伊拉克米桑油田Abu区块储层岩性为碳酸盐地层,缝洞非常发育,而且地层压力系数低,漏失是钻井过程面临的主要难题。结合相关地质取心和电测成像资料,在总结分析前期堵漏工艺的基础上,室内对现有可酸溶复合堵漏材料配方进行了优化,将酸溶率提高到75%以上,室内模拟实验承压能力提高到7 MPa以上,并进一步优化形成了适应该区块的堵漏施工工艺。通过现场5口漏失井的试验表明,优化后的可酸溶堵漏配方明显提高了现场堵漏成功率,进一步缩短了钻井周期。   相似文献

The notion of ‘smart cities’, with their ubiquitous linked sharing of data and observation, can be both problematic and simultaneously utopian. Tridib Banerjee , Professor Emeritus of Public Policy at the University of Southern California (USC) where he previously held the James Irvine Chair in Urban and Regional Planning, explores the recent adoption of the concept, particularly in the Global South. Notably, Le Corbusier's modernist city of Chandigarh in India has just been named a smart city. What will this mean for law and order, culture, and urban vitality for its inhabitants in coming years?  相似文献

The timing of petroleum generation of source rocks is recognized to investigate the maturation level of the proven potential source formations for oil preservation dead lines, and predict the levels of thermal maturity of the studied sequences in terms of hydrocarbon generation and expulsion. For theses purposes four thermal burial history and maturity profiles were constructed of the Abu Gharaig-1 SW Umbaraka-1, GPZ-1, and GPX-1 wells. The results showed Abu Roash and Bahariya formations are immature to mature source rocks and have poor to fair potential to generate both oil and gas and still are within the early stage of hydrocarbon generation till the present time. Alam El Bueib and Masajid formations bear mature source rocks and have good generating capability for generating both oil and gas and entered the oil window since Cretaceous to Miocene times and lies within oil and gas windows at present time. Khatatba Formation bears a mature source rock and has good generating capability for both oil and gas and entered the oil window during Late Cretaceous to Eocene times.  相似文献

What is a City?     
On the 75th anniversary of Lewis Mumford's rhetorical essay ‘What is a City?’, Austin Williams asks whether we risk defining cities out of existence. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

Mathematics in design is most often associated with its visual manifestation in geometrical surfaces and elements. The finely tuned ambient qualities of a space, necessary for environmental performance, may not be so apparent, but can involve the application of many branches of mathematics. Martha Tsigkari, Adam Davis and Francis Aish of Foster + Partners' Specialist Modelling Group bring this to the fore by describing how at Al Raha Beach development in Abu Dhabi and the City of Justice in Madrid environmental considerations were interpreted through analytical numerical data.

Affect is not just about mood and fantasy; at its best, it is an aesthetic provocation that can generate a profound questioning of the nature of reality. The 19th-century Realist writers and artists understood this – and its political implications – well. After examining the theme with reference to the writings of an international array of cultural critics, architect Michael Young – cofounder with Kutan Ayata of the New York-based studio Young & Ayata – presents a project by his firm that is subtly designed to trigger affective sensations of defamiliarisation.  相似文献

Established 15 years ago under the leadership of Hugh Whitehead, the Specialist Modelling Group (SMG) at Foster + Partners has an unrivalled reputation internationally as an in-house research group. It provides Fosters with expertise in computation, geometry and fabrication, as well as in environmental analysis and simulation. Xavier De Kestelier, co-head of SMG and partner at Foster + Partners, describes how the group has developed and expanded over the last few years, growing the range of its specialist knowledge that informs projects as diverse as the YachtPlus Boat Fleet (2009), Kuwait International Airport (2009-) and Masdar Institute of Science and Technology (2010).  相似文献

This paper outlines how a corrosion map of zinc was developed for Abu‐Dhabi. It presents inputs into the model being databases of RH, rainfall, salt deposition and time of wetness and explains how these inputs are combined to product the corrosion map of Abu Dhabi. It is found that although the corrosion rate generally falls with distance from the Arabian Gulf, corrosion rates in the hinterland of the central coast and in the Hajar Mountains are higher than would be expected from a simple dependence on distance from the coast. The higher corrosion rates around the central coast are associated with the extremely low rainfall while those in the Hajar Mountains may be associated with the transport of airborne salinity from the Gulf of Oman. In general, the corrosion rates in Abu Dhabi are much higher than observed at sites in Australia and South East Asia with similar levels of airborne salinity which is attributed to the much higher quantities of salt that are retained on metal surfaces in Abu Dhabi (relative to Australia) due to the fact that rain washing events, which are frequent and effective in Australia, are very infrequent in Abu Dhabi.  相似文献
