Four-mode coherent-entangled state and its application

A new kind of four-mode continuous variable coherent-entangled state is proposed in the Fock space by using the technique of integration within an ordered product,which exhibits both the properties of a coherent state and an entangled state,and spans a complete and orthonormal representation.The conjugate state of the four-mode continuous variable coherent-entangled state is derived by using the Fourier transformation.Moreover,a simple experimental protocol of generating a four-mode continuous variable coherent-entangled state is proposed by using beam splitters.As applications of this four-mode continuous variable coherent-entangled state,a four-mode entangled state and a four-mode squeezing-Fresnel operator are constructed.     

Wigner function for the generalized excited pair coherent state

This paper introduces the generalized excited pair coherent state （GEPCS）. Using the entangled state 〈η〉 representation of Wigner operator, it obtains the Wigner function for the GEPCS. In the ρ-γ phase space, the variations of the Wigner function distributions with the parameters q, α, k and l are discussed. The tomogram of the GEPCS is calculated with the help of the Radon transform between the Wigner operator and the projection operator of the entangled state ｜η1, η2, τ1, τ2｜. The entangled states ｜η〉 and ｜η1, η2, τ1, τ2〉 provide two good representative space for studying the Wigner functions and tomograms of various two-mode correlated quantum states.

利用|x〉导出λ■+μ■的本征矢

利用坐标本征矢|x〉在Fock空间的展开式,导出了算符λ■+μ■在Fock空间的本征矢|ψ〉,并证明了其正交完备性.结果表明,得到的|ψ〉既是完备的,又是正交的,完全可以作为一个表象使用.当λ和μ分别取1和0时,|ψ〉约化为坐标本征态|x〉,而当λ和μ分别取0和1时,|ψ〉约化为动量本征态|p〉.因此,|ψ〉所构成的表象是介于坐标表象和动量表象之间的中介表象.

含油饱和度恢复法定量评价砾岩油藏水淹层

由于储层非均质性严重,砾岩油藏具有岩性物性背景复杂以及油层电阻率变化幅度大等特点,其水淹层的定量评价已经成为油田二次调整开发的重点和难点。基于测井、取芯、测试等分析资料,应用油气运聚成藏理论,在储层品质因子研究的基础上,建立了砾岩油藏原始含油饱和度的计算模型。定义原始含油饱和度和目前含油饱和度的差值与原始含油饱和度的比值为储层的采出指数,表征注水开发以后到目前油藏状态下储层动态水淹的特征参数,与传统的产水率和含油饱和度两个水淹特征参数相比,其优势在于考虑了油层动态水淹的过程,消除了砾岩油藏本身因为电阻率变化幅度大且单一利用目前含油饱和度定量评价水淹层的缺点。将该法应用于克拉玛依油田砾岩油藏水淹层的评价中,对比研究了含油饱和度、产水率和采出指数3个参数对砾岩油藏的水淹敏感性。结果表明：采出指数敏感性最高,识别准确率达到89.58%,提高了砾岩油藏水淹层的识别精度,为克拉玛依油田井网调整和开发方案的设计提供了技术支持。     

鄂尔多斯盆地超低渗透储层形成的宏观地质因素分析

 鄂尔多斯盆地由于特殊的构造特征和沉积背景形成了大面积的低渗透储层。根据扫描电镜、铸体薄片、岩心观察、物性分析、岩心分析化验等资料总结分析了鄂尔多斯盆地X油田长6₃超低渗透储层的微观特征,分析得出超低渗透储层主要受沉积和成岩作用影响。研究区岩性偏细,以细砂岩为主;填隙物含量高;储集空间主要以剩余原生粒间孔与溶蚀孔隙为主。从物性角度来看,储层主要属于低孔、特低孔、超低孔-超低渗储层,以小孔细喉型为主。储层微观特征主要受宏观地质因素控制。沉积作用控制着储层的岩性和填隙物的含量,决定着原生孔隙的大小。成岩作用的压实作用与胶结作用破坏了原生孔隙,溶蚀作用提供了大比例的次生孔隙,改善了研究区的储集空间。     

New two-mode intermediate momentum-coordinate representation with quantum entanglement and its application

We construct four linear composite operators for a two-particle system and give common eigenvectors of those operators. The technique of integration within an ordered product (IWOP) of operators is employed to prove that those common eigenvectors are complete and orthonormal. Therefore, a new two-mode intermediate momentum-coordinate representation which involves quantum entanglement for a two-particle system is proposed and applied to some two-body dynamic problems. Moreover, the pure-state density matrix | ξ ₁ ,ξ ₂ >_C,DC,D< ξ ₁ ,ξ ₂ | is a Radon transform of Wigner operator.
