准噶尔盆地致密砾岩储层特征及“甜点”预测——以中佳地区佳木河组二段一砂组储层为例

准噶尔盆地西北缘中佳地区佳木河组二段一砂组致密砾岩储层厚度大,分布范围广,试油气结果不理想,储层“甜点”区分布规律不清。基于录测井、分析化验以及叠前三维地震等多种资料,建立地质“甜点”与工程“甜点”判别参数,揭示“甜点”特征与采气能力相关关系,优选“甜点”表征参数,进行储层“甜点”预测及评价。研究结果表明：中佳地区佳木河组二段一砂组储层为低孔隙度、特低渗透率的致密砾岩储层,渗流条件整体偏差。致密砾岩储层脆性指数普遍大于60%,储层可压性好,更容易获得高产。“甜点”区储层具有低伽马值、高电阻率、低密度、低中子孔隙度、高声波时差值、较高孔渗,高含气饱和度,低纵横波速度比、低波阻抗以及脆性指数值较高的特征。依据储层综合评价分类特征结合纵横波速度比、孔隙度及脆性指数参数反演结果识别刻画2类“甜点”区分布范围,其中Ⅰ类“甜点”区分布在扇三角洲内前缘相带中的中佳7—新光1井区,总面积达50 km²;Ⅱ类“甜点”区主要分布于中佳7—新光1井区外围区,面积达48 km²。部署在Ⅰ类“甜点”区的ZJHW201井获得日产70×10⁴ m     

Methodology for security analysis of data-processing systems

Use of the logic programming language PROLOG assists in tracking functional relationships through complex networks to ensure that all products receive a security classification consistent with the operative security model. The language also permits computing work factors for data products. In some cases, these work factors may modify the levels of protection required.     

Information as a corporate asset

The author explains the need for and necessity of information for running a complex multinational company like Philips. He gives a short overview of the organization and structure of Philips, employing almost 400,000 people, and its world-wide activities. He deals with specific aspects and problems regarding the production, storage and distribution of a large range of Philips products, i.e., how this huge task was tackled in the early EDP days, and what difficulties and troubles had to be overcome. Gradually a new generation of managers has developed who are able to handle the possibilities of computers and automated information systems.However, the multinational Philips covers thousands of separate units which cannot operate on their own. For business-information exchange they have to communicate in a well-defined language based on stadardized data elements. Data-bases, in the future interconnected by a world-wide communications network, contain data that represent valuable and indispensible information for the Philips company: a real corporate asset.With some reserve the writer dares to make predictions about the future of automation, yet mentions some clear trends and draws interesting conclusions.     

The Space-Time of Pre-emption: An Interview with Brian Massumi

The philosopher Brian Massumi is known for his explorations of experience, art, media theory and politics and has recently turned his attention to understanding the impact that sustained fear has on perception in a post-9/11 world. In an interview with guest-editor Charles Rice , Massumi defines threat by distinguishing it from real danger and how it manifests itself in both civil and military spaces of pre-emptive action that are primed to the possibilities of attack.

“三个代表”重要思想与中国共产党的先进性

贯彻“三个代表”重要思想,核心和灵魂是永葆党的先进性。先进性是工人阶级先锋队的本质属性,是党得以存在和发展的根本依据,是党能够得到最广大人民信赖和拥护的根本条件。党的先进性是具体的历史的,是随着时代和实践的发展而发展的。因此始终保持党的先进性,无论什么时候都是党的建设的核心问题,因而也是新世纪我们要建设一个什么样的党和怎样建设党的核心问题。     

致密油平台式“工厂化”水平井优化设计——以松辽盆地三肇凹陷肇源地区Y63井区扶余油层为例

松辽盆地三肇凹陷肇源地区扶余油层具有资源量大、储集层致密、普遍含油且连续分布的特点。但产能问题一直是制约该区致密油勘探开发的难点。针对肇源地区Y63“甜点”区,应用大量测录井、试油及化验分析资料,明确FⅡ₁砂层组“甜点”地质特征,通过地震属性、地质统计学反演,精细刻画“甜点”砂体边界,开展平台式“工厂化”水平井设计。实钻结果表明,已完钻6口水平井钻遇油层934~1 177m,平均为1 070m,与周边直井相比,提高产能5~12倍,证实平台式“工厂化”水平井部署方式的优越性和可行性。     

Electromagnetic transients in the control system of output parameters of a solar power plant in Tajikistan Central Asia region

At present, as the demand for electricity increases in all sectors, there is an urgent need to introduce alternative renewable energy sources into modern energy systems. Renewable energy sources, which consist of solar (photovoltaic, PV), wind and hydro power, are key alternative sources of “green energy’’ energies, but it can also be used to produce “green” hydrogen. Thanks to scientific and technological progress, the cost of photovoltaic solar radiation converters is constantly decreasing at a high rate, which makes it possible to build solar power plants of sufficiently large capacity. In the coming decades, solar energy will become an incentive for the economic development of countries that have the maximum “solar” resource. The Republic of Tajikistan is one of these countries with a high potential for solar energy.The article presents an analysis of the resources and potential of solar energy in the Republic of Tajikistan. The study of electromagnetic transients in networks with photovoltaic solar power plants is performed. The main equations, simulation model and calculations of transients are presented, taking into account changes in voltage on DC buses. An algorithm for controlling the system of automatic control of output parameters is proposed. The analysis of dynamic and static modes in parallel operation of a solar power plant with the grid is carried out. A block diagram and computer model is constructed in the MATLAB package together with Simulink and Power System Blockset.
