针对大庆油田长期保持稳产(高产)的重要前提之一的低渗透油田的开发,从龙北地区矿场实践出发,在室内试验的基础上,提出了对低渗透油田开发全过程中各个环节进行油层保护技术的观点,通过储层敏感性评价试验、入井流体筛选试验、矿场试验、经济效益分析等几个方面,对低渗透油田的油层保护技术进行了实践和研究。对同类油田的开发具有一定借鉴意义。

For the development of low permeability oilfield,this paper,based on the lab test and field practice in Longbei area,Daqing Oilfield,presents the view of protecting oil reservoir during the whole stage of development.Through the reservoir sensitivity evaluation test,the inflow fluid screening test,the field test,the economic benefit analysis and so on,the oil reservoir protection technique of low permeability oil-field is practiced and studied.The view presented in the paper will be helpful for developing the similar oilfield.
