项目摘要

In order to ensure future energy security, sources of fuel that are considered unconventional today must be developed, including the existing vast heavy oil and bitumen reserves. Although there are large reserves of such oils in Canada and Venezuela, the techniques could potentially be applied in other parts of the World, e.g. sub surface recovery in partially depleted wells in the North Sea. In order to minimise the environmental impact of extraction of these reserves as much of the processing should be done sub-surface as possible, thereby reducing the requirement for expensive hydrogen and additional energy needed in 'surface upgrader' refineries. This project aims to develop an oil upgrading 'plant' to run underground, in conjunction with the oil recovery process itself, such that it has minimal surface footprint and confines emissions underground. In order to do this we will deploy several technologies in combination: Toe-to-Heel Air Injection (THAI) is an in-situ combustion technique which combusts a small fraction of the oil to generate heat for thermal upgrading and cracking of oil molecules to lighter components required for transportation fuels. Previous work has shown that upgrading is potentially possible underground but that a new solution is necessary to achieve the optimum conditions for downhole processing. In particular, the temperature achieved may not be high enough to achieve the required improvement, therefore we will develop and trial the application of microwave and ohmic heating to increase the well temperature and deliver further upgrading. The addition of a catalyst to the well can bring added value to the product oil by facilitating catalytic cracking reactions which improve its properties. However the application of the above techniques in combination has not been previously investigated, hence this project will combine thermal and electromagnetic approaches to create a new hybrid technology capable of efficient downhole upgrading, and aims to optimise the catalyst formulation to use with this technology. The special and difficult conditions that exist underground require the development of a novel, idiosyncratic catalyst to meet the particular needs of the new process.The work is expected to deliver new reactor designs capable of combining heavy oil upgrading with microwave and/or ohmic heating and novel catalyst formulations that could be deployed in-situ within the oil well. Laboratory scale upgrading data will be collected to determine how well these techniques work together and process scale up designs proposed that could potentially be applied to take the technology in to the oil reservoir. The proposed technologies are expected to deliver a number of potential benefits including improved energy security, wealth creation and employment in the energy extraction industry, reduced carbon dioxide emissions, reduced external energy requirement in extracting the oil, UK held intellectual property and patents.

为了确保未来的能源安全，必须开发今天被认为是非常规的燃料来源，包括现有的大量重油和沥青储备。虽然在加拿大和委内瑞拉有大量的这种石油储量，但这些技术有可能应用于世界其他地区，例如北海部分枯竭的威尔斯井的地下开采。为了最大限度地减少开采这些储量对环境的影响，应尽可能多地在地下进行加工，从而减少对昂贵的氢气的需求和“地表精炼”炼油厂所需的额外能源。该项目旨在开发一个石油升级“工厂”，与石油回收过程本身一起在地下运行，使其具有最小的地表足迹并将排放限制在地下。为了做到这一点，我们将结合使用几种技术：脚趾到脚跟空气喷射（THAI）是一种原位燃烧技术，燃烧一小部分石油产生热量，用于热升级和石油分子裂解为运输燃料所需的轻质组分。以前的工作表明，升级是可能的地下，但一个新的解决方案是必要的，以实现井下处理的最佳条件。特别是，达到的温度可能不足以实现所需的改进，因此我们将开发和试验微波和欧姆加热的应用，以提高井温并实现进一步升级。向井中添加催化剂可以通过促进催化裂化反应而为产品油带来附加值，从而改善其性质。然而，上述技术的组合应用以前尚未研究过，因此该项目将联合收割机结合热和电磁方法，以创建能够有效井下升级的新混合技术，并旨在优化与该技术一起使用的催化剂配方。地下存在的特殊和困难的条件要求开发一种新型的、特殊的催化剂，以满足新工艺的特殊需要。这项工作预计将提供新的反应器设计，能够将重油改质与微波和/或欧姆加热相结合，以及可以在油井内就地部署的新型催化剂配方。将收集实验室规模的升级数据，以确定这些技术如何协同工作，并提出可能用于将该技术应用于油藏的工艺放大设计。预计拟议的技术将带来许多潜在的好处，包括改善能源安全，创造财富和能源开采行业的就业机会，减少二氧化碳排放，减少开采石油的外部能源需求，英国拥有的知识产权和专利。
