摘要
本文从对岩心中裂缝的观察入手，经过对岩心节理走向的古地磁定位分析，总结了松辽盆地头台油田扶余油层储层裂缝的空间展布特征。同时，运用纵波波速的比值———“龟裂系数”方法对扶余油层储层的裂缝发育频率进行了分析、计算。结论表明，头台油田储层的裂缝极为发育，裂缝参数特征必然影响油田生产。
Based on observation of fracture in cores and through archaeomagnetism positioning analysis on joint strike of cores, this paper concludes out the spatial distribution characteristics of fractures in Fuyu oil pay zone of Toutai oil field in Songliao basin. In the meantime, fracture developing frequency of Fuyu oil pay zone is analyzed and calculated by using ratio of vertical wave velocity—“crocodile factor”method. Its conclusion shows that fractures in Toutai oil field is very well developed, so fracture characteristics will inevitably affect oil field production.
