The reservoir rock types in the region of interest are grain limestone, algal limestone, cryptite, siltstone, muddy limestone and mudstone. The thesis identified as a result of changes in the deposition causing the heterogeneity in plane, and then the geological oil reserves have been calculated in accordance with the areal heterogeneity.3、Based on the data of core analysis, bore logging, array induction imaging log and FMI, porosity and permeability model were built using regression analysis. Through testing 45 rock samples, a, b, m, n value were obtained and used to calculate single-layer oil saturation value using the Archie formula. According to the theory of laterolog and inductolog, resistivity ratio and cross plot were used to identification effective thickness. Effective thickness was identified delicately in 103 wells. Based on the over work, active porosity and oil saturation was calculated accurately.4、According to observation of 100 pieces of the thin slices, cast thin slices and 383m core in three wells, the chief diagenesis in this area were compaction, cementation, denudation and cataclasis. Cementation and denudation were universally influenced active porosity this area. The intergranular pores, residual pores and secondary pores were formed in thin carbonated reservoir of lacustrine facies.5、The influence of reservoir heterogeneity to reservoir calculation was analyzed systematically using actual data. And the conclusions were as follows:①The principal reason leading to oil distribution unequal is interior structural feature of reservoir in structural hydrocarbon reservoir.

确定了由于沉积微相的变化而导致的平面非均质性，进而在平面上按照平面非均质单元计算了石油地质储量。3、利用岩心分析、常规测井曲线与阵列感应、成像测井资料相结合，分岩性利用回归分析方法建立了储层孔隙度、渗透率模型；通过对45块岩样进行岩电试验，获取了a、b、m、n值，利用阿尔奇公式计算了各单层含油饱和度值；根据侧向电阻率和感应电阻率串并联特性，利用电阻率比值法与常规交会图法相结合重建了有效厚度图版，对全区103口井目的层段进行了有效厚度精细划分，通过以上工作，准确求取了储量计算单元内有效厚度参数、有效孔隙度参数以及含油饱和度参数。4、通过对研究区3口井383m岩心观察，100余块薄片、铸体薄片镜下鉴定得出：油泉子油田上、下油砂山组储层主要成岩作用是压实作用、胶结作用、溶蚀作用和破裂作用，其中溶蚀作用、胶结作用最普遍，这两种作用对有效孔隙度影响最大，以上成岩作用形成了原生粒间孔、粒间残余孔和次生孔隙(如粒间溶孔、粒内溶孔、铸模孔、晶间孔等)为主的薄层湖相碳酸盐岩储层。5、利用实际资料，系统分析了油藏非均质对储量计算的影响，认为：①对于构造油气藏而言，油气藏构造及断裂特征是造成油气分布不均的首要原因，储集条件相同的条件下，构造高部位有利于储存油气，油气在垂向的重力分异体现了油气藏内部构造的不均一特征。
