柴达木盆地东坪气田基岩储层裂缝建模方法研究

东坪气田基岩气藏是罕见的非常规裂缝性气藏，有效模拟天然裂缝的发育状况及展布特征十分困难。针对这一问题，在分析东坪气田基岩气藏储集空间特征的基础上，确立了基岩储层DFN离散裂缝模型的建立思路。先基于成像测井解释的裂缝倾角、裂缝方位角等裂缝特性参数，将东坪基岩储层裂缝分为两组走向近似垂直的天然裂缝，分别模拟了两组天然裂缝的密度分布。再以裂缝密度曲线作为目标曲线、地震综合属性体作为趋势约束体，建立了DFN离散裂缝分布模型。通过提取裂缝密度、孔隙度及渗透率等属性参数，研究了东坪基岩储层裂缝的分布特征，发现裂缝主要受断层控制，平面上和纵向上均存在强的非均匀发育特性。最后，运用东坪基岩储层生产动态特征和气藏数值模拟的产量历史拟合效果检验了DFN离散裂缝模型对基岩储层的适用性。研究成果可为非常规基岩储层的裂缝模拟提供强有力的技术手段。     

论重力能源及其开发

通过回顾人们认识物体受地球重力作用的历史,指出了牛顿万有引力定律应用于近地球表面物体重力研究时,因忽略重力场中介质的存在而丧失了突破保守力限制的可能性。通过建立介质重力场并引入现实世界中实际存在的物体状态(密度)的变换,证明重力是保守力的固有观念是可以突破的。这一观念的突破,使重力能源成为可能。围绕着开发重力能源,研究提出了开发的手段。

Daily activity of the white-clawed crayfish,Austropotamobius pallipes (Lereboullet): a comparison between field and laboratory studies

The daily activity of the threatened crayfish, Austropotamobius pallipes (Lereboullet), was studied both in the field, through direct counts of active animals along a stream section, and in the laboratory, by means of actographs. In the field, crayfish were mostly found after dawn, with a slight but significant difference among seasons. In winter, only two specimens were seen to be active. Distinguishing among size classes, medium-sized crayfish were more abundant in spring and summer, while large ones mostly occurred in autumn. The former always concentrated their activity at night-time; to the contrary, larger specimens were more active late at night in spring and at dusk in autumn. Sex-ratio, analysed only in summer, was balanced throughout the 24h. Nocturnal activity, although differing among seasons, was similar in size classes, temperatures and sexes. In the laboratory, activity (evaluated as photo-cell interruptions) increased with temperature and occurrence throughout a 24-h cycle (the highest peak shifting from midnight to dusk). Only in the laboratory, a low peak occurred at dawn, but disappeared when a shelter was available. The interaction between the response of A. pallipes to temperature and its nocturnal habit is examined. Questions still remain on the adaptive value of the environmental factors influencing the cycle of freshwater decapods' activity.

Objective styles in northern field science

Social studies of science have often treated natural field sites as extensions of the laboratory. But this overlooks the unique specificities of field sites. While lab sites are usually private spaces with carefully controlled borders, field sites are more typically public spaces with fluid boundaries and diverse inhabitants. Field scientists must therefore often adapt their work to the demands and interests of local agents. I propose to address the difference between lab and field in sociological terms, as a difference in style. A field style treats epistemic alterity as a resource rather than an obstacle for objective knowledge production. A sociological stylistics of the field should thus explain how objective science can co-exist with radical conceptual difference. I discuss examples from the Canadian North, focussing on collaborations between state wildlife biologists and managers, on the one hand, and local Aboriginal Elders and hunters, on the other. I argue that a sociological stylistics of the field can help us to better understand how radically diverse agents may collaborate across cultures in the successful production of reliable natural knowledge.
