摘　　要：受断层发育、地表条件等因素影响,复杂断块油藏地震资料普遍较差,断块的控构断层描述通常难以实现一次精确定位。利用动静态矛盾识别发现断层位置不准确迹象,利用井震结合等方法精确描述定位断层位置,提高复杂断块主控断层定位精度。多个老油田主控断层实现不同程度外推,外推部分形成"屋脊式"剩余油分布,为老油田滚动挖潜提供了新的空间。Affected by factors such as fault development,drilling data and some surface conditions,the seismic data of complex fault-block reservoirs are generally poor,and it is usually difficult to achieve precise positioning of the structure-controlling fault description of the fault block.To solve this problem,firstly,the inaccurate indication of fault location is identified according to the contradiction of static geological feature and dynamic production performance;secondly,the fault locations are described and located accurately by the combination of seismic and logging data and some other methods,to improve the positioning accuracy of main control faults in complex fault-blocks.The main control faults in many old oilfields have been extrapolated to different degrees,and the extrapolated part forms a"roof-like"remaining oil distribution,which provides new space for the rolling potential of old oilfields.
