摘　　要：崔庄-西园油田是复杂小断块油田，断层多而密集，断块含油面积平均不足0．4km2，构造及油、气、水关系十分复杂。不同的断块区油气富集程度、含油层位及原油性质不同；即便处于同一断块区中，各断块含油特点也不相同，有的断块满块富集油气，有的断块则为空断块，这主要取决于控油断层的封闭程度。因此，查明断层是否封闭是确定断块圈闭中能否富集油气的关键。文中利用地震、地质、测井资料对断层面承受应力、断面及两侧储层排驱压力、断裂带内页岩沾污带空间分布的连续性、断层封闭系数等进行了综合研究。在此基础上，对断层的封闭机理进行了分析。The complex fault-block reservoir in the Cuizhuang-Xiyuan is famous small complex fault block area. Faults are many and closed, the forming of reservoir was controled by the sealing of fault. The paper study the force of fault place bearing, the delivery pressure of fault place and reservoir, the continuity of space distribution of the shale polluting zone and the factor of fault sealing making use of the seismic,geological and log data. The paper study the mechanism of the fault sealing on the basis.
