【摘要】 针对王庄地区郑4潜山裂缝性储层的特点,利用断裂增强滤波处理后的地震资料,提取了反映储层微裂缝的最优几何属性。曲率属性描述了微断裂体系的线状特征,最大曲率的方位角则代表了裂缝的方向,通过最大曲率属性的两个不同量得到裂缝密度和方向,从而刻画出裂缝空间的网状结构及其横向的连续性,成像裂缝性储层的三维的微断裂体系,结合已完钻井的生产资料,明确了该区裂缝的发育特征,为下一步部署井位进行剩余油挖潜,提高采收率提供了有力的科学依据。更多还原

【Abstract】 According to the fractured reservoir characteristics of Zheng4 buried hill reservoir in Wangzhuang area,the optimal geometry which represents the properties of micro-cracks has been extracted from the enhanced filtering seismic data.Curvature attribute describes the linear characteristics of micro fault system;the azimuth of maximum curvature represents the direction of fracture;the density and direction can be acquired by the two different amount of maximum curvature,which depicts the network structure and horizontal continuity of cracks.The characteristics of fracture development area is clear with the research of three-dimensional micro-fracture system imaging,combined with the production data of wells which have been completed,and this is to provide a strong scientific basis for the next deployment of the remaining oil wells to enhance oil recovery.更多还原
