【摘要】 提高石油采收率是油田开发永恒的主题,以北美国家为代表,世界提高石油采收率技术现以蒸汽驱为主导,注气驱具有很大的潜力和发展前景,化学驱不多。中国油田类型多,地质情况复杂,不应局限于水驱和化学驱,应因地制宜多元化地发展提高采收率的技术。注气驱(CO2、烃气、N2、烟道气、空气等)已在各大油气区探索发展,日益兴旺,但限于气源、注气设备、陆相地层复杂和观念转变等原因,还未取得突破性的规模化效应。注气技术发展的关键在于精心设计和施工,一切通过实践,在实践中积累经验,逐步形成了十项配套技术,培养了一批专门技术人才。在吸收国外先进技术和外资的基础上,发展中国高压注气设备势在必行。更多还原

【Abstract】 Improving oil recovery is one consistent theme in oilfield development. At present,steam flooding is mainly used for improving oil recovery all over the world. Gas injection flooding has great potential and development prospect and chemical floodingis little used. There are manytypes ofoilfields in China and their geological conditions are very complex,all kinds of technologies for improving oil recovery shall be developed according to local conditions except for water flooding and chemical flooding. Gas (CO 2 ,hydrocarbon gas,N 2 ,flue gas,air,etc.)injection flooding has been explored and developed in all large oil and gas areas. However,scale effect has not been formed due to not advanced injection equipment,complex continental strata and not changed ideas. While foreign advanced technologies are absorbed and foreign investments are introduced,it is imperative that domestic high pressure injection equipment is developed rapidly. It is believed that injection technology will certainly become more and more advanced and mature as soon as constant practice and summaryare done and continuous improvement is conducted.更多还原
