摘要/Abstract

摘要： 断层的精细表征对高含水期复杂断块油田剩余油挖潜具有重要意义。利用井-震标志层对比、地震同相轴变异识别与断层叠合模型验证等方法，对渤海湾盆地沾化凹陷新生界复杂断块油田开展了断层精细表征。研究结果表明： ①沾化凹陷复杂断块油藏断层两侧岩层的对接关系复杂，断层组合样式多样，继承性小微断层发育，通过断点定位、断面解释、断层平面组合与空间叠合建模等，实现断层特别是小微断层的精准识别、定位与表征。②研究区小微断层发育的重要特征为地震剖面中同相轴的扭曲、分叉、合并等变异现象，同相轴微扭动、微扭曲、微错断是小微断层断点识别与定位的重要依据。③断层精细表征使研究区断层的断边“盲区”和“模糊区”变为剩余油富集的潜力区，断层两侧外扩可新增地质储量。断层精细表征可优化完善井网布局、增加挖潜开发实效，还可为进一步明确剩余油富集分布规律、调整开发井网和实施精准开发等提供科学依据。

Abstract: The fine characterization of faults is of great significance for the potential exploration of remaining oil in complex fault block oilfields with ultra-high water cut. The fine characterization of faults in Cenozoic complex fault block oilfield in Zhanhua Sag of Bohai Bay Basin was studied through comprehensive analysis of correlation of well-seismic marker layer，identification of seismic event variation and validation of fault overlap model. The results show that：（1）The jointing relationship of rock formation on both sides of complex fault block reservoirs in Zhanhua Sag is complicated，the pattern of fault assemblage is varied and inherited small and micro faults are developed. The multi-technology fault interpretation method based on breakpoint identification，fault section interpretation，fault plane combination verification and fault space modeling have realized the fine identification，positioning and characterization of the faults，especially small and micro faults.（2）In the seismic profile of complex fault block reservoir in Zhanhua Sag，the variation phenomena of the events such as distortion，bifurcation and merging are important characteristics of the development of small and micro faults. The micro-twist， micro-distortion and micro-misalignment of the events are important basis for the fine identification and location of small and micro-faults.（3）The fine fault characterization can transform “blind area” and “fuzzy area” of the fault edge in the study area into potential area of remaining oil enrichment，which realized the expansion of new geological reserves on both sides of the fault. The fine fault characterization can optimize and improve the well pattern，increase the effectiveness of tapping potential and development，and also provided a scientific basis for further defining the remaining oil enrichment and distribution， adjusting the development well pattern and implementing precise development.

Key words: fine fault characterization, fault breakpoint identification, seismic event micro distort, remaining oil tapping, complex fault block oilfield, Cenozoic, Zhanhua Sag, Bohai Bay Basin
