摘　　要：在水驱油藏开发的中后期,提液是保持稳产和提高采收率的有效手段,确定提液时机和提液幅度直接影响后期开发效果。以均衡驱替程度最大化为目标,以提液井的提液时机和提液量为优化变量,建立了异步提液参数优化数学模型,基于Piecewise混沌映射和随机游走策略改进的蜣螂优化算法进行求解,形成了高含水率期油藏异步提液参数一体化智能优化方法。应用该方法对南海东部L油藏进行了异步提液参数优化,与同步提液相比,异步提液优化调整的均衡驱替程度更高;相比优化前,油藏整体提液幅度增加约1.58倍,采收率提高7.18%,实施异步提液参数优化可进一步改善油田的水驱开发效果。In the mid-to-late stages of waterflooding reservoir development,liquid lifting is an effective means to maintain stable production and enhance recovery rates.The timing and magnitude of liquid lifting significantly impact the effectiveness of later-stage development.By targeting maximum displacement equilibrium and treating the timing and volume of liquid lifting wells as optimization variables,an asynchronous liquid lifting parameter optimization model was developed.This model is solved using an enhanced dung beetle optimization algorithm based on Piecewise chaotic mapping and random walk strategy,forming an integrated intelligent optimization method of asynchronous liquid lifting parameters for high water-cut period reservoirs.This method was applied to optimize asynchronous liquid lifting parameters for the L reservoir in the eastern South China Sea.Compared to synchronous liquid lifting,asynchronous liquid lifting optimization achieved a higher degree of displacement balance.The overall liquid lifting magnitude increased by approximately 1.58 times,and the recovery rate improved by 7.18%.Implementing asynchronous liquid lifting parameters optimization further enhances the waterflooding development effect in oilfields.
