Enhanced onshore oil recovery through novel combine heat and power stirling technology

海岛天然气有限公司(IGAS)和垃圾填埋系统维护有限公司(LSL)开发了一种在陆上常规油井场地产生热量和电力的新工艺。该工艺利用英国陆上开采地点常见的低流量气流来驱动一种新型的热电联产斯特林发动机。这将消除抽油所需的电网电力，用来在井口分离油和水的热量(目前在远程处理中心进行运输、整理和去水)。天然气的利用将降低井筒的背压，从而提高流量，提高产量和延长油层寿命。这种低成本的强化采油工艺在减少排放到大气中的甲烷气体方面为操作员和环境提供了及时的好处。技术集成和验证将在IGAS的Scampton井场进行，发动机改装和监测将由专业的天然气开采和管理公司LSL承担。该系统的演示计划在2016年进行，商业部署可能在2017年底开始。

Island Gas Ltd (IGas) and Landfill Systems Maintenance Ltd (LSL) have developed a novel process to generateheat & power at onshore conventional oil wellsites. The process utilises low volume gas flows common to UKonshore extraction sites to power a novel combined heat and power (CHP) stirling engine. This will eliminateneed for grid electricity for pumping oil, with the heat used to separate oil & water at the wellhead (currentlytransported, collated and de-watered at remote processing centres). Gas utilisation will reduce back pressureat the well bore allowing for increased flow rates, enhancing production and extending reservoir life. This lowcost enhanced oil recovery process provides timely benefits for the operator and the environment in reducingmethane gas vented to atmosphere. Technology integration and validation will be carried out at IGas’sScampton wellsite, with engine modifications and monitoring being undertaken by specialist gas extraction andmangement firm, LSL. Demonstration of the system is scheduled 2016 with commercial deployment likely tocommence end-2017.
