In Central Asia five countries of CIS,there occur over 100 uranium deposits of different types:sandstone,alkaline metasomatic rock,uranium and coal-bearing rock,fish fossil-bearing mudstone and carbonate rock,of which uranium reserver is about 30％ global uranium industrial reserves.

中亚独联体五国：哈萨克斯坦、乌兹别克斯坦、吉尔吉斯坦、土库曼斯坦和塔吉克斯坦的中亚大陆地壳构造单元，其中分布着大批砂岩型铀矿床和碱交代岩型、含铀煤岩型、含鱼残骸泥岩型和碳酸盐岩型铀矿床，计百余个。

As pH value varied in the course of diagenesis,reservoirs experienced one to three cementations or dissolution generations.Lots of secondary dissolution pores developed in the late diagenetic stage,because of the acidic mediums in the process of generation and migration of oil and gas. The anhydrites deposited in the dissolved pores resulted in the heterogeneity of secondary pores.

储层在成岩过程中受地层水pH值变化的影响，经历1~3个世代的胶结或溶蚀作用，其中在晚成岩期油气生成和运移过程中形成的酸性成岩环境对早成岩期生成的碳酸盐岩胶结物和储层中的长石矿物溶蚀，因而产生了大量的次生溶孔，但随后在溶孔中沉淀了不等量的硬石膏，导致了次生孔隙的非均质性。

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.
