摘　　要：论述了气举优化配气的发展现状,提出了一种新的用分段线性函数表示的气举优化配气单目标和多目标模型。单目标模型以产油量最大为目标函数,而多目标模型以产油量最大且注气量最小为目标函数。以我国西部某油田某区气举井为例,进行了气举优化配气实例分析,给出了气举配气单目标模型的最优解和多目标模型的非支配解集,得到了最优配气方案下的产油量和注气量。Authors of this paper clarify the developing situation of gas lifting allocation optimization.A new gas lifting allocation technology of single and multi-objective optimization are developed by using piece-wise linear function.The single objective model takes maximun deliverability as objective function and multiple objective function takes maximun oil deliverability and minimun gas deliverability as objective function.Taking gas lifting oil wells of block four in Zhongyuan Oilfield as an example,the gas lifting allocation optimization is verified with the optimal solution of single objective model and non-dominated solution sets of multi-objective model.Results show that the proposed method is effective for gas lifting allocation optimization.The oil deliverability and gas injection amount are acqured under the condition of optimal gas lifting allocation.
