川东北元坝地区长兴组气藏成藏模式探究

作为川东北目前最重要的油气勘探层系,元坝长兴组气藏在该地区油气勘探开发中的作用日渐凸显出来。川东北元坝地区长兴组气藏是由生物礁滩相储层形成的大型构造岩性圈闭气藏,随着该现代勘探开发技术和一体化模式的不断推进,该气藏的成藏模式已经日趋成熟。本文将对川东北元坝地区长兴组气藏的成藏模式进行分析,并在此基础上提出一些建设性意见,以期为该气藏的勘探和开发提供一些参考。     

长岭断陷东部腰英台深层气田成藏特征

腰英台气田的主体构造由断层控制的构造-岩性气藏,为了搞清该气田的构造、储层和气藏特征,在区域构造演化分析的基础上,应用构造解析和储层分析技术,对工区主体构造进行了构造、储层特征研究,探讨了深层气藏的成藏特征,分析认为,腰英台主要为受构造、岩性双重控制的构造—岩性气藏,从而构建了本区复式油气成藏模式,对指导本区及类似地区油气勘探具有实际意义。     

东濮凹陷西部斜坡带胡庆地区成藏潜力分析

东濮凹陷西部斜坡带胡庆地区为东倾断阶构造,已发现油气主要集中在二台阶的构造圈闭之中,勘探程度高,靠近洼陷带的一台阶发现较少,勘探程度低.随着勘探工作的不断深入,一台阶的勘探潜力成为中原油田近些年来重点关注的问题.综合分析认为:一台阶靠近生烃中心、具有优越的油源条件;受华北运动Ⅱ幕构造运动影响,西部斜坡带表现出两次生烃、两期成藏的特点,东营组时期长垣断层作为运移通道将洼陷带油气运移至二台阶成藏,东营期之后长垣断层停止活动,具有封闭油气的能力,晚期生成的油气主要聚集在一台阶.     

川西拗陷知新场构造带须家河组成藏地质分析及勘探思路

知新场构造带位于川西坳陷东斜坡上,断裂极其发育。该区经历了多年勘探,目前在主体构造高部位钻有CQ128、CQ173、CQ171等井,在钻探过程中见到了良好的油气显示,但测试未获工业气流。在三维地震解释和对区内已钻井及邻区典型气藏解剖基础上,分析区内成藏地质条件及主控断裂封堵性,明确了知新场构造带勘探思路为"由构造高部位向构造两翼、由构造气藏向隐蔽岩性气藏、由泥中找砂向砂中找砂",指出构造两翼是须家河组勘探的重点区域,岩性圈闭是下步勘探的重要目标。     

准噶尔盆地车排子地区石炭系油气勘探潜力

准噶尔盆地石炭系是重要的油气勘探领域,但整体勘探程度低。通过系统分析车排子地区石炭系石油地质特征,落实油气资源潜力,对指导勘探有重要意义。通过最新钻井资料,认为该区石炭系发育火山岩孔隙、溶洞和裂缝三类储集空间,油源为来自昌吉凹陷的中下二叠统和下侏罗统烃源岩,油气运聚通道主要为断层和不整合面。认为有利的构造背景、有利火山岩相带、断裂发育情况、优势输导条件为优选勘探有利区的主要评价标准,指出车排子地区三个近南北向展布的断裂发育区为有利油气聚集带。

陆相致密砂砾岩气藏富集主控因素

新场构造须四下亚段发育砂岩、砂砾岩和砾岩储层,储层纵横向非均质性极强,甜点平面分布不均.通过油气富集规律研究,建立了三种不同岩性天然气富集模式,并提出了油气富集的三个主控因素:古构造控制了油气富集带的形成、优质储层控制气藏展布、裂缝控制气井产量.寻找有利的相带、有利岩性组合是储层预测的关键,预测裂缝发育区是高效勘探开发的关键,该地质认识及基于此认识获得的预测成果在勘探开发实践中取得了较好的效果.     

