南堡凹陷奥陶系潜山精细构造解释和储层预测综合研究

A comprehensive study of the refined structural interpretation and reservoir prediction in the Ordovician burial hill in the Nanpu Sag

随着冀东油田勘探开发进程的不断深入,在2006年南堡凹陷大连片地震处理的基础上开展微构造、薄互层、精细油藏描述等问题研究的目标攻关处理.依托高分辨率、高保真和高信噪比的新数据体,开展南堡奥陶系潜山的精细构造解释和储层预测研究,结合多种技术进行井震标定分析,确定各地质层位的地震反射特征,并在工区内测井信息的参考下进行横向追踪,落实主力含油层段构造.在构造解释的基础上综合利用相干技术、蚂蚁体追踪技术和地震相分类技术等对南堡奥陶系潜山储层进行预测,评价出可以优先施钻的6个构造圈闭.

The seismic data can not meet requirement of production with the advancing of exploration and development in the Jidong Oilfield.So we do the research dealing with the seismic data of the Nanpu Sag for micro-structures,thin interbeds,and fine reservoir description,based on the processing of the large joint processing data in 2006.The work includes the refined interpretation and reservoir prediction based on the seismic data of high-resolution,high fidelity and high signal to noise ratio.We use many technologies to determine the relation between the seismic data and the well data and analyze the seismic reflection characters of geologic horizons,then we track transversely and get the main structures of oil layers with the help of logging information in the area.Finally we obtain six beneficial structural traps in the Ordovician burial hill after the comprehensive prediction by the coherent technology,ants body tracking technology and seismic phase classing based.on the refined interpretation.
