摘　　要：时移地震是剩余油挖潜最直接有效的技术手段,中国大多数老油田包括南海东部惠州A油田并没有实施时移地震采集。为了弄清已经进入特高含水期、高采出程度开发后期惠州A油田油水分布及运动规律,在已经正交采集一次三维资料和二次三维资料的条件下,以数学运算方法对一次三维和二次三维资料实施双方位非重复性时移地震处理,达到了减少时移地震采集成本投入和预测剩余油分布的目的。经过钻井证实,剩余油预测结果与钻探结果吻合,该方法可供海上油田推广借鉴。Time lapse seismic acquisition is the most direct and effective technical means for tapping remaining oil potential.Most of China’s old oil fields,including Huizhou A oilfield in the eastern South China Sea,have not implemented time lapse seismic acquisition.In order to clarify the distribution and movement patterns of oil and water in Huizhou A Oilfield,which has entered the stage of ultra-high water cut and high recovery,under the conditions of orthogonal collection of old 3D data and new 2D data,a mathematical operation method was used to perform dual directional non repetitive time-lapse seismic processing on the primary and secondary 3D data,achieving the goal of reducing the cost of time-lapse seismic acquisition and predicting the distribution of remaining oil.After drilling verification,the remaining oil prediction results are consistent with the drilling results,and this method can be used as a reference for the promotion of offshore oil fields.
