制约高邮凹陷复杂断裂带许庄地区勘探的主要原因是构造破碎、地震资料品质差、构造落实难度大。为此依托真武-联盟庄高精度三维资料,本文从研究区域断裂系统入手,通过合成地震记录进行准确层位标定,利用随机剖面法和井震结合法等技术提高层位追踪解释精度,采用相干体技术、切片技术及数据融合技术等手段加强断层识别力度特别是控圈小断层的识别,并有效指导断层组合方式,最后采用变速成图技术进行时深转换。通过采用上述一套精细地震解释技术,提高了许庄地区构造的落实程度,取得了比较好的勘探效果。
The main reason that restricts the exploration in the Xuzhuang area of the complex fracture zone in the Gaoyou Depression is that the structure is fractured, the seismic data quality is poor, and the structural implementation is difficult. Therefore, based on the high-accuracy 3D data of Zhenwu-Union Village, this paper starts with the study of the regional fault system, the accurate horizon calibration through synthetic seismogram, the technique of stochastic cross-section and well-seismic combination to improve the accuracy of horizon tracking and interpretation, Body technology, slicing technology and data fusion techniques to strengthen the fault recognition efforts, especially the identification of small faults in the control loop, and effectively guide the fault combination method. Finally, the technology of variable speed mapping is used for time-depth conversion. Through the use of the above set of fine seismic interpretation techniques, the implementation of the Xuzhuang area structure has been enhanced and a good exploration result has been achieved.
