摘要: 考虑分层注水的井筒约束方程作为内边界条件,基于黑油模型建立精细分层注水约束的油藏数值模型,形成带有加边七对角稀疏系数矩阵的封闭线性系统,采用分块矩阵乘法与预处理共轭梯度法相结合的方法进行求解.通过实例计算五点井网分层注水与笼统注水的开发效果,评价不同分段和配注模式对开发效果的影响.

关键词: 分层注水, 共轭梯度法, 油藏数值模拟, 非均质性, 油藏采收率

Abstract: Wellbore constrained equations were deduced considering separated layer water injection in a heavy oil model. A numerical model constrained by fine separated layer water injection was constructed. A linear system consisted of a seven-diagonal sparse coefficient matrix with attached columns and rows was derived, which was solved by partitioned matrix multiplication combined with preliminary treatment of conjugate gradient. Development effects of separated layer water injection and generalized water injection were compared and influences of segmentation and injection allocation models were assessed.

Key words: separated layer water injection, conjugate gradient, numerical reservoir simulation, heterogeneous, recovery