新场须家河组有利区综合预测

尽管新场构造需要四段满足油气成藏的基础地质条件,但已有钻井揭示该地区油气平面分布不均,油气富集规律十分复杂。通过研究,新场构造须四段油气富集的3个主控因素为:优质储层控制气藏展布;裂缝为高产气井的重要因素;古构造控制了油气富集带的形成。基于主控因素,采用叠前地质统计学反演方法开展储层预测,采用基于构造应变、基于地层组合特征变化、优势频带地震相干、横波分裂等技术开展综合裂缝预测;运用petromod软件恢复古构造。最后通过多参数的综合分析,实现了对天然气富集区的综合预测。     

Reactions in Stabilizer and Between Stabilizer and Nitrocellulose in Propellants

HPLC analysis of the stabilizer is one of the major methods in use for surveillance testing of diphenylamine (DPA) stabilized propellants. Often 0.2% DPA is used as a minimum content for safe propellants. In most cases the propellant can be stored much longer after this limit has been reached without any risk for self‐ignition. We report here about a reaction where DPA bonds to nitrocellulose, leaving a non extractable aromatic stabilizing compound left in the propellant, resulting in a longer time to autocatalysis than predicted. Diphenylnitramine is discussed as a possible intermediary compound occurring from the reaction between DPA and nitrocellulose. This should add to a better understanding of the degradation processes in propellants.

Designer enzyme and cell applications in industry and in environmental monitoring

Renewed world interest in enzyme biotechnological industries now derives from the expectation that many new biocatalysts will be created by genetic engineering associated with protein engineering designer techniques, or by chemical modification of existing enzymes by use of protein tailoring methods. The biocatalysts produced are mainly enzymes, abzymes (catalytic antibodies) and synthesis (synthetic analogues or mimics), and these will be used in industry, synthesis, therapy: and in bioanalysis of components of foodstuffs, and the environment including water, air and soil. The biocatalysts, including whole cells, are firstly incorporated into a particular bioreactor form by use of enzyme engineering techniques such as immobilization, and are then used, as appropriate, to modify their substrates. Improved processing or enhanced products are thereby achieved in the case of manufacturing industry: or monitoring signals are generated, often in the form of a measurable change in current flow, in the case of environmental biosensors. Designer enzymes and cells can be made now for identified applications where the presently available biocatalysts are inadequate, incompatible or uncompetitive.     

Differences in color naming and color salience in Vietnamese and English

The accepted model of color naming postulates that 11 “basic” color terms representing 11 common perceptual experiences show increased processing salience due to a theorized linkage between perception, visual neurophysiology, and cognition. We tested this theory, originally proposed by Berlin and Kay in 1969. Experiment 1 tested salience by comparing unconstrained color naming across two languages, English and Vietnamese. Results were compared with previous research by Berlin and Kay, Boynton and Olson, and colleagues. Experiment 2 validated our stimuli by comparing OSA, Munsell, and newly rendered “basic” exemplars using colorimetry and behavioral measures. Our results show that the relationship between the visual and verbal domains is more complex than current theory acknowledges. An interpoint distance model of color‐naming behavior is proposed as an alternative perspective on color‐naming universality and color‐category structure. © 2003 Wiley Periodicals, Inc.

EZH2 Down-Regulation Exacerbates Lipid Accumulation and Inflammation in in Vitro and in Vivo NAFLD

Non-alcoholic fatty liver disease (NAFLD) is one of the most prevalent, chronic liver diseases, worldwide. It is a multifactorial disease caused by complex interactions between genetic, epigenetic and environmental factors. Recently, several microRNAs, some of which epigenetically regulated, have been found to be up- and/or down-regulated during NAFLD development. However, in NAFLD, the essential role of the Polycomb Group protein Enhancer of Zeste Homolog 2 (EZH2), which controls the epigenetic silencing of specific genes and/or microRNAs by trimethylating Lys27 on histone H3, still remains unknown. In this study, we demonstrate that the nuclear expression/activity of the EZH2 protein is down-regulated both in livers from NAFLD rats and in the free fatty acid-treated HepG2. The drop in EZH2 is inversely correlated with: (i) lipid accumulation; (ii) the expression of pro-inflammatory markers including TNF-α and TGF-β; and (iii) the expression of miR-200b and miR-155. Consistently, the pharmacological inhibition of EZH2 by 3-Deazaneplanocin A (DZNep) significantly reduces EZH2 expression/activity, while it increases lipid accumulation, inflammatory molecules and microRNAs. In conclusion, the results of this study suggest that the defective activity of EZH2 can enhance the NAFLD development by favouring steatosis and the de-repression of the inflammatory genes and that of specific microRNAs.
