摘　　要：根据勘探开发工作需要,对俞垛—华庄区带主要目的层阜三段进行构造精细解释和圈闭评价,以期通过研究该区块断裂系统特征及构造特征来落实有利圈闭。本次研究充分利用了高精度三维地震资料,结合全区地质统层的结果,运用Landmark人机联作,对阜三段地层进行井—震标定,并且运用工区内其他井的信息进行层位追踪,利用空间变速成图技术绘制目的层段构造图。同时,在精细构造解释的基础上,利用相干技术和时间切片辅助进行断层识别以及解释,落实各断块圈闭,为制定开发方案提供可靠的地质和油藏依据,最终优选出8个可供上钻的有利圈闭。For the needs of exploration and development, the main target layer （Fusan section） in the Yuduo--huazhuang area is interpreted in the fine structure and trap is evaluated, in order to implement favorable traps by studying the fracture system feature and structural characteristic in this region. By combining high precision 3D seisimic data and geologic strata partition, this research uses Landmark Interaction software layer to locate the well seismic calibration of the Fusanduan layer so as to determine the seismic reflection and seismic wave group characteristics of the target layer phase. And also other work is carried out with the help of the information in other wells. Based on the fine structural interpretation, the related technique and time slice are used for fault identification and interpretation. Finally, several fault block traps are studied, which is helpful to provide reliable basis of geology and oil reservoir for development program design, 8 favorable traps for drilling are chosen and explorated.
