Volatile organo-halogen trace analysis in beverages by thin-layer headspace enrichment and electron-capture gas-chromatography

Applicability of thin-layer headspace (TLHS) procedure giving an aqueous concentrate and also classical purge and trap (PT) in off-line mode to isolate and enrich volatile organohalogen compounds in common beverages was tested. Both enrichment tech-niques were used in combination with gas chromatography – electron capture detection (GC-ECD). TLHS, combined with direct aqueous injection (DAI)-GC-ECD, proved applicable in the determination of volatile organohalogen compounds in all studied beverages, while the PT in a version with no preliminary sample pre-treatment was of limited applicability. Detection limits of the TLHS-based procedure were in the order of 1 ppt. Content of volatile organohalogen compounds in a number of beverages available on the Polish market including mineral waters, beers, juices, carbonated and non-carbonated soft drinks, etc. was determined by means of TLHS-DAI-GC-ECD.     

四川盆地中部上三叠统香溪群岩性油气藏圈闭类型及其特征

四川盆地川中地区构造平缓,大型断裂欠发育,已发现的油气藏与背斜关系并不十分密切。研究认为,川中地区香溪群主要发育岩性圈闭,根据圈闭形成主控因素,结合香溪群沉积前的古地貌特征和裂缝发育特点,将川中香溪群岩性圈闭划分为4种类型:①与地层尖灭相关的地层—岩性圈闭;②与沉积—成岩相变密切相关的成岩—岩性圈闭;③与古地貌有关的差异压实作用形成的岩性圈闭;④与断层转化调节相关的裂缝—岩性复合圈闭。其中成岩—岩性圈闭和地层—岩性圈闭,是川中香溪群最重要的、分布最广泛的圈闭类型。     

Bio-derived fuels may ease the regeneration of diesel particulate traps

Particulate is the most problematic emission from diesel engines. To comply with environmental regulations, these engines are often equipped with particulate traps, which must be regenerated frequently for the sake of efficiency. The regeneration is commonly achieved by rising the temperature in the trap till the particulate self-ignites. However, this method implies energy losses and thermal shocks in the trap. Alternatively, catalysts and additives have been recently considered for reducing the ignition temperature of particulate, but these techniques suffer from poisoning and undesirable byproducts. The present experimental study shows that the ignition temperature of particulate from seed-derived oils (SO) and from blends of SO with diesel fuel oil (DO) can be lower than that of particulate from neat DO. If substantiated by more extensive studies, such finding could have noteworthy implications on the future of fuels and traps.

准噶尔盆地三台-北三台地区第三系勘探潜力分析

从沉积及储层组合、油气运移系统等方面全面剖析了准噶尔盆地三台-北三台地区第三系油气成藏条件，建立了成藏模式，对未钻探区勘探潜力进行了预测；通过分析，认为该区第三系储层物性主体差，断裂更多地表现为封闭性，导致沟通深部油气源的运移体系不畅，致使第三系圈闭不能有效捕获和储集油气。圈闭又比较匮乏，主体勘探潜力不大。北25井西背斜紧邻多期活动的甘诃子北断裂，第三系可能发育较好的储层，相对有利，北25井西背斜应是钻探第三系的首选目标。     

饮用水中挥发性三卤甲烷(THM)_s测定方法的改进

岩性圈闭预测方法及应用

随着油田勘探技术的不断进步和勘探目标的日益深化，地质目标从寻找大构造、发展到寻找微幅度构造和非构造的隐蔽油气藏。以往的研究结果表明，岩性预测方法由于受到地震资料分辨率及技术条件等因素的限制，其研究方法及对成果的认识都有其局限性，从而使预测的合理性和精度都不高，因此，本文以高分辨率地震资料为基础，应用测井、钻井及地震等资料，从沉积微相分析入手，建立了不同砂体类型的地质及地震正演模型，并根据地震反射波组特征、地震反演的阻抗值及其它地震属性参数，综合确定出研究区域的砂体变化及其分布规律。总结出一套针对薄互层特点的岩性圈闭识别技术，并在大庆长垣以西古龙和英台—大安地区的实际应用中取得了明显的效果。
