平落坝香二气藏成藏条件剖析
,秦成明
天然气工业 , 1995,
Abstract: ?平落坝气田是川西龙门山前缘发现的又一个中型气田.文章从沉积构过发展、孔隙演化、油气运聚史、圈闭类型和特征、储层地质模型、封盖性能、水文地质条件等方面剖析了平落坝香二气藏的成藏机制.该构造紧邻上三叠统生烃凹陷,本身也具有良好的生烃条件,早期聚气条件好,晚第三纪以来有丰富的"晚成气"补给;属短轴高丘状背斜构造类型,褶皱适中、圈闭完整,无破坏性大断层切割;香二段气层上覆香三段泥质岩厚度大,宏观特征和微观结构研究认为属封盖能力强的优良盖层;香二段储层发育6种类型次生储集空间,孔隙结构较好,选择性溶蚀导致信层的非均质,具较高的有效储集概率;张开、半充填低角度裂缝发育,与次生溶蚀孔形成有机的配置,裂缝是重要储集空间和渗滤通道,是气并产能的重要控制因素;天然气的保存条件优越.
白马庙气田蓬莱镇组气藏气井产能控制因素研究

天然气工业 , 2003,
Abstract: ?白马庙气田蓬莱镇气藏储层致密,孔隙结构复杂,非均质性强,单井产能低,研究储层特征和受控因素,加强储层改造方是气藏效益开发的出路。储层精细研究揭示,气井产能受沉积相和构造条件控制;高、中产井与大而厚、物性好的河口坝、河道砂坝沉积微相有关,纵向上具很强的层段性,主产层集中在ⅳ~③、ⅲ~③两套砂组,其钻探成功率分别达82%和100%;平面上多分布于主体构造和东南鼻状突起,二者高、中产能井分别占30%和70%。在深入的地质研究和储层压裂评层选井的基础上,采用多层打开、分层压裂、多层合采的方法可提高气井产能,并形成了一套行之有效的压裂评层选井的综合配套技术。采用该技术优选出19口井,已实施5口井全获成功,气产量成倍或十几倍增加,其中白浅45井气无阻流量高达18×104m3/d,白浅38井投产165d净增产值100余万元。
凝析气藏反凝析规律研究应强调保本凝析油含量
李如金,,胡雪涛,李绍基
天然气工业 , 1995,
Abstract: ?根据国内外同行经验,通过对气藏、气井的凝析油生产分析和地下烃体系的相态变化规律理论计算,将中坝须二气藏反凝析作用划分为五个阶段,对该气域生产过程中凝析油含量的衰减趋势进行了预测,根据轻烃回收经济概算和理论提出保本凝析油含量值和对应的流动压力值,该指标对年度配产具有决策意义.
平落坝须二段气藏单井产能递减分析
李建,陈古明,杨春宝,陈颖丽,钟贞广,
天然气工业 , 2005,
Abstract: ?气井在生产过程中,产能下降的原因有地层压力下降引起的自然递减和产层物性变化引起的额外递减,采用不同时期试井得到的产能方程可以计算两种递减各占的比重。文章研究了气井产能方程的结构,看出气井在理论条件下,二式中的a、b值不发生变化;但当地层出水、井底积液等情况时,a、b值会发生变化。通过对平落坝须二气藏单井产能方程中的a、b值的变化分析,认为须二气藏各井无论是否出水,均存在额外递减,亦即各井的产层在生产过程中均有不同程度的伤害;但气井出水会造成有效渗透率下降,生产压差额外增加,导致气井产能下降,产量递减幅度明显增大,这对单井影响较大;建议对存在井底积液的气井尽快考虑带液措施,以避免产层进一步受到伤害。
《三国演义》的女性主义批评视角的建构与分析
Construction and Analysis of Feminist Criticism Perspective in The Romance of Three Kingdoms
 [PDF]


