摘　　要：复杂断块油藏描述要解决的关键问题是断层识别、平面组合及断块的划分。利用地层分层数据和地震剖面常规解释方法,断层组合方案往往存在多解性,使断块的划分与地下实际情况相差甚远,造成井网不合理、注采系统不完善。相干分析技术能够使断层的平面走向和切割关系形象的显示出来,使精细断层描述更快更准。During the description of complicated fault-block oil reservoirs, the key tasks include the recognition and horizontal assemblage of faults and the classification of blocks. Fault combination program always gives multiple solutions using individual -layer data of formation and common interpretation method of seismic profile. It makes the division of fault blocks is far different from the actual underground situation, and results in unreasonable well pattern and unperfect injection-production system. Then development effect of the oilfield will be influenced. Coherent analysis technique can vividly reflect plane trend and crosscutting relationship of faults so that the fine fault can be described rapidly and accurately.
