优化理论在连续气举系统配气中的应用

An Application of Optimum Theory to Gas Allocation in a Continuous Gaslift Well System

采用优化理论确定优化连续气举系统配气方案,可从系统获得最佳经济效益。提出了连续气举单井经济动态模型及经济动态曲线制作方法,建立了以连续气举系统内所有井的日工作现金收入之和最大为目标函数的优化配气数学模型,介绍了模型的求解方法。根据数学模型和求解方法,编制了优化配气的程序。用它对一个实例系统进行了给定供气量下的优化配气计算。结果表明,根据优化理论确定优化配气方案是合理、可行的。

The economic benefit from a continuous gaslift well system is different by using different project to distribute gas to every well in the system when the gas supply to the system is limited.The optimum economic benefit can be obtained from the system optimum theory used in determining the project of a gas allocation.An economic performance model and drawing method of a performance curve is presented.A model for optimizing gas allocation is developed,the target function which is total daily operation cash income obtained from the system is maximum.A method for solving the model is introduced.A program based on the model and its solving method is established. An example for optimizing gas allocation is calculated by using the program for the given gas supply.The results show that it is reasonable and practical to determine the project of optimum gas allocation based on the optimum theory.
