孤东垦东地区储层精细构造解释及构造特征分析

Structural Interpretation and Structural Characteristics of Target Layers in Gudong and Kendong Areas

在孤东垦东地区利用三维地震资料与测井资料结合,实现了地震解释剖面上层位准确标定,并在此基础上开展了构造精细解释,对研究区内断裂的构造特征、演化特征进行了深入研究,针对隐蔽小断层、低幅度构造采用多种地震综合解释技术,完成了沙一段底界、馆陶组下段底界、馆陶组上段底界及明化镇组底界约1200km2三维地震资料精细解释工作,编制了高精度构造图,进一步落实了区内的断裂空间展布特征和构造形态,指出了有利圈闭,为下步井位部署提供了有利依据。

In Gudong and Kendong areas, 3D seismic data is integrated with well logging data to accurately calibrate the horizon on seismic profile, on the basis of which precision structural interpretation is implemented. The pattern of fracture assemblage and structural characteristics are studied deeply in the work area. Various seismic interpreting techniques are used for small hidden faults and low amplitude structures. Precision interpretation on 3D seismic data is conducted on approximately 1200 km2 within the working area, and high precision structural diagrams are plotted for 4 main target layers, many new beneficial traps are founded, by which useful basis is provided for further arrangement of well position.
