利用俄罗斯测井系列的测井曲线,系统评价了尤罗勃钦油田的碳酸盐岩储层.在对岩心分析和岩性、电性、物性和含油性特征研究的基础上,充分分析了该油田储层测井响应,针对该区碳酸盐岩储层双重孔隙介质的特点,建立了识别储层类型、裂缝性质等测井评价参数.据此把储层分为基岩型、微裂缝型和大裂缝型3大类.裂缝型储层发育方向在平面上是北东-南西向和北西-南东向,分别与尤罗勃钦组、多尔戈克金组、库尤姆宾组中白云岩分布和古潜山构造高部位方向一致;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左右,与白云岩溶蚀带发育一致.裂缝和大裂缝型储层发育段控制了油气井分布,但裂缝型储层分布仍极不均匀.油气分布主要受储层岩性和其在古潜山的构造位置控制:尤罗勃钦组岩性较单一并处在古潜山构造高部位,油井产量高;多尔戈克金组发育泥岩、泥质白云岩和白云岩互层,虽构造部位较高,但有的井出油,有的井出水,产油量也不高;库尤姆宾组虽岩性单一但构造部位不佳,油气产量也较低.

The carbonate reservoir evaluation based on well logging data of Russian logging series is done in Yurubcheno oil field in Siberian platform. On the basis of the conversional log characteristic analysis, evaluation parameters from the logging data are given for identification of the reservoir types, fractures, shale intervals of the formation and tight reservoirs in the carbonate reservoir with dual porosity. The reservoirs are classified into matrix type, micro fracture type and macro fracture type. The preferential directions of fractured reservoir distribution are NE-SW and NW-SE which are consistent with the distribution of carbonate and the structural high of the buried hill. It generally locates 0-100 m under unconformity which corresponds to the distribution direction of the dolomite corrosion zone, which controls the distribution of the high production wells. But the distribution of the fractured reservoir is heterogeneous and anisotropic in this field. Factors controlling the distribution of oil and gas in this field are the lithology of the reservoir and its structural location in the buried hill. The reservoir in Yurubcheno Formation, which is pure dolomite and has good location in the structure, has high oil and gas yield. There is poor oil and gas production in the reservoirs in Dolgoktinskaya Formation, where the lithology is not pure dolomite, and the Kuyumbinskaya Formation which located at a lower structu-ral location.
