摘要 井网加密是油田开发调整最重要的措施之一,井网是否合理直接影响到油田开发效果。从大庆油田L试验区块加密前实际生产状况出发,结合现场实际井网,设计出不同的加密方案。计算了各方案条件下水驱控制程度、采收率等开发指标。结果表明,75 m×75 m五点法井网的加密方案可以有效改善水驱开发效果,提高采收率。 Well pattern thickening is one of the most important oilfield development pattern whether reasonable directly affect the oil field development effect. From daqing adjustable measures, Well oil field L test block before actual production situation of encryption, on the analysis of the reasons of the poor development effect basis, combining with the actual well pattern, to design the different encryption scheme are presented. Each scheme water flooding control degree, recovery and other development indicators are calculated. The results show that 75 m × 75 m five spot well pattern of the encryption scheme can effectively improve the development effectiveness of water flooding, enhanced oil recovery.
