【摘要】 针对松辽盆地北部中浅层薄层识别难的问题,研究出宽频带特高分辨率地震处理技术。该技术应用于松辽盆地北部肇源南三维地震工区,地震分辨率提高了2~3倍,通过精细的井-震对比确定了扶中油层的顶、底界面,利用沿层地震属性提取、三维可视化等技术对扶中油层进行了储层横向预测。依据预测结果,在优选探井井位、优选试油层位和分析开发井油层连通性等方面进行了探索,初步显示出高分辨率地震在薄互层储层预测及岩性油藏地震识别方面的优越性。更多还原

【Abstract】 The broadband ultrahigh resolution seismic processing technique is studied because it is difficult to i-dentify the medium to low thin beds in north Songliao basin. This technique has been applied to 3D seismic work area in the south part of north Zhaoyuan in Songliao basin, and the seismic resolution increased 2-3 times. Based on fine well-seismic comparison, the top and bottom interfaces of Fuzhong oil layer are determined. With the application of lateral seismic attribution extraction, 3D visual technique and other techniques, the reservoir cross range of Fuzhong oil layer is forecast. According to the forecast results, work has been done for exploration well location optimization, well testing horizon optimization and analysis of oil layer connectivity in development wells. The advantage of high resolution seismic for thin alternate layer identification and lithologic reservoir seismic identification is appeared preliminarily.更多还原
