摘　　要：基于天然气管线温度预测和天然气水合物生成条件,建立了苏南井丛合理注醇量的计算方法,通过现场试验对优化注醇进行了验证,通过注醇优化可以显著降低注醇量,减少注醇泵故障率,降低生产成本,节约用工成本,精细化管理为降本增效提供有利支持。The calculation method of reasonable alcohol injection rate of well cluster in south Sulige block is established based on the temperature prediction of natural gas pipeline and the formation conditions of natural gas hydrate,and the optimized alcohol injection rate is verified by field tests.The optimization of alcohol injection rate can significantly reduce the amount of alcohol injection,the fail⁃ure rate of alcohol injection pump and the production cost,save the labor cost,and provide the favorable support for cost reduction and efficiency increase.
