Modelling of microbial enhanced oil recovery application using anaerobic gas-producing bacteria

Microbial enhanced oil recovery （MEOR） methods apply injection of bacteria to depleted oil reservoirs to produce oil, which had remained unrecovered after the conventional methods of production. The ability ofthermophilic anaerobic bacteria to produce gas as the main mechanism in potential MEOR in high salinities of 70-100 g/L was investigated in this study. Maximum gas production of up to 350 mL per 700 mL of salty solution was produced at a salinity of 90 g/L stably during 2-4 days of experiment. The experimental results were upscaled to the Snorre Oilfield, Norway, and simulated using ECLIPSE software for 27 months. The best scenarios showed that the increase in oil recovery on average was at 21% and 17.8% respectively. This study demonstrated that anaerobic bacteria used in biogas plants could be an attractive candidate for MEOR implementation due to their ability to withstand high temperature and salinity, and produce gas in large volumes.

基于ECLIPSE图形插件开发的研究

随着Eclipse在JavaIDE开发环境的异军突起,Eclipse这个名词越来越被人关注。Eclipse的成功不仅仅是因为它对JavaIDE的贡献,主要是因为它是一个开源的可扩展的框架,以及基于插件的构架。因为这些特性,使Eclipse集成其他框架成为可能。介绍了利用Eclipse中成功图形框架GEF技术,结合插件扩展技术,来构建一个可拖拉的图形化编辑器。通过图形化编辑器的实现,达到预期的学习和实践目的,为进一步的研究奠定了坚实的基础。     

Constantine: configurable static analysis tool in Eclipse

Static code analysers help in exposing internal code quality problems. For higher effectiveness, they must be pressed into use early during the development of code. They must support the formulation of new coding constraints with relative ease to better cope with variations in coding standards. We present the design of a static analyser that addresses these twin objectives. Our system provides interactive feedback to programmers on the non‐conformances that occur in response to the changes made to the code. Its rule construction framework empowers programmers to define new conformance rules, which can come into effect immediately after creation. The tool has been realized as an Eclipse plug‐in for the analysis of C, C++ and Java sources. Central to its design is the concept of reusing a set of primitive checks by composing them to form new rules. This renders rule construction accessible to programmers, lowers dependence on tool smiths and accelerates the enforcement of custom checks. We also present our experience in defining rules drawn from an industry standard rule set based on this approach. Copyright © 2012 John Wiley & Sons, Ltd.     

On the use of ECLIPSE code for optimizing industrial processes

The sequential code ECLIPSE is used in the present work to perform a technical analysis of two industrial processes—a coke gas cleansing plant and a power plant—aiming their energetic and environmental optimization. The code is validated herein comparing its results against existing experimental data acquired at the above-referred plants, for the present operating conditions. Agreement is observed to be rather good. In order to optimize both processes as far as energy and environment aspects are concerned, alternative unit operations are suggested and are included in the production flow sheet and entirely new processes are simulated. The improvements attained in both processes are noticeable. Therefore, ECLIPSE proved to be an adequate tool for global industrial processes simulation, analysis and optimization. However, the code exhibits some limitations in simulating detailed complex physical phenomena, such as combustion. © 1998 John Wiley & Sons, Ltd.     

Visual Basic在油藏数值模拟中的应用

随着油藏数值模拟技术的发展以及油藏数值模拟软件的不断改进和完善,油藏数值模拟软件在油田开发中的应用越来越广泛。对油藏数值模拟软件计算出的数据进行整理不仅枯燥而且花费了大量时间。本文利用Visual Basic语言编制了处理ECLIPSE软件生成的油气田开发指标数据软件（RS—MAN）。该软件方便了油气田开发指标的整理和汇总,软件界面友好,操作简单。     

The ECLIPSE user interface

This paper describes the user interface facilities of the ECLIPSE integrated project support environment. This interface is based on a consistent metaphor called the ‘control panel’ metaphor and includes standard help and message-handling systems. The paper describes these as well as some of the interface standards which have been developed. The interface has been implemented on top of the ‘applications interface’, which provides a portable, hardware-independent interface for software tools.     

缝洞双重介质数值模型及渗流特征研究

按储层特征和渗流特征,将缝洞双重介质模型分为三类,从数学角度简化成两类模型,即裂缝-基岩型和裂缝-孔洞型.前者采用Woren-Root等常规双重介质模型,后者需要建立缝洞系统的窜流公式才能进行数值模拟计算.根据缝洞的组合特征以及裂缝中的压力分布特征,推导了缝洞介质的窜流计算公式,并以商业软件ECLIPSE为基础,通过修改特定的关键字,实现缝洞双重介质模型的等效模拟.在此基础上,研究分析了缝洞双重介质的渗流特征:当窜流系数较低,单相流的双对数试井曲线出现凹形特征;当窜流系数足够大,单相流的曲线形态与单一介质相似,不出现凹形特征,但油水两相流动可导致油井的含水率出现阶梯状.     

Energy and environmental analysis of an entire coke production plant using ECLIPSE

In the present work the sequential code ECLIPSE is used to perform an energy analysis of an entire industrial process—a coke production plant—aiming its characterization and optimization in terms of energy requirements and environmental impact. The code is validated by comparing its results against existing experimental data acquired at the above‐referred plant, for the present operating conditions. Agreement is observed to be rather good, as the maximum relative errors between the ECLIPSE predictions and the actual values are 9.2, 9.7 and 8.7 per cent, respectively, for mass flows, temperatures and pressures. Moreover, those errors occur only once and at different streams, the vast majority of the relative errors for the remaining streams being below 1.0 per cent. In order to optimize the process both as far as energy and environmental aspects are concerned, alternative or new unit operations are suggested and are included in the production flow sheet or added to it and the entire new processes are simulated. More specifically, the better sealing of the coke ovens doors eliminating 80 per cent of the volatiles escape, the recovery of the lost sensible heat in the coke extinction operation and the restart of the 10 non‐productive coke ovens would yield remarkable energy savings—losses would reduce from 46 440 to 9260 kW, apart from the environmental benefits emerging from the elimination of the volatiles escape to the atmosphere. In addition, for the coke gas cleansing sub‐process, the substitution of the stripping process in the column distillation by a separation process, making recourse to a reverse osmosis installation, together with the operation setting of the ammonium destruction oven at a more convenient temperature, would allow both for energy savings of 66 per cent and a substantial reduction in both gaseous and liquid emissions, namely naphthalene, ammonia, nitric oxides and sulphur oxides. The improvements attained are noticeable and encouraging. Therefore, ECLIPSE proved to be an adequate tool for global industrial processes simulation, analysis and optimization, in spite of some limitations exhibited by the code in simulating detailed complex physical phenomena, such as combustion or coal distillation.
