连续气举井组优化配气研究
Optimized Gas Allocation for Continuous Gas Lift Well Group
摘要:
连续气举井组优化配气可以提高注入气的利用效率。考虑地面集输管线以及油井之间的相互干扰,建立了以产液量最大为目标的气举井组优化配气模型。根据节点分析原理,确定井网中各个节点的流入曲线,从而得到注气量和产液量之间的关系;在此基础上,采用遗传算法求解模型。以一个6口气举井井组为例,确定其合理的总注气量,然后进行单井优化配气。
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.
