摘　　要：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, 仅用常规测井资料对储层评价难度很大。为此, 将常规测井资料和成像测井资料相结合, 利用先进的孔隙频谱分析 (PoroSpect) 等技术对储层次生孔隙度的发育给出定量描述, 实现了对储层有效孔隙度的定量计算, 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。Budate Group Reservoir in Beier Depression of Hailarer Basin is buried hill oil reservoir,whose lithology is more complex and belongs to dual-porosity reservoir. It is difficult to use conventional logging data to evaluate the reservoir.Therefore,conventional well logging data,combine imaging logging data, with advanced PoroSpect analysis technique,etc.are used to evaluate the development of the secondary porosity in the reservoir quantitatively,realizing quantitatively reservoir effective porosity calculation.It provides new measures for evaluating dual-porosity reservoir logging in buried hill reservoirs,and has a guiding effect for well logging evaluation in other fractural oil and gas reservoirs.
