利用俄罗斯测井系列的测井曲线，在建立孔隙度、渗透率、饱和度、泥质含量等参数的测井解释模型基础上，系统评价了尤罗勃钦油田的碳酸盐岩储层。针对该区碳酸盐岩储层双重孔隙介质的特点，结合试油资料建立了识别储层类型、裂缝性质、泥岩夹层和致密层的测井评价参数，以此为依据把储层分为基岩型、微裂缝型和大裂缝型3大类，指出裂缝型储层发育方向在平面上是NE—SW向和NW—SE向，分别与尤罗勃钦组、多尔戈克金组和库尤姆宾组的白云岩分布和古潜山构造发育方向一致；纵向上裂缝和大裂缝储层发育段厚度一般在距剥蚀面以下0～100 m，与白云岩溶蚀带发育一致。钻井揭示的裂缝型储层发育段控制了该区的油气分布，但其分布极不均匀。

Reservoir in the Yurubcheno oil field of Siberian platform was evaluated after we used the logging curve of Russian logging series to integrate porosity,permeability,saturation,and shale content.We also use the testing oil data to choose the logging parameter for identifying the reservoir type,fissure property,shale intervals and tight layer in the carbonate reservoir with dual porosity.Based on the result above,the reservoir types were classified into matrix,micro-fissure and macro-fracture.The direction of fractured reservoir distribution was along NE-WS and NW-SE,which was consistent with the direction of dolomite distribution in Yurubcheno Formation,Dolgoktinskaya Formation and Kuyumbinskaya Formation as well as the buried structure.Vertically,the distance of fissure and macro-facture was about 0-100m far away from the unconformity,which was in correspondence with distribution of dolomite corrosion.The drilled hole tested that the fractured reservoir constrained the distribution of the oil and gas,but it was heterogeneity and anisotropy in this field.
