摘　　要：目前世界稠油资源极为丰富,全球储量超过6万亿桶,在我国储量也极为丰富,与常规原油不同,稠油具有特殊的高粘度和高凝固点特性,开发难度大、成本高,常规开发方式在成本、环保等方面不具有竞争力。目前,行业内最常用的开采方法是原位加热(蒸汽、火烧油层等),即通过热处理降低油品粘度,增强流动性,以提高油气采收率。本文介绍了一种用热处理地下油藏以引起气化、水蒸气推移和/或水热裂解反应生成氢气,并通过在生产井中安置仅氢气可渗透的薄膜过滤系统,将氢气单独地生产至地表的工艺方法[1]。目前,该方法还属于前沿科技,并未完全实现产业化,但是通过验证,此方法具有广阔的推广应用前景。At present,heavy oil resources are extremely rich in the world,with global reserves exceeding 6 trillion barrels,and abundant reserves in China.Different from conventional crude oil,heavy oil has special characteristics of high viscosity and freezing point,so it is difficult and costly to develop.Conventional development methods are not competitive in terms of cost and environmental protection.At present,the most common method used in the industry is in situ heating(steam,fire formation,etc.),which is heat treatment to reduce oil viscosity and enhance fluidity to improve oil recovery.This paper describes a process of heat treating an underground reservoir to generate hydrogen gas in response to gasification,steam passage and/or hydrothermal pyrolysis,and producing hydrogen individually to the surface by installing a hydrogen-only permeable membrane filtration system in the production Wells[1].At present,this method is still a frontier technology and has not been fully industrialized.However,through verification,this method has broad prospects for popularization and application.
