The endogenous hypochlorous acid(HOCI) has been evidenced in a variety of cellular courses. However, the role of HOCI in most pathophysiological processes still keeps unclear because of the limited detecting tools. In this work, we presented the pre- paration of a phenothiazine-derived fluorescent probe CIO-1 for HOCI detection with a cyanopyridinium moiety to improve its water solubility and lengthen its emission wavelength. The HOCI-promoted oxidation of sulfur atom in the probe resulted in a 460-fold emission intensity enhancement at 635 nm with high selectivity and sensitivity(detection limit: 1.12 nmol/L). The rapid response(5 s) also endowed the probe with real-time detection ability. Successfully, CIO-1 was devoted to the bioimaging of endogenous HOCI in inflamed RAW 264.7 cells and 5-fluorouracil-treated MCF-7 cells.

Fouling deposition problem on heat transfer surface is widely distributed in the field of energy and chemical industry,and microbial fouling is a common fouling type in heat exchanger.In this article,the surface modification was used for inhibiting or mitigating the microbial fouling deposition on heat exchange surface.Firstly,the experimental system for real-time monitoring the fouling deposition process was built,and then the Ni-P modified surface was prepared.Further,the slime forming bacteria(SFB)microbial fouling characteristics and corresponding influencing factors on Ni-P modified surface were investigated experimentally.The results indicated that Ni-P modified surface had an excellent fouling inhibition property.Comparing with carbon steel,Ni-P modified surface reduced the fouling heat resistance by 80%.Accordingly,the influencing factors of microbial fouling deposition including temperature,flow rate and microbial concentrations were discussed.With cooling water temperature increasing given in the experiment arrangement,the microbial fouling resistance was increased first and then decreased,while with bacteria concentration and flow rate increasing,the fouling resistance was increased and decreased separately.The work can provide experimental reference for the fouling inhibition surface development and fouling inhibition mechanism study.

Based on the compilation and analysis of the lithofacies and paleogeography distribution maps at present and paleoplate locations during six key geological periods of the Mesozoic and Cenozoic,the lithofacies and paleogeography features and their development laws were expounded.Based on our previous research results on lithofacies and paleogeography from Precambrian to Paleozoic,we systematically studied the features and evolution laws of global lithofacies and paleogeography from the Precambrian and their effects on the formation of source rocks,reservoirs,cap rocks and the distribution of oil and gas worldwide.The results show that since Precambrian,the distribution areas of uplift erosion and terrestrial clastic deposition tended to increase gradually,and increased significantly during the period of continental growth.The scale of coastal and shallow marine facies area had three distinct cycles,namely,from Precambrian to Devonian,from Carboniferous to Triassic,and from Jurassic to Neogene.Correspondingly,the development of shallow carbonate platform also showed three cycles;the lacustrine facies onshore was relatively developed in Mesozoic and Cenozoic;the sabkha was mainly developed in the Devonian,Permian and Triassic.The Cretaceous is the most important source rock layers in the world,followed by the Jurassic and Paleogene source rocks;the clastic reservoirs have more oil and gas than the carbonate reservoirs;the basins with shale caprocks have the widest distribution,the most abundant reserves of oil and gas,and the evaporite caprocks have the strongest sealing capacity,which can seal some huge oil and gas fields.

Global recoverable resources of heavy oil and oil sands have been assessed by CNPC using a geology-based assessment method combined with the traditional volumetric method, spatial interpolation method, parametric-probability method etc. The most favourable areas for exploration have been selected in accordance with a comprehensive scoring system. The results show:(1) For geological resources, CNPC estimate 991.18 billion tonnes of heavy oil and 501.26 billion tonnes of oil sands globally, of which technically recoverable resources of heavy oil and oil sands comprise 126.74 billion tonnes and 64.13 billion tonnes respectively. More than 80% of the resources occur within Tertiary and Cretaceous reservoirs distributed across 69 heavy oil basins and 32 oil sands basins. 99% of recoverable resources of heavy oil and oil sands occur within foreland basins, passive continental-margin basins and cratonic basins.(2) Since residual hydrocarbon resources remain following large-scale hydrocarbon migration and destruction, heavy oil and oil sands are characterized most commonly by late hydrocarbon accumulation, the same basin types and source-reservoir conditions as for conventional hydrocarbon resources, shallow burial depth and stratabound reservoirs.(3) Three accumulation models are recognised, depending on basin type: degradation along slope; destruction by uplift; and migration along faults.(4) In addition to mature exploration regions such as Canada and Venezuela, the Volga-Ural Basin and the Pre-Caspian Basin are less well-explored and have good potential for oil-sand discoveries, and it is predicted that the Middle East will be an important region for heavy oil development.

