# 连续气举井组优化配气研究Optimized Gas Allocation for Continuous Gas Lift Well Group

Abstract: The optimized gas allocation for a continuous gas lift well group could enhance the utilization effi-ciency of injected gas. In consideration of the surface gathering pipelines and the interference between each oil well, an optimized gas allocation model of the gas lift well group was established to maximize the liquid production rate. According to the node analytical principle, the inflow curve of each node in the well pattern was determined, therefore the relationship between the injection gas rate and the liquid production rate was established. Based on the previous study, the genetic algorithm is adopted to solve the model. By taking a well group with six oil wells for example, the reasonable total gas injection rate is determined, and then optimized gas allocation in single well is implemented.
