2016年国际原油价格分析与趋势预测

在回顾2015年国际原油市场主要发展历程的基础上,从两方面对2016年油价走势进行了发展态势展望和预测分析。研究认为:受全球经济形势、供需基本面因素的主要作用,在产量相对过剩情况下,尽管2015年油价已经下跌至成本价水平,但2016年油价整体还将呈现下降态势或将持续在低位震荡。预计2016年Brent、WTI原油均价为40~50美元/桶,并且两市明显价差将消失。     

2016年石化产业前景预测与展望

通过对2015年石化产业的发展进行回顾,分析2016年影响石油生产行业、油服行业、炼油与化工行业、储运销售行业及一体化公司业绩的因素变化情况,据此对2016年石化产业的前景作出预测:受累于低油价,石油生产行业承压;油服行业保持盈利,但增速放缓;炼油与化工行业可抓住机会,实现盈利;储运销售行业业绩可实现稳中有升;一体化公司缘于业务差异,分化会更加明显。     

油页岩灰渣用作水泥混合料的胶砂试验

3种油页岩灰渣(油厂灰、电厂灰、粉末灰)用作水泥混合材料可不同程度地改变水泥的性能。以3种油页岩灰渣作为掺料,按10%,20%,30%(质量比)3种比例代替水泥混合料中的部分水泥,通过水泥混合料的胶砂试验确定试块的抗压、抗折强度以及脆性系数。结果表明：用油页岩灰渣作水泥混合材料来提高试块的抗折、抗压强度及抗裂性能是可行的,其中电厂灰灰渣在10%掺量时,其试块抗折、抗压强度总体要优于纯水泥试块;3种油页岩都能够提高试块的抗裂性能,粉末灰灰渣在30%掺量时试块的抗裂性能最好。     

Using simulation to manage project supply chain in the offshore oil and gas industry

This paper is aimed at comparing simulation against spreadsheets as decision support tools to properly manage project supply chain in the offshore oil and gas industry. The paper presents a case study related to the problem of sizing a chain for pipeline laying from an offshore field in the Barents sea to the Russian coast. Results obtained through a spreadsheet developed by an oil and gas company have been compared to the ones gathered from an ad hoc simulation model. A simulation model with no stochastic variable has been introduced: results are quite similar to the ones of the spreadsheet, which allowed to validate the simulation model. However, the spreadsheet cannot take into account the continuous move of the pipe-lay vessel while laying the pipes and it does not consider stochastic variables whose effect in real life is not negligible. Both weaknesses above are discussed.     

The use of performance measurement as a basis for project control of offshore modification oil and gas projects

The methods presented in this article are based on the qualitative and quantitative analysis of close-out data drawn from a portfolio of 38 modification projects. The primary premise is that modification projects are intrinsically subject to quantity and complexity growth during the course of detailed engineering as a consequence of the indeterminate interface with the existing facility. The normative project control routines need to be supplemented by material take-offs-based weight monitoring as a basis for re-estimation and re-calibration of the project baselines as detailed engineering proceeds in order to mitigate this uncertainty as early as possible. Similarly, estimating needs to be based on norms drawn from performance measurement of modification work rather than extrapolations from greenfield projects, particularly the work performed on the platforms. This article presents a portfolio of project control methods based on the performance measurement principle covering the short term of single projects as well as the longer term multi-project perspective.     

基于多重分形理论的原油市场耦合关系研究

以美国西德克萨斯轻质原油现货价格（WTI）、英国北海布伦特原油现货价格（Brent）、中东迪拜原油现货价格（Dubai）和中国大庆原油现货价格（Daq）为代表性的研究对象,运用耦合消除趋势波动分析法（CDFA）对国内外原油市场之间耦合关系的多重分形特征进行实证分析。实证结果表明：原油市场之间的耦合关系具有明显的多重分形特征;厚尾分布和长记忆性是产生多重分形特征的主要原因;无论就长记忆性而言,还是就厚尾分布而言,WTI对原油市场耦合关系多重分形特征的影响最为突出。     

发展和完善我国原油期货市场

中国原油期货上市意义重大,上市时机已经成熟。发展和完善我国原油期货市场,需要:打破石油市场的垄断,吸引广泛的市场参与主体;建立更具开放性、操作性更强的交易机制;建立并完善石油战略储备体系;大力发展资本市场,构建多层次金融市场体系,推进石油金融一体化;多视角择机推动"石油人民币"体系的建立,促进人民币的崛起等等。     

世界能源格局新趋势与我国石油战略对策

世界范围内的石油需求市场、供应、资本的多元化,显示世界能源格局已拉开了新一轮大调整的序幕.世界主要强国纷纷出台了本国的能源发展战略.我国的能源安全形势严峻,我国必须尽快实施部署"重组、开源、节流、重储、保运、合作"的能源安全战略,以确保我国能源供应的安全.     

国际油价不确定性与中国经济增长——基于GARCH-in-Mean SVAR模型的实证研究

通过建立双变量的GARCH-in-Mean SVAR模型,将代表国际油价不确定性的变量——油价变动率的条件标准差,引入结构向量自回归模型(SVAR),来检验国际油价不确定性对中国经济增长的影响。研究表明,国际油价的不确定性尚未对中国经济增长造成显著的负面影响。此外,油价不确定性延长了油价变动对中国经济产生的负面影响,相应缩短了其正面影响,而且,中国经济增长对油价正负冲击的响应具有不对称性。     

Fractionally integrated ARMA for crude palm oil prices prediction: case of potentially overdifference

Dealing with stationarity remains an unsolved problem. Some of the time series data, especially crude palm oil (CPO) prices persist towards nonstationarity in the long-run data. This dilemma forces the researchers to conduct first-order difference. The basic idea is that to obtain the stationary data that is considered as a good strategy to overcome the nonstationary counterparts. An opportune remark as it is, this proxy may lead to overdifference. The CPO prices trend elements have not been attenuated but nearly annihilated. Therefore, this paper presents the usefulness of autoregressive fractionally integrated moving average (ARFIMA) model as the solution towards the nonstationary persistency of CPO prices in the long-run data. In this study, we employed daily historical Free-on-Board CPO prices in Malaysia. A comparison was made between the ARFIMA over the existing autoregressive-integrated moving average (ARIMA) model. Here, we employed three statistical evaluation criteria in order to measure the performance of the applied models. The general conclusion that can be derived from this paper is that the usefulness of the ARFIMA model outperformed the existing ARIMA model.
