Abstract It is possible to predict the behavior of fluids in permeable and porous medium under different operating conditions by using reservoir models. Since geological data and reservoir properties can be defined most accurately by reservoir models, it has been accepted as a reliable prediction tool among reservoir engineers. In this study, a gas reservoir has been modeled with IMEX Module of CMG Reservoir Simulator. Rock properties, gas composition and certain production data were entered to the model as input data and the measured field data were matched with simulated ones. After the 5 year depletion of the reservoir by vertical wells, the average reservoir pressure dropped from an original reservoir pressure of 2150 psi to 1200 psi. This depleted reservoir was planned to be used for gas storage purposes. The remaining gas was used as cushion gas during the conversion of this reservoir to an underground gas storage field. Afterwards, horizontal wells were defined in the model and certain production/injection scenarios were simulated for the gas storage operation.
摘要利用储层模型可以预测不同工况下渗流和多孔介质中的流体行为。由于储层模型可以最准确地定义地质数据和储层性质,因此已被油藏工程师接受为可靠的预测工具。利用CMG油藏模拟器的IMEX模块对某气藏进行建模。将岩石性质、气体成分和一定的生产数据作为输入数据输入到模型中,并将现场实测数据与模拟数据进行匹配。经过5年的直井开采,该油藏的平均压力从原来的2150 psi降至1200 psi。这个枯竭的储气库计划用于储气。在将该储层改造为地下储气库的过程中,剩余的天然气被用作缓冲气。随后,在模型中定义了水平井,并模拟了储气作业的某些生产/注入场景。

As part of a major project on studying the operational challenges in gas-to-liquids (GTL) transportation through the Trans Alaska Pipeline System (TAPS), the wax appearance temperatures (WAT) of GTL products and the Alaska North Slope Crude (ANSC) and their blends were measured. The WAT measurements of GTL products were based on the American Society for Testing and Materials (ASTM) D3117 standard, whereas the WAT measurements of ANSC and its blends with the GTL products were measured by the viscometry technique. The reliability of the viscometry technique was ascertained by comparing the WATs of the colorless GTL products measured by the ASTM D 3117 method. The WATs measured by the viscometry technique and the ASTM D3117 method were found to be in excellent agreement.
作为研究跨阿拉斯加管道系统(TAPS)气转液(GTL)运输操作挑战的主要项目的一部分,测量了GTL产品和阿拉斯加北坡原油(ANSC)及其混合物的蜡样温度(WAT)。GTL产品的WAT测量基于美国材料试验协会(ASTM) D3117标准,而ANSC及其与GTL产品的共混物的WAT测量采用粘度测定技术。通过比较ASTM D 3117法测定的无色GTL产品的WATs,确定了粘度测定技术的可靠性。用粘度法和ASTM D3117法测定的wts值非常吻合。

Turkey's natural gas (NG) production is very small and is almost all imported. Turkish natural gas production in 2000, 23 billion cubic feet (Bcf), met around 4% of domestic natural gas consumption requirements. NG consumption is estimated at around 700 Bcf in year 2002, accounting for around 17% of Turkey's total energy consumption. Turkish natural gas demand had been projected to increase extremely rapidly in coming years. Country oil production is 50,674 barrels per day (bbl/d) of which 46,674 bbl/d was crude oil in 2002. In 2002, oil consumption was 635,000 bbl/d and net oil imports was 584,326 bbl/d in Turkey. Oil provides around 43% of Turkey's total energy requirements.
土耳其的天然气(NG)产量非常小,几乎全部进口。土耳其2000年的天然气产量为230亿立方英尺(Bcf),满足了国内天然气消费需求的4%左右。据估计,2002年的天然气消费量约为7000亿立方英尺,约占土耳其总能源消费量的17%。预计未来几年土耳其的天然气需求将以极快的速度增长。2002年,该国石油产量为50,674桶/天,其中46,674桶/天为原油。2002年,土耳其的石油消费量为63.5万桶/天,石油净进口量为584326桶/天。石油提供了土耳其总能源需求的43%。

Abstract For conventional energy technologies, energy and exergy analyses have been performed and have yielded useful results. Besides this, for advanced energy technologies, the use of energy and exergy analyses can be expected to provide meaningful insights into performance that will assist in achieving optimal designs. In this regard, this study describes the modeling and analysis of sectoral energy and exergy utilization. The sectors considered are subgrouped into four main sectors, namely, utility, industrial, commercial-residential and transportation. The modeling presented here is expected to assist in the simulation and optimization activities and also in the planned studies towards increasing energy efficiencies in the sectors studied.

