长庆油田苏平1井固井技术研究与应用

苏平l井完井方式运用了技术套管一次上返、悬挂尾管和筛管技术。该井技术套管段井眼大、裸眼段长，加上大斜度、小间隙的尾管段．对水泥浆体系的性能要求较高。总结分析了长庆天然气水平井苏平l井的固井技术问题，介绍了苏平l井的井身结构与地层性质。通过研究．确定采用低失水GSJ水泥浆体系。该体系成功地应用在三次工程建井过程中，解决了长裸眼、大灰量、大斜度、尾管小间隙等固井技术问题。固井质量达到工程要求。     

The Challenge of the Market

Identifying markets for new or improved products for minor crops threatened with extinction is one critical component of any strategy intended to enhance prospects for sustainable production and use. Typically, however, activities linked to the sustainability of these commodities avoid addressing questions associated with assessing their commercial potential. After a brief review of this avoidance syndrome, this article presents a sample of practical, low-cost procedures to help evaluate the market prospects and procedures for crops like quinoa, while citing references to other methodological materials covering similar topics.

加强石油天然气工业的立法，是社会主义市场经济发展与油气勘查开采实践的需要。针对现行油气管理法规在矿种管理体制，相邻采矿权人关系，油气采矿人主体资格，解决采矿权纠纷等未明事项，运用法学理论进行了剖析；阐述了加强油气立法工作的必要性和紧迫性；并有针对性地提立法建议，以期引探讨和有关部门重视。     

在役加氢反应器试验板脆化和氢损伤的测定与研究

充分利用了带主焊缝的役后试板，在国内首次开展回火脆化、氢介质下断裂韧性与疲劳扩展的研究，结果表明，加氢反应器焊缝有明显的脆化表现。同时，核查了反应器开停车升温速度和降温速度规定，以及确定了裂纹允许尺寸的参考数据，为今后安全运行提供了充分的依据。     

中国先进研究堆堵流事故分析

堵流事故是板状燃料研究堆发生概率相对较高的一种事故。本文进行CARR堵流事故分析时,假定额定功率运行下,1盒燃料组件的入口全部堵塞。用Relap5\Scdapsim\Mod3．2程序分析堵流事故时反应性、堆功率、压力、流量和温度等的变化,并分析发生堵流的标准燃料组件对周边燃料组件的影响。结果表明,发生堵流的燃料组件将烧毁,但不向相邻的组件扩展。CARR设计采取的安全措施可以把堵流事故后果控制在可接受范围之内。     

砾岩油藏合理注采压力系统研究--以七中东区八道湾组油藏为例

注采压力系统指的是从注水泵站到采油井井口的各环节的压力配置 ,在这一压力系统中 ,地层压力和油井流动压力是决定整个压力系统的关健 ,也是油藏工程研究的核心。本文利用油藏工程方法对砾岩油藏高含水期油井和注水井的地层压力、流动压力等注采压力系统进行了研究界定 ,将为砾岩油藏的开发水平提供技术支持     

随钻气侵检测仪在胜利油田的应用

简要介绍了随钻气侵检测仪的结构特点、工作原理、现场模拟试验及应用情况。中原油田全尺寸实验井和胜利油田６口井的现场试验及应用结果表明，该仪器能实现早期气侵检测，比常规方法检测到气侵的时间明显提前，对高压气井和复杂地层井控具有重要的现实意义。     

Undergraduate Summer Research in Structural Engineering

For the last seven years, a summer Research Experiences for Undergraduates site in structural engineering, funded by the National Science Foundation, has operated at the University of Alabama at Birmingham. During this time, 33 students from 22 colleges and universities have participated in the site. Participants are recruited nationally and have come from as far away as California and Puerto Rico. The program is intended to provide students interested in graduate studies with an introduction to research methods, and to provide students who will not continue their studies past a bachelor of science in civil engineering with a better understanding of how research provides the theoretical foundation of engineering practice. Students work individually with faculty on literature reviews, computer modeling, laboratory testing, and field research. Three students have researched structural failure case studies and the technical and ethical lessons to be learned from them. Participants also have the opportunity to tour construction sites and construction material manufacturers’ and fabricators’ facilities. During the past three years, an ethics seminar series has been added. At the end of the program, students prepare research papers and Web pages documenting their work and present their results to faculty, students, and other participants.
