在利用岩心资料划分流动单元的基础上,用岩心刻度测井资料建立了流动单元储层参数评价模型。利用该模型对储层空间流动单元进行划分和综合研究,结果表明,根据流动单元的渗流特征、储层质量、渗流能力及沉积微相等方面的特征,可将流动单元划分为7种类型。流动单元空间分布主要受沉积微相控制,剩余油主要分布于流动能力中等的Ⅴ—Ⅶ类流动单元中。在开发过程中,由于不同流动单元的变化程度不同,使不同流动单元之间的渗流能力相差较大。该研究结果揭示了在注水开发过程中高孔、高渗疏松砂岩储层不同流动单元的变化特征以及流动单元对微裂缝的形成、剩余油富集规律的控制作用,为高含水时期油田的控水稳油方案的制定提供了依据。

利用地震、测井、录井等资料,对辽河盆地东部凹陷北段古近系进行了层序地层学分析,并对每个层序的发育特征、生储盖组合及油气藏类型进行了详细研究。结果表明,该区古近系可划分为SⅠ,SⅡ,SⅢ和SⅣ4.层序,分别对应于房身泡组、沙三段、沙一段沙二段和东营组。SⅡ层序水进体系域最大湖泛期沉积的半深湖深湖相暗色泥岩是研究区的主力烃源岩系;SⅢ层序水进体系域最大湖泛面附近的浅湖相泥岩是最重要的区域盖层。良好的生储盖配置使SⅡ层序、SⅢ层序水进体系域的扇三角洲、滩坝及浊积扇砂体成为本区最佳勘探目标层。SⅡ层序高位体系域生储条件配置好,又有SⅢ层序区域盖层的整体封盖,油气聚集受局部盖层直接控制,可成为较有利的勘探目的层。SⅡ层序、SⅢ层序低位体系域的冲积扇、辫状河砂体体积规模较小,难以形成大油气藏。

In this paper, the dual code of the binary cyclic code of length 2 n-1 with three zeros α, α t 1 and α t 2 is proven to have five nonzero Hamming weights in the case that n 4.is even and t1 = 2 n/2 + 1, t2 = 2 n-1-2 n/2+1 + 1 or 2 n/2 + 3. where α is a primitive element of the finite field F 2 n . The dual code is a divisible code of level n/2+1, and its weight distribution is also completely determined. When n = 4. the dual code satisfies Ward's bound.
