泥岩裂缝储层地震识别的理论和方法

During the exploration of fractured reservoirs, worldwide difficult problems will be encountered: how to locate the fractured zones, how to quantitatively determine the azimuth, density, and distribution of the fractures, and how to compute the permeability and porosity of the fractures. In an endeavor to solve these problems, the fractured shale reservoir in SiKou area of ShengLi oil field was chosen as a study area. A study of seismic predictive theory and methods for solving problems encountered in fractured reservoir exploration are examined herein. Building on widely used current fractured reservoir exploration techniques, new seismic theories and methods focusing on wave propagation principles in anisotropic medium are proposed. Additionally, integrated new seismic data acquisition and processing methods are proposed. Based on research and application of RVA and WA methods from earlier research, a new method of acoustic impedance varying with azimuth (IPVA) creatively is put forth. Lastly combining drilling data, well log data, and geologic data, an integrated seismic predictive method for cracked reservoir bed was formed. A summary of the six parts of research work of this paper is outlined below. In part one, conventional geologic and geophysical prediction methods etc. for cracked reservoir exploration are examined, and the weaknesses of these approaches discussed. In part two, seismic wave propagation principles in cracked reservoirs are studied. The wave equation of seismic velocity and attenuation factor in three kinds of fracture mediums is induced, and the azimuth anisotropy of velocity and attenuation in fracture mediums is determined. In part three, building on the research and application of AVA and WA methods by a former researcher, a new method of acoustic impedance creatively varying with azimuth (IPVA) is introduced. A practical software package utilizing this technique is also introduced. In part four, Base on previously discussed theory, first a large full azimuth 3d seismic data (70km~2) was designed and acquired. Next, the volume was processed with conventional processing sequence. Then AVA, WA, and IPVA processing was applied, and finally the azimuth and density of the fractures were quantitatively determined by an integrated method. Predictions were supported by well data that indicate the approach is highly reliable. in part five, geological conditions contributing to cracked reservoir bed formation are analyzed in the LuoJia area resulting in the discovery that the main fractured zones are related to fault distribution in the basin, that also control the accumulation of the oil and gas, the generation mechanisms and types of fractured shale reservoirs are studied. Lastly, by using full 3D seismic attributes, azimuth and density of cracked reservoir zones are successfully quantitative predicted. Using an integrated approach that incorporates seismic, geologic and well log data, the best two fractured oil prospects in LouJia area are proposed. These results herein represent a break through in seismic technology, integrated seismic predictive theory, and production technology for fractured reservoirs. The approach fills a void that can be applied both inside China, and internationally. Importantly, this technique opens a new exploration play in the ShengLi oil field that while difficult has substantial potential. Properly applied, this approach could play an important role toward stabilizing the oil field' production. In addition, this technique could be extended fracture exploration in other oil fields producing substantial economic reward.

菲在土壤／沉积物上的吸附-解吸过程及滞后现象的研究

实验研究了菲在土壤／沉积物上的吸附一解吸过程。CHL土壤和HFH沉积物中有机质的固相^13C CP MAS NMR谱图很相似，表明样品中有机质的组成差异不大；菲在土壤／沉积物上的吸附过程表现出明显的非线性；线性模型不适合拟合菲的吸附等温线，Freundlich模型和双区位反应模型(DRDM)较好地拟合了菲的吸附等温线，其中DRDM模型还清楚地反映菲在低浓度和高浓度下不同的吸附方式；另外，研究表明菲在土壤／沉积物上的解吸过程中存在明显的滞后现象，这可能和土壤／沉积物有机质的异质性和土壤胶团微小孔隙的存在有关。实验研究了菲在土壤／沉积物上的吸附一解吸过程。CHL土壤和HFH沉积物中有机质的固相^13C CP MAS NMR谱图很相似，表明样品中有机质的组成差异不大；菲在土壤／沉积物上的吸附过程表现出明显的非线性；线性模型不适合拟合菲的吸附等温线，Freundlich模型和双区位反应模型(DRDM)较好地拟合了菲的吸附等温线，其中DRDM模型还清楚地反映菲在低浓度和高浓度下不同的吸附方式；另外，研究表明菲在土壤／沉积物上的解吸过程中存在明显的滞后现象，这可能和土壤／沉积物有机质的异质性和土壤胶团微小孔隙的存在有关。

Synthesis of a terbium fluorescent chelate and its application to time-resolved fluoroimmunoassay

