昆2井优快钻井及油气层保护技术

昆2井是一口位于柴北缘西段的昆特依凹陷潜伏Ⅰ号圈闭上的风险探井,设计井深为5950m。针对柴北缘深探井存在的主要技术难题,制定了昆2井的技术对策。通过对钻井设备的优选、井身结构的优化、钻头及钻具组合的优选、钻井参数及钻井液性能的优化、油气层保护技术的研究与应用,形成了一套适合于柴北缘的优快钻井技术,使昆2井的完钻井深达到5950m。与邻区的深探井平均水平相比,在井深增加888m、大尺寸井眼段更长的前提下,昆2井的钻井、完井周期分别缩短了98.75d、124.2d,钻机月速度增加了317m/台,平均机械钻速增加了0.82m/h。根据“理想充填新理论”,确定了保护油气层的最优复配暂堵方案,利用该方案所配制的钻井液其渗透率恢复值达到了87.5%以上,流变性能良好,滤失量低,对改善泥饼质量、增强井壁稳定性有明显的效果。     

小红楼

小红楼建于1921年，是一座三层的法式小洋楼。三十年代，它被英国百代唱片公司收购，抗日战争期间，一度被日本人占有，解放后，它成为中国唱片公司的所在地，伟大的中国国歌就诞生在这里。     

Synthesis,characterization, and redox and electrochromic behaviors of poly(3-n-octyloxythiophene)

Poly(3-n-octyloxythiophene), a conjugated polymer, which possessed solubility in common organic solvents, was synthesized by electrochemical polymerization in the presence of lithium perchlorate as the supporting electrolyte and sodium dodecyl sulfate as the surfactant in an aqueous medium. Characterizations of the intermediate, monomer, and polymer were performed by NMR spectroscopy, Fourier transform infrared spectroscopy, ultraviolet–visible spectroscopy, and gel permeation chromatography. The process of electrochemical polymerization and the electrochemical redox behaviors were investigated by cyclic voltammetry and the potentiostatic method. A poly(3-n-octyloxythiophene) film that was deposited on a platinum electrode was found to exhibit electrochromic behaviors, and it switched electrochemically between blue–green oxidized and dark red reduced states. © 2008 Wiley Periodicals, Inc.

Challenges Facing Chinese Refineries and Demand Forecast for 2015

After several decades of development the processing capacity of Chinese refineries has reached 276 million tons per year,ranking the fourth in the world. The refining industry has made great contribution to the growth of national economy in China.With changing times, especially after China's accession to the WTO, significant changes have occurred in economy, politics and petroleum market both at home and abroad. The survival and growth of Chinese refineries has faced new challenges.

Optically tuned superconductive-dielectric resonators with whispering-gallery modes

An analytical method is presented for calculating the resonant frequency andQ-factor of a superconducting dielectric disk resonator operating in millimeter-wave regime with whispering-gallery mode. Resonant frequency shift due to the optical generation of quasi-particles in superconducting film is investigated as a function of photon flux. An optically tunable resonant frequency of about 500 MHz is estimated, and good agreement is found between numerical results and experimental ones.

吸附法脱除乙烯中少量氧气的吸附剂研究

采用重量法在电子天平上研究了Ｃ２Ｈ４和Ｏ２单组份在５Ａ、１３Ｘ、丝光沸石和碳分子筛等不同吸附剂上的吸附平衡性质和扩散动力学性质。结果表明，在沸石类吸附剂上，Ｃ２Ｈ４的平衡吸附量远大于Ｏ２的平衡吸附量，Ｃ２Ｈ４的吸附扩散速率也大于Ｏ２的扩散速率；在碳分子筛吸附剂上Ｃ２Ｈ４的平衡吸附量大于Ｏ２的平衡吸附量，但Ｏ２的吸附扩散速率远大于Ｃ２Ｈ４的扩散速率，其扩散系数是Ｃ２Ｈ４的２３９倍。单柱评价结果表明，Ｃ２Ｈ４－Ｏ２混合组份通过该碳分子筛吸附剂时，Ｏ２的破点时间长，Ｃ２Ｈ４的纯度可达１００％。加压有利于选择吸附Ｏ２，而且加压吸附、常压脱附再生性能好。该碳分子筛是脱除高浓度乙烯中少量氧气的理想吸附剂。     

离子液体催化C_5馏分中二烯烃的聚合反应

合成了多种基于1-丁基-3-甲基咪唑阳离子的离子液体,并作为裂解C5馏分中混合二烯烃聚合反应的介质。考察了离子液体种类、反应温度、反应时间和添加Lew is酸对混合二烯烃聚合反应的影响。实验结果表明,以硝酸根为阴离子的离子液体对混合二烯烃的聚合反应具有一定的阻聚作用;以六氟磷酸根为阴离子的离子液体能明显促进混合二烯烃的聚合反应,提高二聚物的含量;添加Lew is酸(质量分数为1%的ZnCl2)的离子液体对混合二烯烃的聚合反应具有更明显的促进作用,其效果仅次于酸性氯铝酸类离子液体,反应温度以30℃以下为宜,温度过高将促使二聚物进一步聚合,形成三聚物乃至多聚物,降低二聚物的含量。
