低渗透凝析气藏开发技术研究

Development Techniques of Condensate Reservoir with Low Permeability

近年来,随着低渗透油气藏的地质储量所占比例的逐步提高,以及国内外石油工作人员对低渗透油气藏越来越广泛的研究,在低渗透油气藏开发方面积累了丰富的经验,形成了一些固定的开发模式。在此,紧密围绕油田攻关项目和现场实际,总结了国内外凝析气藏开发技术现状,阐述了凝析气藏渗流机理,重点介绍了凝析气藏的开发技术和开发方式。

in recent years, with proportion of OOIP of hydrocarbon reservoirs with low permeability increasing and more and more extensive studies about it carried out by petroleum researchers at home and abroad, abundant experiences on development of hydrocarbon reservoirs with low permeability have been obtained, moreover, some stable development models have been formed. Combined the project in which key problems should be tackled and actual situation of the oilfield, state of the art of the condensate reservoir development at home and abroad is summarized, percolation mechanisms are presented, development techniques and models for the condensate reservoir are introduced predominately in the paper.
