油砂体渐进式的思路刻画储层分布。研究表明,该思路和方法提高了薄储层刻画的可靠性和精度。

In consideration of the problems of low signal-to-noise ratio,low resolution of thin interbedings,rapid reservoir changes,fast production declines,quick increase of water cut,difficult for stabilized production in an oilfield of desert area.To obtain high precise seismic imaging result,the technology of relatively preserving reservoir processing data based on VSP-driven seismic data processing was applied.On the basis stated above,the multi-information according to progressive thought,namely the sand body-the single sand body-the oil sand body is used to characterize the reservoir distribution.The study shows that the research thought and method have greatly improved the reliability and precision of the thin interbeding characterization.
