摘要
本文立足大庆某低渗透油田超前注水区块生产数据,选取与超前注水区块物性相近的同步注水、滞后注水井区,从不同注水方式井区的地层压力水平、采油强度、含水率与采出程度关系等五个方面,分析采用不同注水方式的油田开发效果。通过上述开发初期的开发效果分析可知,与同步注水、滞后注水方式相比,超前注水可保持较高的地层压力水平和压力系数、较高的采油强度,同时具有单井产量递减幅度低、含水上升率低等特点。
This paper describes the research on the effect evaluation for advanced injection development in Daqing low permeability oilfield.The synchronous injection and delayed injection blocks that have similar physical properties with the block were selected for comparison from formation pressure,oil production,water content and degree of recovery in different injection ways.The results show that advanced water injection can maintain a higher formation pressure,pressure coefficient and oil production per well compared with synchronous and delayed injection.It also features small single well production decline rate and water cut rate.