World Literature Studies (WLS) , 2015, DOI: 10.12677/WLS.2015.34024
Abstract:
女性主义的文学批评模式主要从三个视角看待文学作品:女性人物、女性作者和女性读者。虽然人类的文学长河汹涌流淌的是男性波涛,女性主义的浪花却从一开始就伴随着男性波涛跳跃辉映,一路延绵不息直至融汇入海。《三国演义》是中国文学的鸿篇巨著,尽管发端于男权鼎盛的社会历史时期,仍不乏荧光闪烁着女性主义的妖娆魅影。针对《三国演义》作一番女性主义批评视角的建构和分析,将会是对文学领域本就始终存在的女性主义因素的一次集中发掘和完整审视,从而更加丰富对《三国演义》的认识和鉴赏框架。
Literary criticism pattern of feminism mainly regards literary works from three perspectives: female character, female writer and female reader. The human literature flows with the main stream of masculine water, but the feminine waves have been sparkling all along the river until it merges into the ocean. The Romance of Three Kingdoms is a great work of the Chinese literature, in which the historical times of masculine boom are reflected while feminine charms have glittered. The analysis on The Romance of Three Kingdoms with feminist criticism would be a concentration on and an examination of the feminism that has been integrated into human literature at its very beginning, enriching the appreciation and study on the works.
高校外语专业教学模式的转变探讨—基于互联网优势
On the Changes to the Teaching Pattern of Foreign Language Discipline in Colleges or Universities—Based on the Advantages of the Internet
 [PDF]


Advances in Education (AE) , 2016, DOI: 10.12677/AE.2016.62009
Abstract:
高校外语专业的教学模式始终是与时俱进的,外语人才的培养目标和社会需求以及外语教学的技术发展都会对教学模式产生不同程度的影响。然而,自互联网技术全球普及以来,我国的高校外语专业教学模式却没有足够地充分利用互联网技术带来的便利与革新。如何才能结合高校外语专业的教学实际,充分发挥互联网海量资源库的强大作用,进一步提高教学质量,应当成为当前高校外语专业师生积极探讨、深入研究的课题。
The teaching pattern for learning a foreign language as a college discipline is evidently changing to adapt itself to the society where it is conducted, because the objective and demand of a society for talents with a good command of a foreign language as well as the technical development in language teaching are always casting on it variable influences. Now that the Internet technologies have been popular around the world, the above-mentioned pattern in our colleges and universities, however, has not been fully pushed to a new era by that popularity of the Internet yet. Therefore, it should be a topic for research by the teachers and students working in the foreign language program of a college or university how the foreign language discipline of a college or university can be further improved by the hugeness of information the Internet has been ready to offer.
突然断索后双吊索形式自锚式悬索桥安全分析

Abstract: 吊索是决定悬索桥结构安全的关键构件,已建悬索桥的吊索普遍存在锈蚀的现象,在锈蚀与疲劳荷载作用下,吊索可能发生突然断裂.已有研究及工程实例均表明,单根吊索断裂后其余的吊索有连续断裂的危险,从而导致全桥的倒塌.使用双吊索可以改善断索对悬索桥结构安全的影响.为研究双吊索对悬索桥安全性的改善程度以及断索后悬索桥结构的动力响应,基于非线性静力和动力分析方法,以某200 m的混凝土自锚式悬索桥为例,进行了悬索桥断索后结构的响应研究.研究结果表明,双吊索能大幅度降低断索后悬索桥结构的响应,从而提高了全桥在运营维护阶段的安全性.研究结论可为悬索桥吊索的更换、维修和加固提供参考.
Hangers are essential security parts of the suspension bridge structure. It is a general phenomenon that hangers have serious corrosion problems, and the hangers may fail suddenly under fatigue and corrosion effect. Existing research and engineering examples show that the breakage of a hanger can lead to the successive breakage of other hangers and then result in the collapse of the whole bridge at worst. Dual-shaped hanger can improve the safety of the suspension bridge related to the hanger failure. To research into the safety improvement and dynamic response of the suspension bridge after the breakage of the dual-shaped hanger, the study on the response of suspension bridge after hanger breakage is carried out using nonlinear static and dynamic methods, based on a 200 m self-anchored suspension bridge with concrete girder. The analytical results show that the dual-shaped hanger can reduce the response of suspension bridge after hanger breakage and improve the safety of the whole bridge during the service and maintenance stage. The conclusion can also provide a reference for the replacement, maintenance and reinforcement of suspension bridge hangers.

碾压堆石体成拱机理分析
,贤德
重庆大学学报 , 2002, DOI: 10.11835/j.issn.1000-582X.2002.03.027
Abstract: 碾压堆石体作为一种重要筑坝材料,其成拱效应始终是碾压堆石坝安全问题的焦点之一。碾压堆石体随堆积形式和施工工艺的差异而具有不同的工程特性,其破坏服从Coulomb-Mohr破坏准则。针对碾压堆石体的特殊施工工艺对涪陵城区移民迁建防护工程的碾压堆石体民拱机理进行了理论研究,并用FLAC有限差分程序对成拱机理进行了数值分析,结果表明碾压堆石体在一段时间的沉降之后的确可形成压力拱,压力拱正上方的土压力值小于两侧土压力,并承担部分上覆土层的自重及外加荷载。
