Abstract: 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.

Key words: gas lifting allocation optimization, piece-wise linear function, genetic algorithm, multi-objective optimization
