摘　　要：随着油田堵水调剖技术的发展,注入聚合物的种类逐渐多样化,对聚合物的配置精度和效率提出了更高要求。为满足局部区块堵水调剖作业需求,研制了一套用于自动混配和注入的地面配注系统,该系统包括进料、熟化、泵注、井口和监控5个主要模块,可用于2种粉状和2种液态物料的分别或同时配注。根据堵水调剖工艺要求,设计了总体结构方案,针对关键模块和装置开展了结构优化。考虑粉状物料的离散颗粒特性,设计了以螺旋输送和射流吸入方式相结合的进料装置,实现了定量和连续进料;通过配置2套搅拌罐,并由监控系统对各模块工况监测和控制,交替完成熟化和泵注,确保连续不停机工作。现场应用表明,该系统可实现“两固两液”物料同时或分别配注,不需要人工上料和操作,配置精度和可靠性适应堵水调剖工艺要求。研制与研究为装置的推广应用奠定了基础。As the water plugging and profile control technology develops in the oilfields,the types of injected polymers are gradually diversified,which puts forward higher requirements for the preparation accuracy and efficiency.To meet the requirements of water plugging and profile control operation in local block,a surface mixing injection system used for automatic mixing and injection was developed,including four main modules:feeding,curing,pumping and monitoring,which could be used for separate or simultaneous mixing injection of two types of powder and two types of liquid materials.Based on the requirements of water plugging and profile control technology,an overall structural plan was designed,and structure optimization was carried out for key modules and devices.Considering the discrete particle characteristics of powdered materials,a feeding device combining screw conveying and jet suction was designed to achieve quantitative and continuous feeding.Two sets of auger tanks were equipped,a monitoring control system was used to monitor and control the working conditions of each module,and curing and pumping were alternately completed to ensure continuous and uninterrupted operation.Field application shows that the system can achieve simultaneous or separate mixing injection of“two solid and two liquid”materials,without the need for manual feeding and operation,and the preparation accuracy and reliability meet the requirements of water plugging and profile control technology.The field application results lay a foundation for the popularization and application of the system.
