摘　　要：油田油井加密可以解决油田进入开发中后期后出现的一系列问题,在提高产量的同时,会导致地面注水系统的改变。油田注水管网属于枝状管网,其计算复杂,在实际的设计中通常采用人工经验连接,因此,得到的方案无法达到最优。针对油田老区注水井加密后的状况,建立适合计算机求解的老区加密井注水管网优化数学模型,利用计算机编制算法制成软件求解最优化解,得到加密后注水管网最优化的运行方案。对老区已有的注水管网进行计算机模拟,对注水井加密后注水管网的优化采用分级优化,主要包括管网的布局优化和参数优化。实例计算结果表明,采用计算机优化算法得到的结果优于人工优化得到的结果。Infilling wells in old oilfield can solve a series of problems, happening in the later stage of oilfield development, like changing ground water injection system while increasing production. In most situations only experiences were used before for the design of the layout of connection of oilfield water injection pipe network, which was a kind of dendritic pipeline network with complex calculation, the solution, therefore, could not be optimum for the project. According to the situation of infilling wells in old oilfield, computer optimization math model was put forward to get the optimum operation scheme. Having applied the math model in the existing water injection pipe network in old oilfield, the water injection pipe network with infilling wells was then hierarchically optimized, mainly including pipe network layout optimization and parameter optimization. It was shown in practice cases that the result from computer optimization was better than manual work.
