与同步注水相比,超前注水开发方式在合理补充地层能量、提高地层压力及保持油井较高生产能力等方面的优势更加明显。A油田是一个典型的低渗透裂缝性油田,为持续有效开发,选择B区块开展超前注水试验,通过开发效果分析,认为超前注水是提高低渗透油藏水驱开发效果的有效途径。 Compared with synchronous water injection, the advantages of advanced water injection development are more obvious in terms of rational replenishment of formation energy, improvement of formation pressure and maintenance of higher production capacity of oil wells. A oilfield is a typical low permeability fractured oilfield. For the continuous and effective development, the B block is selected to carry out the advanced water injection test. According to the development effect analysis, the advanced water injection is an effective way to improve the waterflooding development effect of low permeability reservoirs.
