＂Continuous＂ tight gas reservoirs are those reservoirs which develop in widespread tight sandstones with a continuous distribution of natural gas. In this paper, we summarize the geological features of the source rocks and ＂＇continuous＂ tight gas reservoirs in the Xujiahe Formation of the middle- south transition region, Sichuan Basin. The source rocks of the Xul Member and reservoir rocks of the Xu2 Member are thick （Xul Member： 40 m, Xu2 Member： 120 m） and are distributed continuously in this study area. The results of drilled wells show that the widespread sandstone reservoirs of the Xu2 Member are charged with natural gas. Therefore, the natural gas reservoirs of the Xu2 Member in the middle-south transition region are ＂continuous＂ tight gas reservoirs. The accumulation of ＂continuous＂ tight gas reservoirs is controlled by an adequate driving force of the pressure differences between source rocks and reservoirs, which is demonstrated by a ＂one-dimensional＂ physical simulation experiment. In this simulation, the natural gas of＂continuous＂ tight gas reservoirs moves tbrward with no preferential petroleum migration pathways （PPMP）, and the natural gas saturation of＂continuous＂ tight gas reservoirs is higher than that of conventional reservoirs.

针对帘线钢夹杂物控制,通常选择长时间软吹处理提高钢水洁净度,但会导致镁碳砖侵蚀加剧。通过工业生产试验,使用FEI Explorer 4自动扫描电镜,研究LF精炼结束后软吹时间对帘线钢盘条夹杂物成分、数量的影响;并采用贝卡标准评分和神户标准Max-T(ave)评分进行盘条夹杂物评价。结果表明,LF精炼结束后软吹时间45 min与软吹时间25 min生产工艺对比,盘条中尺寸大于3μm的氧化物夹杂成分基本类似,夹杂物密度分别为135个/100 mm^(2)、103个/100 mm^(2),LF精炼结束后软吹时间25 min工艺夹杂物数量密度略低。扩大对比试验数量,盘条贝卡标准评分和神户标准Max-T(ave)评分表明,LF精炼结束后软吹时间20~25 min的夹杂物控制并未变差或略有改善趋势。帘线钢中低熔点夹杂物的控制主要通过控制Al含量、精炼渣等工艺参数,而导致最终产品失效的夹杂物往往与内生夹杂物类型不一致,对于帘线钢而言,可以考虑降低LF精炼结束后软吹时间。

针对间歇发酵过程缓慢时变和非线性等特点,提出一种基于滑动窗技术的多向核主元分析(MWMKPCA)方法。该方法结合了核主元分析(KPCA)和滑动窗口技术的优点,其中KPCA能有效解决过程数据的非线性问题,保证数据信息抽取的完整性;而滑动窗口技术能有效避免MKPCA在线应用时预报未来测量值所引入的误差,提高监控性能。对于已判断正常的新批次过程数据,将其加入模型参考数据库进行更新,从而提高间歇过程性能检测的准确性。将该方法应用到工业青霉素发酵过程的监控中,并与MPCA、MKPCA方法的监测性能进行了比较。结果表明:该方法能有效提取过程变量间的非线性关系,降低运行过程的误报率,对缓慢时变的间歇过程具有更可靠的检测性能。

近年来四川盆地上三叠统须家河组发现了大量岩性气藏及构造-岩性复合气藏,且普遍含水。通过开展流体性质与特征研究,发现了水溶气脱溶成藏的天然气组分变化依据与碳同位素特征变化依据:远离气源中心区的水溶气脱溶气藏甲烷含量高、干燥系数较大、异构烷烃与正构烷烃比值大、甲烷与乙烷碳同位素较重。水溶气脱溶成藏主要存在地层抬升减压降温脱溶成藏与水溶气顺层侧向运移减压脱溶成藏两种模式,川中地区具有水溶气脱溶成藏所需的有利条件,即丰富的水溶气资源、地层强烈抬升、流体减压降温及地层水矿化度局部浓缩等。水溶气的脱溶成藏是大川中地区大面积岩性气藏发育及天然气规模聚集的重要成藏机理之一,也是合川—安岳地区须一段烃源岩发育很差而须二段却能形成大规模天然气聚集的重要原因。
