海上勘探开发一体化技术研究及应用——以北部湾盆地涠西南凹陷为例

北部湾盆地涠西南凹陷为高成熟的勘探开发区,面临目标搜索难度大、储量发现难度大、建产周期长、油田储采比低等问题,常规的勘探—开发接力模式无法满足储量和产量增长的要求。为保证油田可持续开采,提出海上勘探开发一体化模式,总结了集目标搜索技术、目标评价技术、井位钻探技术三位一体的技术体系。目标搜索技术是在基础地质规律指导下,与勘探和开发紧密结合,通过新钻井发现及老井复查,利用区带潜力目标搜索、随钻跟踪过程潜力目标搜索、评价过程潜力目标搜索等技术,在油田内部及周边开展潜力目标搜索。目标评价技术集成发展了6项一体化评价技术,大大提高了目标评价的精度及成功率。井位钻探技术的"开发评价井钻探模式"包括开发模式和勘探模式。在井位钻探技术的指导下,北部湾盆地涠西南凹陷开发评价井的实施取得了显著的成效,已钻井为37口,成功钻井达31口,成功率为84%,实现了增储上产。围绕涠西南凹陷E油田开展技术应用,共搜索出12个潜力目标。在E油田的中1区块、南2区块和南3区块,开发评价井（E-B5井、E-B1S1井、E-A7S2井和E-12d井）的部署和顺利实施进一步推动了海上勘探开发一体化技术体系的应用。     

适用于页岩气藏储量的几种计算方法

页岩气在形式上以游离气和吸附气并存,存储空间上为孔隙和裂缝同存。页岩气藏的产气机制主要为游离气的扩散以及吸附气的解吸。基于此,分析页岩气储量计算的方法,如类比法、静态法、动态法。重点分析动态法,探讨不同方法的适用条件。分析页岩气储量计算中的几个关键因素,简要介绍其确定方法。     

Sensitivity to electricity consumption in urban business and commercial area buildings according to climatic change

Recently, urban high temperature phenomenon has become a problem which results from human activities, the increase in energy consumption, and land-cover change in urban areas. As extremely hot weather caused by urban high temperature continues, demand for power is increased and results in the degradation of electricity reserves. The current trend in climate change, regardless of the summer and winter power demand, is likely to have much effect on the power demand. Thus, sensitivity to electricity consumption in urban areas due to climate change was researched. The results show that, 1) the basic unit of the sensitivity to electricity consumption in the target areas is 1.25–1.58W/(m²·°C); 2) The maximum sensitivity is recorded at around 8:00 pm in the area crowded with commercial and business area. And in the business area, electricity consumption load is even from 9:00 am to 6:00 pm.

TN型双通道燃烧器在燃用劣质煤锅炉中的应用

针对当前电煤价格升高、煤质下降,许多电厂在燃用劣质煤时,锅炉出现频繁灭火、管壁超温、投油助燃等问题,研制了TN型双通道燃烧器。TN型双通道燃烧器是在原双通道燃烧器原理基础上,增加了“多突扩”和“煤粉浓缩”技术,使更多的煤粉在燃烧器中预热、预燃,其稳燃能力更强。应用TN型双通道燃烧器,可大大提高锅炉的稳燃能力和煤质适应性,降低锅炉助燃油用量,使锅炉运行的安全性和经济性均得到大幅提高,为电力企业降低发电成本提供可靠的技术保障。

Faculty Begin to Replace Textbooks with “Freely” Accessible Online Resources

ABSTRACT

More and more students are financially unable to acquire, or deliberately choose to go without course textbooks. A variety of commercial and noncommercial initiatives have materialized to address the student success challenge of learning material access inequality in the classroom. There is a gap between how higher education faculty plan to teach a course and the actual learning environment that exists in practice. Faculty are beginning to experiment with freely available and licensed library materials as a substitute for commercial textbooks and course packages to address the failure of textbook publishers to reach a price point that entices students to buy textbooks. The results thus far are promising. Some courses can be delivered today using only “freely available” learning resources, some using a mix of fee based and free, while others cannot be delivered using any freely available resources at all due to a lack of availability.

油气储量可升级性评价方法探讨

以油气预测储量区块为研究对象,提出利用升级难易程度指数值定量评价储量可升级性。研究认为,影响预测储量升级性的主要因素是储量品位,其他因素对储量升级性有影响,但影响程度相对较小。预测储量升级性可采用对主评因素、辅评(背景)因素、关联因素的因子赋值方法进行升级难易程度指数值计算,利用指数值大小确定可升级性及升级顺序。
