摘要

文中针对大庆油田特高含水期精细调整挖潜,需要精细精确刻画储层的要求,充分利用大庆长垣油田密井网条件下储层精细描述成果及高密度三维地震资料,建立了处理-解释一体化高保真地震处理、大密度合成记录精细标定及地层切片优选方法;针对不同类型砂体分布特点,给出了利用地层切片采用"砂中找泥"和"泥中找砂"的单一河道识别分析方法,形成了"地震趋势为引导,井点相控"的井震结合储层精细刻画方法;实际应用证明对剩余油的分析认识更具针对性,应用点坝识别成果指导了D区水平井方案设计,取得了较好的钻遇效果。
According to the demand of accurate reservoir description for intense adjustment and potential tapping in ultra-high water cut stage of Daqing Oilfield and directed by fine reservoir characterization and high-density 3D seismic data of Daqing placanticline under the condition of dense well pattern,the methods of the high fidelity seismic processing by the integration of seismic date processing and interpretation,the method of high-density fine synthetic calibration and the method of strata slice optimization have been established.Aiming at distribution of different types of sand bodies,the identification method of single channel with the feature of "looking for shale in sand" and "looking for sand in shale" has been given by using strata slices.The accurate reservoir description method using logging and seismic data and "directed by seismic attribution and controlled by single well facies" has been formed.The results show that the methods are much more appropriate for analyzing remaining oil.Horizontal well scheme design in D area has been guided by the results of identifying point bar,and the effects of drilling sand bodies are good.
