摘　　要：现有的稠油热采工艺普遍存在生产效率低、工艺流程复杂和液控管线数量较多的问题。针对这些问题设计了一种适用于高温电潜泵注采一体化工艺的新型自动Y工具,可以实现稠油热采过程中注入和生产通道的自动切换,简化了工艺流程,并减少了液控管线的数量。介绍了自动Y工具的设计原理、强度校核和有限元分析,并进行了常规功能性试验、流量试验和隔热试验。结果显示,该自动Y工具能够满足350℃高温电潜泵注采一体化的作业要求,隔热效果良好,最大流量为2.86 m^(3)/min(18 bbl/min)。The existing heavy oil thermal recovery process generally has problems of low production efficiency,complex process flow,and a large number of hydraulic control pipelines.A new automatic Y tool suitable for the high-temperature electric submersible pump injection production integration process was designed to address these issues.It can achieve automatic switching of injection and production channels during the heavy oil thermal recovery process,simplify the process flow,and reduce the number of hydraulic control pipelines.The design principle,strength verification,and finite element analysis of the automatic Y tool,and conducted routine functional tests,flow tests,and insulation tests were introduced.The results show that the automatic Y tool can meet the operational requirements of 350℃high-temperature electric submersible pump injection production integration,with good insulation effect,and a maximum flow rate of 2.86 m^(3)/min(18 bbl/min).
