“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。     

西湖凹陷深层低渗-致密气藏“甜点”类型划分及成因探讨

低渗-致密气藏开发的关键是“甜点”的识别和预测,为探索海上少井、深层低渗-致密气藏“甜点”类型及成因,指导油气田勘探开发,利用岩心观察,铸体、阴极发光、扫描电镜等薄片鉴定,粒度分析,核磁共振,高压压汞,恒速压汞,孔渗测试和元素分析等多种手段对东海陆架盆地西湖凹陷X气田“甜点”进行研究。首先对研究区“甜点”定义进行探讨,并根据理论产能、物性、孔隙结构和束缚水含量将“甜点”分为3类：Ⅰ类“甜点”为高产气藏,以Ⅰ类孔隙结构为主,束缚水饱和度大多处于22%~57%;Ⅱ类“甜点”为中产气藏,储层中主要发育Ⅱ类孔隙结构,其次为Ⅰ类孔隙结构,少见Ⅲ类孔隙结构,束缚水饱和度大多处于45%~55%;Ⅲ类“甜点”为低产气藏,主要以Ⅲ类孔隙结构为主,发育少量Ⅳ类孔隙结构,束缚水饱和度大多处于45%~55%。认为Ⅰ类和Ⅱ类“甜点”能够实现现阶段经济有效开发,Ⅲ类“甜点”为后期开发的“潜力层”。研究认为,埋深是控制“甜点”发育的决定性因素,研究区4 000 m以深基本不发育Ⅰ类和Ⅱ类“甜点”;沉积环境是控制“甜点”发育的内因;事件性沉积作用及成岩作用是Ⅰ类和Ⅱ类“甜点”的重要影响因素;溶蚀作用是Ⅲ类“甜点”的主控因素;构造运动是研究区气藏“甜点”形成和保存的必要条件。     

准噶尔盆地页岩油“甜点区”评价与关键技术应用——以吉木萨尔凹陷二叠系芦草沟组为例

非常规油气资源已成为准噶尔盆地油气勘探的新领域之一。以吉木萨尔凹陷二叠系芦草沟组为着手点,开展页岩油形成与富集的地质条件、“甜点”评价及预测技术方法等研究。通过总结近年来吉木萨尔凹陷芦草沟组页岩油的勘探成果,梳理出页岩油“甜点”形成的关键地质条件：①广泛分布的优质烃源岩;②致密的储层中发育物性较好的“甜点”段;③源岩层系内频繁的源储薄互层构成源内高效的成藏组合。明确芦草沟组页岩油“甜点”受控于烃源岩、岩性、物性、含油性、敏感性、脆性、地应力各向异性等参数,并基于现场实验参数建立了其评价标准。以“甜点”分布的地质需求为导向,形成了一套多参数“甜点”分布预测技术,涵盖地质、测井、物探以及工程等方面。形成的地质认识丰富了我国陆相页岩油地质理论认识,相关技术方法为准噶尔盆地其他地区页岩油领域以及国内陆相盆地页岩油的评价提供借鉴。     

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.

Styrenated urethane oil synthesis via CuAAC “click” chemistry approach

In this study, a novel route for the modification of sunflower oil-based partial triglycerides with styrene (St) was described. For this purpose, in the first step, copolymers of St and 4-chloromethyl styrene (P(St-co-CMS)) were synthesized by free radical polymerization (FRP) and controlled/living radical polymerization (nitroxide mediated radical polymerization (NMRP)) methods. In the second step, chloro groups of these samples were transformed into azido groups by using NaN₃/DMF and then azido groups were coupled with propargyl alcohol to achieve hydroxyl functional polystyrene chain (PSt-OH) via Cu(I)-catalyzed 1,3-dipolar azide-alkyne cycloaddition (CuAAC) “click” chemistry approach. Finally, alcohol groups of PSt-OH and the partial glyceride (PG) were combined by the reaction with toluene 2,4-diisocyanate (TDI). As a result, styrenated urethane oil (PG-TDI-PSt) was obtained as an oil-based binder. The structures were determined by FT-IR, ¹H NMR and GPC analyses, and film properties of the products were examined according to the related standards. (PG-TDI-PSt) gave good film properties, and therefore could be considered as an applicable oil-based binder.     

On the Genesis of the Marshall-Olkin Family of Distributions via the T-<i>X</i> Family Approach: Statistical Modeling

In the last couple of years, there Has been an increased interest among the statisticians to define new families of distributions by adding one or more additional parameter(s) to the baseline distribution. In this regard, a number of families have been introduced and studied. One such example is the Marshall-Olkin family of distributions that is one of the most prominent approaches used to generalize the existing distributions. Whenever, we see a new method, the natural questions come in to mind are (i) what are the genesis of the newly proposed method and (ii) how did the proposed method is obtained. No doubt, the Marshall-Olkin family is a very useful method and has attracted the researchers. But, unfortunately, the authors failed to provide the explanation about the genesis of the method that how this family of distributions is obtained. To address this issue, in this article, an attempt Has been made to provide a straight forward computation about the genesis of the Marshall-Olkin family that somehow completes its derivation. The genesis of the Marshall-Olkin family is based on the T-X family approach. Furthermore, we have showed that other extensions of the Marshall-Olkin family can also be obtained via the T-X family method. Finally, a real-life application form insurance science is presented to illustrate the newly proposed extension of the Marshall-Olkin family.
