石油的主要成分是甲烷,同时也含有少量的乙烷和丙烷还有一氧化碳、氮气等等,通过对石油的炼制可得到汽油、柴油、煤油灯燃料还有气态烃和各种机器的润滑剂,因此,石油是工业的血液,是国民经济发展的支柱能源,同时也是社会经济发展与人民日常生活都不可缺少的重要能源,因此,研究发展石油安全有效开采的技术,实现国家能源安全与环境保护和经济持续增长,是目前石油开采工作的核心。本文从分层采油管柱、分层注水管柱的结构、特性以及适应条件和稠油开采工艺等方面,讲述了油田机械分层开采技术的发展与应用,分析了油田分层开采工艺在油田开发中的作用。
The main components of oil are methane, but also a small amount of ethane and propane, as well as carbon monoxide, nitrogen and the like. Petrol, diesel, kerosene lamp fuel and gaseous hydrocarbons and lubricants for various machines can be obtained by refining petroleum Therefore, oil is the blood of industry and the pillar energy for the development of the national economy. It is also an indispensable and important source of energy for social and economic development and people’s daily life. Therefore, it is necessary to study and develop technologies for the safe and effective exploitation of oil so as to achieve the national energy security and environment Protection and sustained economic growth are the core of the current oil exploration. In this paper, the development and application of mechanical stratified mining technology in oilfield are described from the aspects of structure, characteristics, adaptability and heavy oil extraction technology of stratified production tubing string and stratified water injection string. The effects of stratified mining technology in oilfield The role of development.
