压力监测系统优化部署方法研究

Optimization of the pressure inspection system

合理的压力监测系统是进行油田动态监测、动态分析、制定科学的开发调整方案的基础。为此提出了压力监测系统优化部署理论,并对油田压力监测系统优化部署的方法进行了系统研究。把模拟退火算法应用到压力监测系统的优化部署中,以生产井的产量、地层系数以及空间相对位置作为约束条件,以其方差作为优化的目标函数,建立了压力监测系统优化部署理论模型,并得出压力监测系统优化部署的具体方法。利用该方法对油田开发区块的压力监测系统进行了优化模拟,结果表明,任何两个相邻的井点不再同时作为监测井点,任一井点附近必有一个监测井点与之相邻。

An optimized pressure inspection system is always desired for reservoir dynamics analysis and development. With flow rate, stratum coefficient, and relative position as constraints, and with the value of variance as optimized objective function, simulated annealing method is applied to test an optimum theoretic model for pressure inspection system. A practical method was then tested for determination of the optimum pressure inspection system. The results indicate that the spatial distribution unbalance problem of the original inspection system is minimized. Applying this method, two adjacent wells will no longer serve as each other's reference well. Meanwhile, any well has a reference well nearby.