A new nonadentate ligand, N, N, N-1, N-1-[2,6-bis(3'-aminomethyl-1 1'-pyrazolyl)-4-phenylpyridine]tetrakis(acetic acid) (BPTA) for a Tb3+ fluorescent complex was synthesized. The Tb3+ complex is strongly fluorescent, having a large fluorescence quantum yield of 1.00 and very long fluorescence lifetime of 2.681 ms in 0.05 M berate buffer of pH 9.1. Streptavidin (SA) was labeled with SPTA by using its succinimidyl monoester, and the BPTA-Tb3+-labeled SA was used in sandwich-type time-resolved fluoroimmunoassay (TR-FIA) of alpha -fetoprotein (AFP) and carcinoembryonic antigen (CEA) in human sera. The Tb3+-labeled SA was also used in competitive type TR-FIA of bensulfuron- methyl (BSM) in water. The detection limits of these assays are 42 pg/mL for AFP, 70 pg/mL for CEA, and 0.4 ng/mL for BSM. In addition, a new simultaneous measurement method for AFP and CEA in a human serum sample was developed by using 4,4'-bis(1 " ,1 " ,1 " ,2 " ,2 " ,3 " ,3 " -heptafluoro-4 " ,6 " -hexanedion-6 " -yl)chlorosulfo-o-terphenyl ((BHHCT)-Eu3+-labeled anti-AFP antibody, biotinylated anti-CEA antibody, and BPTA-Tb3+-labeled SA. The concentrations of AFP and CEA in 39 human serum samples were determined, and the results were compared with those of the independently determined AFP and CEA by TR-FIA with a single-label method. A good correlation was obtained with the correlation coefficients of 0.991 for AFP and 0.994 for CEA.

Stolzman w Belwederze? Instrumentalizacja antysemityzmu w kampaniach prezydenckich w Polsce po roku 1989

Antysemicki dyskurs wcale nie potrzebuje obecności Żydów jako racji swojego bytu i legitymizacji istnienia. Zwalcza Żydów wyimaginowanych i symbolicznych. Żydów z nadania, a zwłaszcza wszystko to, przeciwko czemu występuje i na różne sposoby stara się z Żydami skojarzyć. Praktyka taka niejednokrotnie dała o sobie znać w toku prezydenckich kampanii wyborczych w Polsce po roku 1989. Efektów płynących z instrumentalizacji antysemityzmu, choć samo zjawisko jest godne wyłącznie pogardy, nie należy jednak przeceniać i nadawać mu nadmiernego znaczenia przy interpretacji decyzji powziętych przez wyborców. Gdyby w istocie miał on stanowić instrument o przemożnym oddziaływaniu, to ironizując Aleksander Kwaśniewski nie zostałby dwukrotnie prezydentem Polski.

Recursive Estimation of Motion and Planar Structure

A specialized formulation of Azarbayejani and Pentland's framework for recursive recovery of motion, structure and focal length from feature correspondences tracked through an image sequence is presented. The specialized formulation addresses the case where all tracked points lie on a plane. This planarity constraint reduces the dimension of the original state vector, and consequently the number of feature points needed to estimate the state. Experiments with synthetic data and real imagery illustrate the system performance. The experiments confirm that the specialized formulation provides improved accuracy, stability to observation noise, and rate of convergence in estimation for the case where the tracked points lie on a plane.

Extending snBench to Support a Video-Based Intrusion Detection and Alerting System with a Centralized Hash Table

In this project we design and implement a centralized hashing table in the snBench sensor network environment. We discuss the feasibility of this approach and compare and contrast with the distributed hashing architecture, with particular discussion regarding the conditions under which a centralized architecture makes sense. There are numerous computational tasks that require persistence of data in a sensor network environment. To help motivate the need for data storage in snBench we demonstrate a practical application of the technology whereby a video camera can monitor a room to detect the presence of a person and send an alert to the appropriate authorities.

Godwin, Fénelon, and the disappearing teacher

The connection between Godwin and Fénelon has traditionally been restricted to the famous and controversial moment in the first edition of Political Justice (1793) in which Godwin presents an example of the interdependence of rationality and ethical action. This paper argues, however, that Fénelon, and particularly his political and educational treatise Telemachus (1699), plays a significant role in a number of Godwin's subsequent fictional works. Employing Telemachus to explore the theories of education presented by Godwin in the various editions of Political Justice and The Enquirer (1797), this paper explores the manner in which Godwin's version of the Enlightenment transcendence of pedagogical power comes up against its limits. Reading this issue in relation to Godwin's argument, in ‘Of Choice in Reading’, that literature remains outside of socio-ethical corruption, three of Godwin's major novels are shown to demonstrate that Telemachus provides the chance for meta-textual moments in which the appeal to reason (the reader's rational capacity or ‘private judgement’) is at once reflected upon and produced. Reading educational theories and problems into Godwin's major fiction in this fashion helps to clarify aspects of the Godwinian (or ‘Jacobin’) novel.