It has been proposed that biodiesel liquids be used as blending stocks for middle distillate ground transportation fuels by the Department of Defense. The U.S. Navy is considering allowing up to 20% biodiesel to be added as a blending stock to petroleum diesel fuels. It is important for operational consideration to look at the many problems this could present. Among the more important considerations are storage stability, filterability, fuel solubility, oxidative stability and induced instability reactions. This article reports on the use of recycled soybean derived fuel liquids. The fuel liquid was derived from recycled restaurant cooking oil with no added antioxidant after reprocessing. We compare this biodiesel in blends of both 10% and 20% with stable and unstable middle distillate fuels for storage stability, oxidative stability, solubility, and chemical instability results.
美国国防部建议将生物柴油液体用作中间馏分地面运输燃料的混合原料。美国海军正在考虑允许在石油柴油燃料中添加高达20%的生物柴油。考虑到这可能带来的许多问题,对业务考虑是很重要的。更重要的考虑因素是储存稳定性、过滤性、燃料溶解度、氧化稳定性和诱导不稳定性反应。本文报道了再生大豆衍生燃料液体的应用。该燃料液体是由回收的餐厅食用油中提取的,经过后处理后不添加抗氧化剂。我们将混合10%和20%的生物柴油与稳定和不稳定的中间馏分燃料进行了存储稳定性、氧化稳定性、溶解度和化学不稳定性的比较。

Effect of Pressure on Combustion Kinetics of Heavy Oils 压力对重油燃烧动力学的影响
Pub Date : 2005-07-01 DOI: 10.1080/00908310490478791

In this study, 16 experiments were conducted to study the effects of pressure on crude oil oxidation in limestone medium. Karakus (29°API), Beykan (32°API), Bati Raman (12°API), Camurlu (12°API), Adiyaman (26°API), Garzan (28°API) and Raman (18°API) crude oil from Turkish oil fields were used. The mixture of limestone and the crude oil was subjected to a controlled heating schedule under a constant flow rate of air. The produced gas was analyzed for its oxygen and carbon oxides contents. The results of reaction kinetics showed that the molar CO2/CO ratio values of fuel combustion increased with increasing pressure. A decrease in the atomic H/C ratio with an increase in temperature was observed for all runs. Results indicate that oxygen consumed increases with increasing operating pressure. This means more fuel is burnt by increasing the pressure, which is due to the effect of pressure on the volatility of the oil components. Because increasing pressure will depress oil volatility, the fuel availability would increase. This also suggests that distillation might be the dominant mechanism for fuel deposition. A trend of increase in activation energy values by increasing pressure is observed.
本研究通过16个实验研究了压力对石灰岩介质中原油氧化的影响。采用土耳其油田的Karakus (API为29°)、Beykan (API为32°)、Bati Raman (API为12°)、Camurlu (API为12°)、Adiyaman (API为26°)、Garzan (API为28°)和Raman (API为18°)原油。将石灰石和原油的混合物在恒定的空气流速下进行控制加热。对产生的气体进行了氧和碳氧化物含量分析。反应动力学结果表明,燃料燃烧的摩尔CO2/CO比值随压力的增大而增大。在所有运行过程中,观察到原子H/C比随着温度的升高而降低。结果表明,氧气消耗量随操作压力的增加而增加。这意味着通过增加压力来燃烧更多的燃料,这是由于压力对油成分挥发性的影响。因为压力的增加会降低石油的波动性,燃料的可用性就会增加。这也表明蒸馏可能是燃料沉积的主要机制。观察到活化能值随压力的增加而增加的趋势。

With a young and growing population, low per capita electricity consumption, rapid urbanization and strong economic growth, for nearly two decades, Turkey has been one of the fastest growing power markets in the world. Projections by Turkey's Electricity Generating and Transmission Corporation (TEAŞ), a public company which owns and operates 15 thermal and 30 hydroelectric plants generating 91% of Turkey's electricity, indicate that rapid (as high as 10% annual) growth in electricity consumption will continue over the next 15 years. Turkey's electric production was 160 billion kilowatt-hours [kWh] in year 2002. Turkey may need to triple its total electric power generating capacity to around 64 gigawatts (GW) by 2010. According to the Ministry of Energy and Natural Resources (MENR), this would also require investments of $4–$4.5 billion per year.
土耳其人口年轻且不断增长,人均用电量低,城市化速度快,经济增长强劲,近二十年来一直是世界上增长最快的电力市场之一。土耳其发电和输电公司(TEAŞ)是一家拥有并运营15座火电厂和30座水力发电厂的上市公司,发电量占土耳其总发电量的91%。该公司的预测表明,未来15年,电力消耗将继续快速增长(年增长率高达10%)。2002年土耳其的发电量为1600亿千瓦时(kWh)。到2010年,土耳其可能需要将其总发电量增加三倍,达到64千兆瓦(GW)左右。根据能源和自然资源部(MENR)的说法,这还需要每年投资40 - 45亿美元。

