【摘要】：结合密井网开发区井断点数据准确、齐全,高密度地震资料品质高、断层反射特征清晰两方面的优势,综合测井、地震数据中的有用信息,阐述了井震结合断层解释技术。该技术包括断层三维识别技术、井震结合断层空间定位、断层假象密井网验证、区分小断层与岩性变化的地震响应特征、井震解释垂向断距对比等内容。通过在长垣油田多个区块的应用,落实了大断层的空间位置,对大断层下盘的断层假象的认识更清楚,小断层解释更准确,整体上提高了各类断层的解释精度。在井震结合断层精细解释的基础上,通过部署平行于断面的大斜度井挖掘断层附近的剩余油,取得了较好的效果。
[Abstract]:Combined with the advantages of accurate, complete, high density seismic data quality and clear reflection characteristics of fault in dense well pattern development zone, combined with useful information in logging and seismic data, this paper expounds the technology of well shock combined with fault interpretation. This technique includes three dimensional fault recognition technology, well shock combined with fault spatial location, fault image dense well pattern verification, distinguishing seismic response characteristics between small fault and lithologic change, well shock interpretation vertical fault distance correlation and so on. Through the application in many blocks of Changyuan Oilfield, the spatial position of large faults is implemented, the false image of faults in the footwall of large faults is understood more clearly, the interpretation of small faults is more accurate, and the interpretation accuracy of all kinds of faults is improved as a whole. On the basis of well shock combined with fine interpretation of faults, the remaining oil near the fault is excavated by deploying large deviated wells parallel to the cross section, and good results are obtained.
