| 摘 要： | 为了研究镍钒元素分布特点及其与油气藏的关系,统计分析了准噶尔盆地各层（不合地表）岩心、岩屑和原油中镍和钒元素的含量,发现在泥岩的镍、钒含量最大、砂岩的次之、油样和油砂（沥青）的较小,试油结果也有同样的结论;剖面上来说,侏罗系和二叠系（烃源岩层）的镍、钒含量较大,大于别的层至少一个数量级;对单井而言,当试油结果为油水同层或含油水层时,镍钒含量大,纯油层反而小,说明水层对微量元素的贡献是增大的正效应,油层是负效应;单井试油结论为纯水,那么该层的镍钒比值就小于1.最后指出A至G镍钒元素的低值区是油气勘探的有利区.

| Abstract: | To study the relationship between Nickel and Vanadium distribution characteristics with HC accumulation, statistic analy- sis has been conducted on the content of Nickel and Vanadium on the basis of core, core borings and crude oil data from Junggar Basin. The study results showed that the content of Nickel and Vanadium is the largest in mudstones, secondarily in sandstones, and very small in oil samples and oil-bearing sands （bitumen）. In stratigraphy, the content of Nickel and Vanadium is the largest in Jurassic and Permian. Statistic analysis has also been conducted on the planar distribution of Nickel and Vanadium in the target Jurassic. The statistic analyzing results on the content of Nickel and Vanadium showed that the southeast part of Block A is favorable area for HC exploration, with low value of Nickel and Vanadium contents. The south part of Block F is also the favorable area for HC exploration, with low value of Nickel and Vanadium contents. When conducting well production testing in individual well, the content of Nickel and Vanadium is large at oil-water layers or oil bearing water layers, and small in pure oil layers, which indicated that water layers will increase the content of Nickel and Vanadium, and oil layers will decrease the content of Nickel and Vanadium. When conducting well production testing in individual well, the ratio of Nickel and Vanadium is 1 at pure water layers. Finally, it is pointed out that from A to G Blocks, the areas with low content of Nickel and Vanadium are favorable HC exploration areas in Jung- gar Basin. |