The broad objective of this study is to determine the limitations of the three-phase relative permeability estimation technique by using the experimental approach. In order to achieve this goal, three-phase relative permeability experiments were conducted on a Berea sandstone core plug by using brine, hexane and nitrogen gas. An unsteady-state analytical technique and a numerical technique where a black oil simulator was coupled with a global optimization algorithm in a least squares manner was used to compute three-phase relative permeabilities. It has been found that basic assumptions of linear flow and monotonic saturation changes, required for three-phase extensions of two-phase Johnson-Bossler-Nauman (JBN) theory, are violated in the displacement experiments, leading to errors in computed relative permeabilites even at high rates.
本研究的主要目的是通过实验方法确定三相相对渗透率估计技术的局限性。为了实现这一目标,在Berea砂岩岩心塞上进行了盐水、己烷和氮气三相相对渗透率实验。采用非稳态分析技术和数值方法,将黑油模拟器与最小二乘全局优化算法相结合,计算了三相相对渗透率。研究发现,驱油实验违背了两相Johnson-Bossler-Nauman (JBN)理论三相扩展所要求的线性流动和单调饱和度变化的基本假设,导致即使在高速率下计算出的相对渗透率也存在误差。

Abstract The aim of biomass development projects is to identify whether it is possible to utilize biomass in the energy production sector by substituting a portion of conventional fuel by biomass to perform combined combustion. Electricity production from biomass has been found to be a promising method in the near future. The world production of biomass is estimated at 146 billion metric tons a year, mostly wild plant growth. Biomass accounts for 35% of primary energy consumption in developing countries, raising the world total to 14% of primary energy consumption. In the future, biomass has the potential to provide a cost-effective and sustainable supply of energy, while at the same time aiding countries in meeting their greenhouse gas reduction targets. By the year 2050, it is estimated that 90% of the world population will live in developing countries.
生物质开发项目的目的是确定是否有可能在能源生产部门利用生物质,用生物质代替一部分常规燃料进行组合燃烧。在不久的将来,生物质发电被认为是一种很有前途的方法。世界生物质产量估计为每年1460亿公吨,主要是野生植物生长。生物质能占发展中国家一次能源消费的35%,使世界一次能源消费总量达到14%。在未来,生物质能有潜力提供具有成本效益和可持续的能源供应,同时帮助各国实现其温室气体减排目标。据估计,到2050年,世界人口的90%将生活在发展中国家。

By the year 2050, it is estimated that 90% of the world population will live in developing countries.","PeriodicalId":11841,"journal":{"name":"Energy Sources","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2005-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74796978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, effects of coal liquefaction parameters on the removal of oxygen, the higher heating value of char, and soluble products during the catalyst physically mixing or impregnation of the two Turkish lignites were investigated. According to the results, the effects on the higher heating value of char and the soluble products of the reaction parameters were almost similar for both lignites. In the case of catalysts physically mixing, the higher heating value of total soluble products of Beypazari lignite increased as a result of increase in solvent/coal ratio and temperature. In the case of the catalyst physically mixing and impregnation of Tuncbilek lignite, the higher heating value of char and the soluble products was observed to have increased considerably at 350–400°C of the reaction temperature in 10–60 minutes of reaction time. According to the results of FT-I.R., it was observed that functional groups with oxygen (carboxylic, carbonyl and etheric) were decreased or removed completely, depending on the liquefaction conditions.
在本研究中,考察了两种土耳其褐煤在催化剂物理混合或浸渍过程中,煤液化参数对除氧、较高的焦炭热值和可溶产物的影响。结果表明,两种褐煤的反应参数对高热值焦炭和可溶产物的影响几乎相同。在催化剂物理混合的情况下,随着溶剂/煤比和温度的增加,北派扎里褐煤总可溶产物的较高热值增加。在催化剂物理混合和浸渍tunchbilek褐煤的情况下,在反应时间10-60分钟的反应温度为350-400℃时,观察到焦炭和可溶性产物的较高热值显著增加。根据ft - ir的结果。观察到含氧官能团(羧基、羰基和醚基)减少或完全去除,这取决于液化条件。
