摘要
原有气井分类方法,主要是利用井口压力和产量进行分类,分类指标只考虑了气井动态产能的一个方面,气井在分类开发与管理过程中发现部分井与其同类井的生产特征不一致,需要重新划分井型。为此,结合气井生产实际,优选井控储量、地层压力、地层系数等,通过灰色关联分析法确定各项参数权重,建立综合评价系数计算公式,优化气井配产方法,对气田各井进行重新分类、配产,制定不同类型气井合理工作制度。生产实践表明,气井综合分类法,分类可操作性强,分类结果与实际相符,相应的配产方法有利于指导气井合理配产和管理。
In combination with actual production,preferably controlled reserves,formation pressure and its coefficient etc,agrey correlation analysis is used to determine the weight of each parameter,classification coefficient formula,optimization of production proration method,re-classification and production proration,reasonable working system is established for different types of gas wells.The production practice shows that the comprehensive classification method has strong operability,the results are consistent with the actual production,the corresponding production proration method can guide reasonable proration and management.
