气田短期生产调度方案的优化决策方法研究

摘要

In order to adapt to the productivity substitution of the new and old blocks, and seasonal and time period variation of natural gas demand, gas field needs to deploy and adjust scheduling scheme continuously. With total gas field output,giving priority to development principle, or quality control of raw gas in natural gas treatment plant for control targets of optimal decision of short-erm scheduling scheme, based on the regional distribution of production capacity in each block, process flow and equipment configuration of gathering pipeline network system, the treatment capability of treatment plant and external environment conditions, achieve the optimal arrangement and coordination of the operation parameters of pipeline networks and block production, making carrying capacity of gathering pipeline network in conformity with the gas field allocation production, raising the utilization rate of production equipments in gas field efficiency and reducing production costs to reach the best economic effects.%为了适应新老区块的产能接替和天然气需求量季节性和时段性的变化,气田需要不断对生产运行调度方案进行部署和调整.以气田总产量、指定区块优先开发原则或天然气处理厂原料气质量指标控制为气田短期生产调度方案优化决策的控制目标,根据各区块的生产能力区域分布,集输管网系统的工艺、设备配置、天然气处理厂处理能力和要求及外部环境条件,实现区块产量与管网运行参数的最佳配置与协调,使集输管网输送能力与气田配产相适应,有效提高气田生产设备的利用率,降低生产成本,使气田达到最佳经济效益.
