油田注水开发后期提升采油率的技术措施

Technical Measures for Increasing Oil Recovery in the Late Stage of Oilfield Water Injection Development

为保持或提高油层压力,油田企业常采用油田注水方式开发油田。在油田注水开发环节,合理选择注水时机,科学应用注水开发技术是提高采油率的关键。以提升油田注水开发采油率为目标,结合油田注水开发现状和实践经验,对油田注水开发后期提升采油率的措施进行探讨。

In order to maintain or increase the pressure of the oil layer,oilfield companies often use oilfield water injection to develop oilfields.In the oilfield water injection development link,rational selection of water injection timing and scientific application of water injection development technology are the key to improving oil recovery.This paper aims to increase the oil recovery rate of oilfield waterflooding development,combined with the current situation and practical experience of oilfield waterflooding development,and discusses the measures to increase the oil recovery rate in the late stage of waterflooding development of oilfields.