当下,全球深水、超深水已经成为国际石油公司跨国油气勘探开发的重要领域。在分析巴西国际油气合作基础、发展现状及趋势的基础上,通过计算全球主要深水油气资产的单桶盈亏平衡油价,认为巴西深水-超深水极具勘探开发成本优势。对比分析6大国际石油公司和中国石油公司在巴西的布局策略,认为中国石油公司在作业者身份获取及勘探资产部署两方面有所欠缺。提出了新形势下中国石油公司在巴西的投资策略,即通过深化与巴西国家石油公司的战略合作,将巴西项目打造成海外深水石油核心产区。具体措施包括:提前购买多用户地震数据,超前评价,有效支撑未来永久招标模式的投标决策和优质项目获取;通过参股、联合作业到独立作业“三步走”战略,补足深水作业短板;以多种方式获取勘探开发各类资产,快速培植核心产区。

换热设备颗粒污垢一般指悬浮在流体中的固体颗粒在换热面上的积聚。开发了一种Ni-P-TiO_(2)防垢型复合改性表面,并将之用于板式换热器抑制纳米MgO颗粒污垢在换热表面的积聚。基于搭建的板式换热器颗粒污垢热阻动态监测实验系统,研究了不同冷却水流速(0.1~0.3 m/s)、入口温度(30~40℃)及纳米MgO浓度(100~400 mg/L)对Ni-P-TiO_(2)复合改性换热表面抑垢特性的影响。结果表明,随着流速的增加,污垢热阻渐近值减小了27.85%~34.41%;随着冷却水入口温度的升高,污垢热阻渐近值减小了25.15%~39.14%;随着MgO颗粒浓度的增加,热阻渐近值减小了26.15%~45.36%。结合Ni-P-TiO_(2)复合改性表面的表面能分析了其表面的抑垢性能,发现制备的Ni-P-TiO_(2)复合改性表面的表面能与纳米MgO颗粒污垢层的表面能相接近,符合Zhao提出的“最优表面能”抑垢理论。与常规板式换热器不锈钢表面相比,Ni-P-TiO_(2)复合改性表面不仅抑制了颗粒污垢的积聚,还降低了颗粒污垢的固着强度,使得积聚其上的颗粒污垢更容易被剥离换热表面,实现了换热表面持久高效抑垢。

中东阿拉伯板块自寒武纪以来为一个构造相对稳定的块体,油气储量占全球重要地位。近年来,深部古生界储层成为油气勘探新发现的主要层系。本文通过调研中东区域地质、含油气盆地地质资料,结合油气藏层位及分布特征,编制阿拉伯板块寒武纪、奥陶纪、志留纪、泥盆纪、早二叠世、晚二叠世等6个地质时期的岩相古地理图,并分析对油气富集特征的控制作用。研究结果表明:(1)寒武纪-志留纪,阿拉伯板块整体以陆相-浅海相沉积环境为主,早志留世的快速海侵形成热页岩,为古生界油气生成提供了雄厚的物质基础;(2)泥盆纪-石炭纪,海西构造事件造成抬升剥蚀,使志留纪烃源岩能够发生垂向/侧向运移至二叠系储层;(3)早二叠世以碎屑岩沉积为主,晚二叠世为海相和局限海沉积环境,形成了以碳酸盐岩储层和蒸发盐岩盖层为主的优质储盖组合;(4)已发现油气藏主要分布在寒武系-志留系陆相碎屑岩、下二叠统陆相-海陆过渡相碎屑岩和碳酸盐岩以及上二叠统海相碳酸盐岩储层中,上二叠统碳酸盐岩为最重要的储层,志留系热页岩广泛分布、基底继承性构造和前寒武系盐穹隆为古生界油气运聚提供了有利条件。

西非被动大陆边缘盐盆地是目前世界油气勘探的重点和热点地区,近年来该区发现的油气与盐构造密切相关。西非被动大陆边缘盐盆地主要集中于安哥拉—喀麦隆段,普遍发育厚层盐层,厚度最大可达1500m,分布范围平均宽度约300km。盐盆地的发育具有明显的分段性,横向上可以将盐盆地划分为坡上伸展区和坡下挤压区。伸展区又可以细分为坡上构造带、生长断层带以及底辟构造带,以发育掀斜地块、滚动构造和龟背斜构造为特征,宽约100～150km;挤压区主要发育盐席、盐舌、逆冲断层和短波褶皱,宽为100～200km。伸展区和挤压区都具有良好的勘探前景,伸展区油气储量比挤压区略大。与盐构造相关的圈闭包括拱形圈闭、盐刺穿侧向封堵和断层遮挡圈闭、不整合圈闭、构造-岩性圈闭等,其中拱形圈闭是非洲西部最有潜力的圈闭。
