Drawing in Time: Processes of Design and Fabrication

Drawing embeds time within itself, notating changes in space and duration. For Babak Bryan and Henry Grosman , founding partners of BanG studio in Long Island City, New York: ‘The drawing is a result of process, but it also describes process.’ It is only through this temporal practice that an essential connection is developed between drawing and building. With the widespread adoption of building information modelling (BIM), linear graphic representation finds itself in crisis, challenged by the static inertia of the model. As Bryan and Grosman describe, the well-crafted drawing remains essential to their studio's approach informing the method of ‘making and remaking’.     

Palm Oil: A New Ethics of Visibility for the Production Landscape

The explosion of the palm oil industry in recent decades has transformed vast swathes of the Malaysian and Indonesian countryside. Milica Topalovic , Assistant Professor of Architecture and Territorial Planning at ETH Zurich, asserts that the resulting agro-industrial landscapes challenge the very concept of what is rural, and considers how such areas should be conceptualised.     

山东省平阴县阎庄铁矿床地质特征及成因分析

阎庄铁矿位于汶上—东平成矿带北侧,为探讨该矿床成矿标志,通过研究矿床地质特征,分析其成因并总结找矿标志,对区内找矿工作具有借鉴价值。矿体赋存于山草峪组中,其形态受基底背斜控制,呈似层状产出,岩浆岩对矿体的连续性起破坏作用。矿床成因为与新太古代火山活动及区域变质作用有关的沉积变质型铁矿床,泰山岩群变质岩系与磁异常是该类型矿床的找矿标志。     

辽河西部凹陷稠油油藏特征及其成因探讨

辽河油田西部凹陷稠油资源丰富,分布广泛,类型多样,地化特征显著。根据原油的成熟度、生物降解程度及生物降解后油气的注入情况等多元因素,将该区稠油划分为原生稠油、降解型稠油及降解—混合型稠油。西部凹陷稠油成因主要为生物降解作用,水洗作用和氧化作用则促进了原油稠化,而温度、地下水、化学条件及构造条件等是控制原油降解程度的主要因素。     

含油气盆地中深层碎屑岩储层异常高孔带研究进展

异常高孔带是指由于经历异常地质作用而形成的孔隙度高于正常压实条件下最大孔隙度的异常高孔隙度储层相对集中发育带,是含油气盆地中深层油气勘探的甜点。国内外学者对其开展了大量有益的研究,总结其研究成果对于指导深部油气藏勘探有着重要的意义。首先总结了近些年全球范围内异常高孔带的研究现状,主要包括异常高孔带概念、划分方案、类型、储集空间、成因机制及预测等。研究表明,异常高孔带的分布通常利用孔隙度正常压实趋势线(或相当的趋势线)进行确定。根据孔隙类型及含量,异常高孔带具有原生孔隙型异常高孔带和次生孔隙型异常高孔带2种类型,原生孔隙型异常高孔带储集空间以原生孔隙为主,保孔型地质因素是其形成的主控因素;次生孔隙型异常高孔带储集空间以次生孔隙为主,溶蚀增孔作用是其形成的主控因素。然后对中国含油气盆地深层异常高孔带的特征和成因机制进行了系统总结,认为其分布广泛,类型多样;其分布具有地层深度范围大、时代跨越尺度大、盆地类型多样和沉积相类型丰富等特点;其类型兼具原生孔隙型和次生孔隙型。最后指出了目前研究中存在的一些问题和今后的研究趋势。

天山南区块白垩系-第三系低阻气层特征及成因分析

塔里木盆地天山南区块白垩系—第三系碎屑岩气藏为高含凝析油的天然气藏,储层普遍具有低电阻率特征,其中下第三系苏维依组、库姆格列木群和下白垩统巴什基奇克组气层电阻率值一般为1~3Ω·m,下白垩统亚格列木组气层电阻率值一般为4~9Ω·m。气层电性特征表现为：①接近或略高于水层电阻率;②低于围岩电阻率;③具有“高阻侵入”特征,即侵入带电阻率一般大于地层电阻率(R_xo＞R_t）,反映在3条电阻率曲线上具有RFOC＞RILM＞RILD的特征。通过钻井录井、测井及试油气资料分析认为,储层复杂的岩相岩性和气藏流体特征为低阻气层的形成提供了有利地质条件;高含水饱和度及高地层水矿化度是形成低阻气层的主要原因;高地层温度可能对储层具有一定的降阻效应。

??Dolomite is the most important rock type for the development of the Ordovician effective reservoirs in the Ordos Basin. Its genesis remains controversial due to its complex and variable rock texture and occurrence. In this paper, through analysis of macroscopic regional geological background, microscopic rock texture, mineralogy, and geochemistry, the Ordovician dolomites in this area are divided into three types, i.e. micritic–fine powder crystal, coarse powder crystal, and fine (medium) crystal. It is pointed out that they were formed in three different dolomitization diagenetic environments, namely, penecontemporaneous dolomization by evaporative pumping, mixture dolomitization of freshwater and magnesium-rich brine, and seepage-reflux dolomitization, respectively. In terms of horizon and spatial distribution, they represent the features of "strata-controlled" and "region-specific". The analysis of genesis provides the following findings. First, the three types of dolomitization are correlated to certain extent in terms of temporal–spatial evolution. In other words, they were all originated along with the deposition of gypsum mineral under evaporation background. Second, the main pore types, i.e. dissolved pores, intercrystalline pores, and organic framework, were respectively formed in three types of dolomites. They generally distribute in "specific" type of dolomite, which indicates that the pore genesis is closely related to dolomitization diagenesis environment. Third, the development and distribution of effective dolomite reservoirs is mainly subject to three types of elements, such as primary sedimentary faices belts, diagenetic environment controlling regional dolomitization, and sequence boundary caused by variation of relative sea level.
