The Fuyang oil-layer in North Songliao Basin is characterized by thin interbedded sands and shales, strong lateral variation, strong reservoir heterogeniety, and so on. The thickness of individual sand layers is generally 3 - 5 m. Identifying the channel sand-bodies of the Fuyang oil layer using seismic techniques is very difficult due to the low seismic resolution. Taking the GTZ area as an example, we discuss the genetic characteristics of the channel sand-bodies and point out the real difficulty in using seismic techniques to predict the channel sand-bodies. Two methods for the identification of channels are presented： frequency spectrum imaging and pre-stack azimuthal anisotropy. Identifying the channel sand-bodies in Fuyu oil-layer using the two seismic methods results in a success rate up to 80% compared with well data.

为解决以往油藏描述工作单孔资料在深度和广度上存在明显局限性的问题,提出了一套井震联合地质建模的方法:首先以地震精细解释的层位数据和断层数据为约束,结合测井资料建立构造模型;然后采用地震反演体的概率面在平面上作为约束,纵向上在测井曲线上分类统计各微相的概率分布曲线,在变差函数分析的基础上,采用序贯指示模拟算法模拟出储层微相的空间展布,建立沉积相模型;最后采用相控技术和地质统计学理论,分析参数区域化变量的特征,建立储层属性模型。在大庆萨尔图油田的B1DD区块进行验证的结果表明,井震资料的联合应用揭示了大量的小断层,使断点组合率提高了15%,大于2 m的砂岩预测符合率达到90%以上,提高了井间断层和砂岩的预测精度,进而提高了地质模型、尤其是井间模型的精度。

利用电阻率和声波测井资料估算得到的地层中有机碳含量进行层序地层学分析,可弥补深水沉积体系旋回性不明显的不足,为层序地层单元划分和对比提供依据。首先用△lgR法计算了松辽盆地Gu57井青山口组的有机碳含量,然后利用计算出来的有机碳含量曲线的旋回性,在青山口组识别出4个三级层序旋回和9个四级层序旋回,并进一步划分出水进域和高位域。结果表明基于△lgR值求取有机碳含量具有较高的精度和分辨能力,能够满足深水沉积层序划分的需要。依据有机碳含量的垂向变化趋势,得出了古龙凹陷青山口组时期相对湖平面的升降过程。

In the context of low carbon,this paper discussed the impact of the carbon cap-and-trade policy on the fresh-keeping decision-making of two-echelon fresh agricultural product supply chains under different dominance,and designed cost-sharing contracts to coordinate the supply chain of fresh agricultural products dominated by suppliers and retailers *** results showed that:dominance has no effect on the fresh-keeping decision and total revenue of fresh agricultural product supply chain,but it affects the internal income distribution,and dominance does not always bring more benefits;the implementation of carbon cap-and-trade reduces the fresh-keeping decision-making of fresh agricultural products supply chain and reduces the free-rider income of followers;the role of higher carbon trading price is twofold,which not only brings about the speculation of leading enterprises,but also promotes the application of low-carbon technologies;consumers’high preference for freshness,low-cost and high-efficiency low-carbon technology are all conducive to improving the fresh-keeping efforts and benefits of the supply chain;cost-sharing contracts can coordinate the supply chain of fresh agricultural products.
