摘要
低渗透油藏物性条件差 ,常规注水难以达到配注要求 ,注水效果不理想。采取高压注水措施 ,可以有效提高注水量 ,促进油井见效增产 ,达到提高低渗透油田注水波及效率和采收率的目的。本文总结了近几年来江汉油田高压注水的实践效果 。
The physical properties of low permeability reservoirs are very poor, and the effectiveness of water injection with conventional injection pressure in low permeability reservoirs is not so good, because it is very difficult to meet the requirement for water injection allocation with conventional injecting pressure in low permeability reservoirs. Water injection rate can be improved and oil production can be increased by high-pressure water injection in low permeability reservoirs. In addition, water-flooding sweep efficiency and oil recovery can also be improved greatly. This paper summarizes the experiences and practices of high-pressure water injection in low permeability reservoirs, which are very significant to the development of other low permeability reservoirs with high efficiency.
