福建省古生代至中生代大地构造演化的格架

松溪—长汀断裂带和福州—永定断裂带是控制福建古生代及以后大地构造演化的两条北东东向的断裂带。地质地球化学资料表明,前者是加里东期的地体碰撞带,沿线分布了构造混杂岩、变质超基性岩体、具有角闪岩相和中压矿物的变质岩以及同碰撞型花岗岩体,以后又发育为A型俯冲带;后者是发育于加里东构造层之上的海西期张裂带,在形成海西期的福州—永定海峡的同时,产生了石炭纪海底双模式火山岩及层控铁矿,印支期的碰撞活动使海峡封闭并发育A型俯冲作用。由此,北东东向的松溪—长汀断裂带和福州—永定断裂带可以将福建划分为三个古生代的构造地层地体:闽北地体、闽中地体和闽东南地体。通过对福建省古生代地体构造分析、古地磁测量及古地理重建,展现在我们眼前是:华南(其中包括福建)在古生代中期从冈瓦纳大陆分离出来后,横渡特提斯海,在古生代末至中生代初到达劳亚大陆,与中朝板块碰撞引起了福建地体间强烈的造山运动。     

冕流与日冕物质抛射的关系

本文研究了卡林顿自转周１５９１ － １５９２ 中冕流偏振亮度的变化。冕流带偏振亮度的分布是不均匀的,不均匀度为１０ ％ － ５０ ％ 。无日冕物质抛射影响存在时,沿冕流带冕流的分布可持续稳定存在近两个太阳自转周。当一个日冕物质抛射伴随冕流产生时,冕流的经向角大小若大于２７°,可导致冕流尖角区顶部上升速度大于２ｋｍ／ｓ。

A time-domain induced-polarization method for estimating permeability in a shaly sand reservoir

It is known that the time‐domain induced‐polarization decay curve for a shaly sand reservoir depends on the pore structure of the reservoir, and this curve can be used to estimate permeability, which is a determining factor in making production decisions in the petroleum industry. Compared with NMR logging tools, induced polarization has several advantages, such as a deep depth of investigation and a high signal‐to‐noise ratio. The purpose of this paper is to establish an appropriate model using induced polarization to estimate the permeability. The curve can be modelled as a weighted superposition of exponential relaxations. The plot of weight versus the relaxation time constant is defined as the relaxation time spectrum. Induced‐polarization decay‐curve measurements were performed on 123 samples from the Daqing oilfield using a four‐electrode technique. A singular‐value decomposition method was used to transform the induced‐polarization decay data into a spectrum. Different models to estimate the permeability were discussed. The results of the research indicate that the induced‐polarization measurements greatly improve the statistical significance of permeability correlations. Compared with the traditional forms, Aφ^C and AF^C, the forms, AT^Bφ^C and AT^BF^C, have lower error factors, where T, Φ and F are the geometric mean time constant of the induced‐polarization relaxation time spectrum, the porosity and the resistivity formation factor, respectively, and A, B and C are constants. The mean time constant is the decisive parameter in the permeability estimation and it is not completely independent of the resistivity formation factor. The additional use of the porosity and the resistivity formation factor leads to an appreciable improvement. It is concluded that this new model will make it possible to estimate the permeability of a shaly sand reservoir downhole.
