摘　　要：裂缝性储层的评价一直是石油勘探开发的难点。海拉尔盆地贝尔凹陷布达特群储层为古潜山油藏,岩性较复杂,属双孔隙介质储层,利用常规测并资料评价储层难度较大。本文通过对海拉尔地区布达特层地层研究,总结了利用常规测井资料识别变质岩储层裂缝的方法,为古潜山油藏双孔隙介质储层测井评价提供了新的手段,对其它裂缝油气藏的测井评价具有指导意义。Evaluation of fractured reservoirs has always been a problem in oil exploration and development.It is difficult to evaluate the reservoirs of Budate group,Beier depression in Hailaer basin with conventional log data because they are reservoirs in buried hill which lithologies are complex,belonging to two porous media reservoirs.Through study on the formation of Budate group in Hailaer area,a method for identifica- tion of fractures in a metamorphic rock reservoir with conventional log data is summarized in the paper.It has provided a new way to evalu- ate the two-porous-media reservoir in buried hill.It is of significance in well logging evaluation of other fractured hydrocarbon reservoir.
